TIME SHIP STRUCTURE

THE OUTER-HULL

The outer-hull is composed of three distinct and separate layers of material, all sandwiched together in a space of around 15cm. The outer-hull layers are:

•The outer plasmic-shell. This plasma-related substance surrounds the outside of the craft. It has the ability to rap around any object, change colour and can appear to be made from any material with any surface texture. The outer-plasmic shell can transform into any object, this it does with the aid of the chameleon circuit. Once the circuit has changed the exterior form, the outer plasmic-shell will appear to mimic the object that was first scanned. However, the outer plasmic-shell has a re-enforced sub-atomic forced matrix structure imposed, which ensures the strength and durability of the outer shell. In addition to the material strength achieved by this method, the actual matter itself is in a special cold plasma state, hence plasmic-shell. The matter in this form exhibits tremendous resistance to vibration, disruption, environment change and energy input.

•The molecular core. Whereas the outer plasmic-shell has a variable atomic structure, the molecular core is composed of a special interlocking lattice of combined cold plasma metals and crystal, to create a very special plasmic material. The molecular core re-enforces the outer plasmic shell, as it can sometimes exhibit weaker properties when modelling a weak substance. The molecular core more than compensates for this flaw.

•The material barrier. A brickwork shaped barrier exists both inside and outside the ship. The multi-dimensional barrier is not a cold plasma substance, but is made of a restricted crystal matrix of argonite with durilium impurities. In addition, bands of machonite run criss-cross over the surface, this is what gives the barrier a brickwork look. A minor amount of other impurities (type classified) also exist in a sub-atomic state within the material. The wall exists to serve as a last barrier, in the case of total plasmic systems shut-down. It is not indestructible, but is very durable and can absorb minor amounts of energy. It also serves as the last interior wall, the limit of the interior dimension.

The outer-hull of the TARDIS is not indestructible, though for most environments and situations it appears to be so. Refer to the list below.

•The TARDIS can withstand the blast from an energy weapon or a projectile launcher fired at point blank range at the any part of the outer plasmic shell. This includes weak looking sections, windows and semi-translucent shell patches. The outer plasmic shell or hull has the same molecular strength all over -- even the door, when closed, is bonded with the hull with the same strength as the rest of the exterior shell.

•The TARDIS can safely withstand the blast from 400 megatonnes of TNT or 44 megatonnes of nitronine detonated point black. Increasing the amount of explosives above 500 megatonnes of normal TNT and malfunctions and structural damage start to occur. After 550 megatonnes of TNT or more than 61.11 megatonnes of nitronine, the outer structure atomic-lattice breaks up, letting energy through, and the complete outer plasmic shell structure starts to breaks up. The result is that the whole TARDIS is reduced in size and is completely destroyed. To avoid such disaster, the HADS circuit should be used.

•The TARDIS is fully water, fire and shock proof. No amount of normal fire, water or shock waves will damage the exterior, although shock waves can penetrate into the interior. The TARDIS will float if immersed in any liquid; if the TARDIS is materialised underwater then it will neither sink nor float, rather it will remain stationary.

•The TARDIS cannot create propulsion fields stronger than that of a black hole. Although the source of the TARDIS's power comes from a black hole, there is a considerable power loss in the transportation of the energy from a black hole. A black hole's electromagnetic and gravitational fields are stronger than the TARDIS's own projected fields. This rule apples to normal space and to inside the space-time vortex. The TARDIS can create propulsion fields stronger than that of a naked singularity, though the gravitational fields produced by the phenomena can partially disrupt the flight path of the TARDIS.

•The TARDIS cannot be taken through a hydrogen in-rush. A hydrogen in-rush, or a reversal of time to Event One, is an event that no matter can survive, not even a TARDIS. The particles and energy thrown out by Event One is so enormous that no material object can pass through.

•The TARDIS can withstand a very high impulse shock. Although the shock of the impact would not damage the TARDIS, it could be devastating to the occupants inside. For example, the TARDIS could survive a meteorite storm (in the real universe, of course), although the bombardment could damage many interior systems.

•The TARDIS cannot pass through a supernova in the real universe. The reasons for this are really the same for the Event One question. The energy, particles and plasma ejected from a supernova are greater than the energy holding together the structural bonds of the outer plasmic shell.

•The TARDIS's outer plasmic shell cannot withstand intense anti-matter bombardment. Although annihilation of outer layers of electrons will not do much damage on a small scale, and positron bombardment can be withstood without outer structural malfunction for a short period of time, bombardment with from anti-atoms, anti-molecules, anti-ions, etc., will seriously disrupt the outer plasmic shell structure.

EXTERIOR TO INTERIOR WAVE CONDUCTION

Although it is mentioned in section 3.1 that the TARDIS can withstand some of the above forces, the impact of the force will be felt inside the TARDIS. Also, all exterior gravity applies to the interior of the TARDIS unless artificial gravity is being generated. All conducting wave energy's are passed on into the interior of the TARDIS, although the absorption factor of the exterior shell can absorb most of all of common waves. Refer to the list below.

•Microwaves, gamma waves, light waves, ultraviolet and infrared waves are all reflected off the exterior shell, as are alpha, beta and delta particles.

•Radio, sound and shock waves do reach the interior dimension, although the resulting wave's amplitude entering the exterior is many times smaller than the original intensity. The effect is greatly observable with sound waves. Extremely strong waves of the aforementioned kind can also penetrate from the real world to the space-time vortex and then into the TARDIS.

•Cosmic rays and cosmic particles do not pass through the exterior shell.

•Certain influxes of electromagnetic fields do reach the interior, as do certain undefined energy waves.

•Very strong mental and artron energy intrusions can invade the TARDIS and touch the minds of those inside.

Taking these rules into consideration, follow the example below:

A fission grenade is placed next to the TARDIS and detonated. Although the exterior is not harmed, the shock waves caused by the bomb have damaged the central control console, knocked the operator or pilot senseless and taken down some interior wall. The outer plasmic shell was not harmed by this explosion, but the resulting shock waves were passed through to the interior causing a considerable amount of damage.

SHOCK ABSORPTION

The shock absorption envelope is the name given to the effect of the event of exterior energy/ shock/ inertia/ momentum being lessened almost to the point of insignificance. This is because the interior exists within a separate (though relative) dimension to the exterior. Whilst the TARDIS travels in the space-time vortex, it is subjected to a variety of extremes, including gravitational forces, and wide range of telocities and relocities. Without a transcendental interior, the occupants of the TARDIS would be subjected to such forces that there bodies, and all interior equipment would be stretched and stressed. Normal humanoid body systems would shut down and death would occur within minutes. Normal functions such as breathing would become impossible in such gravitational and forceful extremes.

To understand the situation, the structure of the interior dimension must be understood (see 3.7). Now, the interior dimension exists within an envelope, a naturally occurring phenomena which always exist around the Natural Coordinate. This envelope contains the entire interior dimension, inclusive of the material barrier. Stray delta particles may also be present within the envelope. This super-dimensional envelope ensures that the TARDIS is not usually subjected to the extremes of time travel.

However, the TARDIS interior is not completely immune to outside forces. Extremely high gelocities could result in a conduction of these outer extremes. This effect happens as the interior envelope touches the outer boundary of the artificial dimension. This allows strong forces to seep through, although in a weakened form, thanks to the dimensional integrator. Extremely strong gravitational and electromagnetic forces may conduct through, as does the inertia resulting from high geceleration. Superluminal relocities are naturally compensated up to a point, but at the maximum relocity the effects will begin to show. Extremes of any energy from (kinetic, artron, etc.) may also penetrate.

Forces may also seep from the space-time vortex. Due to the dimensional integrator, course changing while following a time path may result in a slight movement, the cause of this movement stems from the fact that normal geceleration and gelocity present no problem, it is a sudden change in geceleration and gelocity which can be felt. This is because dimensional integrator is limited in function to what it can do to minimise transduction of vortex forces.

THE DIMENSIONAL BRIDGE

The Dimensional Bridge allows the various instruments to monitor the primary space outside the TARDIS. It also allows some matter transfer, for example, air, to reach special systems of the TARDIS. The dimensional bridge works, like the main door, by selectively excluding limbo barriers from key positions. This could be dangerous, but the outer plasmic hull is set to a multi-direction barrier at the key position, so that instruments can measure and the scanner visual circuit can see out, and from the outside, only selected amounts of air can enter.

The aforementioned barrier is created by the defensive mechanism, which creates a shielded area over the Dimensional Bridge Opening (DBO). On the exterior side, the shell is of the same material over the DBO than of everywhere else. The dimensional bridge is completely air tight from the inside and occupies the following dimensions: 3 cm height, 5 cm wide and 7 cm in length. The DBO is based on the beacon on top of the TARDIS, which may be disguised as another shaped object. To unseal the DBO patch, just unlock the TARDIS. The patch will re-seal once the main door is closed and locked.

Several circuits have sub-systems located within the DBO, or are entirely located within the dimensional bridge. The scanner circuit and the microphone workings are located behind the access point of the DBO, and the sensor-detector sub-systems are located here in part. The dimensional integrator has a sub-circuit placed here, and the oxygen intake pipes and magnetic feed lines are also placed here. The magnetic feed lines channel magnetic field energy to the door systems for operation during a power failure and the oxygen intake pipes channel filtered oxygen to the main environment processing bank. Scanner linkages visually carry data in a duplex (two way) fashion across the dimensional bridge.

In the event of the defensive mechanism shut-down, the TARDIS could suffer from fluid intake (water, waste gases, etc.) whilst landed and random energy or delta particle invasion whilst in flight. Note that the defensive mechanism is power backed by the power rod sub-circuit of the time vector generator.

ENTRY AND EXIT

Entry to the TARDIS is gained by use of a simple but unique key. The key identification is based on light refraction, so different keys refract different patterns of light onto the sensors. The lock is fitted such that only the exact kinds of keys will fit, and only the owner and companions of the operator may have those keys. Duplicates will be slightly different in design, requiring a different set of light gates to activate.

THE DOOR
The door exists in two different worlds, the normal dimension and a relative dimension. From the inside, the door's dimensions are 1.6m x .5m x .1m for each halve. The doors will look like the rest of the interior, complete with roundels. From the outside the doors can be any shape and size but no bigger than 1.6m x 1m. The doors, viewed from the real world, look like what the current entry form on the chameleon circuit is set to. The doors viewed from the interior look the same on the outside and on the inside. It is impossible to try and see both dimensions of the door, to do so results in only seeing the normal door if standing outside and the TARDIS door if standing on the outside. The forthcoming type 41 will be fitted with a void generator, which creates a null void between the interior doors and the exterior door(s). The doors then have their proper dimensions on both sides.

The passage between the interior and exterior dimensions is achieved by the permanent removal of limbo -- the fabric of space-time -- from that area. This process is done from the interior. The work of the void locker and dimensional integrator combine to achieve this effect. In essence, limbo separating the interior dimension from the primary spatial dimensions of the real world has been removed.

On closing the door from the outside, the doors from the inside are also closed, because they are in fact the same doors. When the door is locked on the outside, it closes the door switch in the interior of the TARDIS, having the same effect of closing the doors from the interior with the switch. When the doors are closed from the interior, from the outside it looks like the doors of the exterior shell (whatever they may look like) are closing by there own accord. When the doors close, the lock activates. The door can also be set to automatically close after exit, see below. The door itself contains the complex lock mechanism which is also described shortly below.

A feature unique to the mark III is called the seal cabin-to-interior door function. This utility switch will seal off the interior from the main control room. However, the interior access door must be closed for this procedure to work. This function cannot be cancelled elsewhere, i.e. it must be turned off before the door can be used again.

The mark III has several interior doors which can be activated via the central control console. Both the computer-bank alcove shutter and interior fire doors can be operated from the control room. The shutter, normally concealed, descends from the ceiling and prevents access to the computer bank area. The fire doors, on the other hand, are made of translucent aluminium, and will open and close when approached. The function of these doors is only to prevent the spread of toxic smoke and fire through the ship.

EXIT FROM THE INTERIOR

The door closing systems can be automated by the activation of the door mode selector switch. When all movement in the control room has ceased the doors will automatically close, this effect is observable from the exterior as well as the interior. If the automated systems are switched off then when the TARDIS door is being locked from the outside the user will have to manually close the doors before locking.
To leave the interior of the TARDIS simply flick the door switch down and up again. This will open the doors. Remember to do this only when landed, as opening the doors while in the space-time vortex is extremely hazardous. The switch will also close the doors from the interior, having the same effect as closing and locking the doors on the exterior of the TARDIS.

The door switch will close the doors if they are open, and will then subsequently open the doors is used again. If the doors are closed and locked then the door switch will unlock and open the doors. To both close and lock the doors the switch must be double-thrown, i.e. the switch must be flipped quickly and then put back into its original position. The lamp above the door switch illuminates when the door is unlocked and also flashes to confirm the process off locking and closing the door.

The emergency door-lock activate switch, a mark III function, locks the door opening mechanism so that the door may not be opened in flight. Very useful as accidental door opening can cause unpredictable problems.

The release main-door pressure switch, found on the mark II models, will unlock the doors but will not open them. The doors will open only if forced from the outside or pulled from the inside.

THE DOOR LOCKING MECHANISM

The door locking mechanism is the name given to the system that controls and operates the closing and locking of the main door. It has two input sources, the exterior keyhole access and the interior control panel switch. The interior has priority when two conflicting signals are sent to the door locking mechanism.

If the signal is sent for the door to be locked, from either the switch inside or the from a pulse from the light gates from within the lock, then the door is physically sealed at the atomic level. The atoms of the door edge combine with the atoms of the doorway edge, effectively enabling the door to now have the same physical attributes as the rest of the exterior shell. The door now is as strong as the rest of the exterior hull. There is the same chance of breaking in if someone bashed the door as if they bashed any other part of exterior shell. When a signal is given for the door to be unlocked, then the above process is reversed.

The door switch works through the use of an electromagnetic field manipulator, which generates and electromagnetic wave energy which is then channelled through the door hinges. The outer part of the hinges have an attraction to the inner part, and so the door opens, albeit slowly. The same principle is applied when the door is closed. In the event of a power failure the door can be opened as long as there is a magnetic field present outside the TARDIS. Providing there is sufficient magnetic induction, the field energy will be utilised and channelled to operate the door, ensuing that exit from the TARDIS is nearly always possible, even in the event of loosing power.

It is impossible to pick the main or secondary lock(s) of the TARDIS, because of the physical light refraction method. The object inserted into the keyhole must be the correct shape otherwise the wrong pattern of light is projected onto the sensors. It is not the actual movement of 'tumblers' that activate the lock, rather it is the physical shape of the key and the light patterns it makes whilst turning.

The door locking mechanism has a selection of working parts that have a potential difference applied across, these shield the end of the door lock mechanism and protect the inner parts from dirt, dust and intrusion. The latter deterrent works by electrocuting any thief who attempts to mechanically alter the locking mechanism. The applied potential difference is around 12 volts, but with a very small maximum current. Providing the thief is grounded (earthed/floor conducted), this will function as a painful deterrent but giving little permanent damage to the thief.

As a safety precaution the ship will not dematerialise with either the door left open, or the key left in the lock. This cannot be overridden from the inside, and is a permanent feature of the door locking mechanism.

THE TWENTY-ONE KEYHOLE CHOICE

The twenty-one keyhole choice is the name for the one of the security functions of the TARDIS. Its purpose is to deter a potential thief from opening the TARDIS if he has the key. The system works by giving the user of the key a choice of twenty-one keyholes to choose from. The extra keyholes are accessed by inserting the key into the normal lock and turning it around in a clockwise fashion. The whole lock will come away from the door, revealing a choice of twenty-one keyholes. Only one of these keyholes operate the second locking mechanism. If the key is inserted into the wrong keyhole then the lock will jam and the key will become stuck. This is known as the lockjammer effect.

The set of the twenty-one keyholes use the normal light refracting method of identifying the key or object inserted, similar to the light refraction method that the primary lock uses, although the second lot of locks require a more complicated set of light gates and transmitters to work.

Dealers on Gallifrey will inform pilots the factory set keyhole to use. This can be changed from the inside, and it is advised that this is done so, in case the someone connected with the TARDIS construction tries to steal a TARDIS. To change the correct keyhole to use the complete lock unit must be taken out. Behind the twenty-one keyholes, there is are two multi-spectrum light-gates, one on the vertical axis of the lock unit, and one on the horizontal. These line up to set the keyhole to be used.

THE LOCKJAMMER EFFECT

The lockjammer effect is simply when the lock will 'jam', i.e. it will not accept, release or allow any movement of the key. The lock could be just the primary keyhole, or it could be one of the Twenty-One keyholes. The lock and key are effectively jammed, both are now useless. The purpose of this effect is so that if any intruder tries to gain access to the TARDIS and he fails, he will not be able to try again. The downside of this effect is the fact that no-one can now enter the TARDIS, not even the proper owner.

The lockjammer device simply creates a low powered forcefield within the lock, by focusing the light beams through a small crystals. These light beams are usually used for identification of the key, but with amplification can be used to create a low powered force-field. The force-field ensures that the lock is impossible to activate.

If the locking mechanism becomes jammed or damage then the TARDIS must be taken back to Gallifrey for repair. Most of the locking mechanism repairs can be carried out by the owner of the TARDIS if he/she understands the principles of the lock. However, great knowledge of the individual locking system in required. If the TARDIS keys are stolen, the whole locking system must be realigned and reset, and new keys cut to fit the new lock. Note the if the key is stolen it may have been copied, and this allows the thief another chance to break in, thus violating Resolution 214 of Gallifreyian law, part A, Section One.

INTERIOR LAYOUT

Double doors give access to the living quarters and to the other interior rooms. All important rooms are outlined below.
Living Quarters There are six personal living areas with ample room for study, rest and sleeping. Sleeping bunks are provided. These rooms are connected to the central corridor.

Bathroom This large room contains a swimming bath, washing and changing facilities, multiple waste disposal systems and a personal hygiene sustainer unit. Soft Ultraviolet light permeates the area giving the pool area a special warmth and allows skin-tan to develop as well as helping the production of vitamin D.

Wardrobe A walk-in wardrobe equipped with space suits and many different styles of clothing ensure that any traveller will fit perfectly in with his surroundings as he travels from planet to planet.

Laboratory A multi-purpose scientific lab is provided and is stocked with standard apparatus and chemicals.

Power room This room houses the energy absorber, the energy converter, the starter pack and the flux automatic charger (FAC). A multitude of meters gives readings on power signal strength, sync pulse, energy flux, power output, current usage, base voltage, energy pulse reading, charge time, present energy charge, potential charge, energy recycled, emergency current drip, capacitor smoothing level, artron conversion ratio, artron power rate and energy storage amount.

Store rooms There are around ten different store rooms; some are empty and others contain minor spare parts for the TARDIS.

Sick bay A medical centre is provided in case the occurrence of injuries, sickness or travel fatigue, either with the personnel or pilot of the timeship. Several sleeping couches are fitted as is a comprehensive medicine cabinet.

Computer bank alcove The computer bank alcove contains a wall where the front panels of many computer banks can be seen. All of these machines connect up to the TARDIS central computer via the central data bus. The computer banks are described below.

Fault locator (1): If there is major problem in the TARDIS, such as a dematerialisation problem, then the fault should show up on the Fault Locator. The fault locator, when activated, starts a two dimensional line graph of the TARDIS systems, from A1 to Z9. The fault will appear as a peak in the graph at the particular point. The ID number is printed on the top of the paper. If the fault locator itself develops a fault then a large red bulb, situated on the front panel, will illuminate. While the lamp is lit, the fault locator will not operate..

The Astral Map (2): This computer bank can project three dimensional images of all the star systems in its databank. The controls are simple and the bank features an on/off switch, two running lights, a 2D viewer screen and a perspective controller.

Automatic Time Path Computer (3): Also known as the ATPC bank, this machine can convert raw time curve data (data stored by the TPR) into numerical time paths and coordinates that are then fed into the TARDIS's navigation system, via the TARDIS central data bus, so that a journey 'home' is ensured.

Time Path Recorder (4): This smaller computer bank complements the ATPC by recording the time paths taken in a journey, ensuring the possibility of returning to the original space-time position. It acts as a flight recorder and it stores all time paths and coordinates in number form in a hardware memory matrix. Coordinates, shown by bulbs, and time paths shown on a viewer screen, and a duplicate of the Time Vortex Indicator in the form of a meter, are among the features of this bank. The coordinates are destination only. An on/off switch and running lights complete the description of this machine.

THE INTERIOR DIMENSION

The inside of the TARDIS exists within a world relative to the exterior. This relative world exists in what has been called the fifth dimension. This section will attempt to explain the creation and sustaining of this fifth dimensional space.

Although the creation of the interior dimension was outlined in Section 1.4, the subject will be gone over again, with more attention being paid to the fundamental physics of the operation.

The theory of an artificial dimension is based on the fact that a dimension is anchored in place by means of a Natural Coordinate. This is a phenomenon thought to be connected with delta particles, an energy released when a delta particle changes its energy state.

The first step in extra-dimensional or transcendental space creation is to have a device which alters the coordinates of the fifth dimensional limbo barriers, the barriers which hold together the dimensions. The dimensional shifter is the circuit which does this function. The process is carried out by the creation of a limited electromagnetic field around a pre-defined space. The condensed field does not follow the standard event horizon rules concerning free space, as the field has only a small area of effect. this is achieved by bending the field back into itself, thereby confining the electromagnetic field area. The dimensional shifter only operates for around a nanosecond, and the distortion produced does not create a fifth dimension, rather it only shifts the position of the current normal space plane. Once the dimensional shifter operates another device operates to aid the dimensional shifter. The device is called the flux automatic charger (FAC).

The FAC increases the energy input to the dimensional shifter so that it can shift the current plane into the fifth dimension. Without the FAC boost, the dimensional shifter cannot generate a distortion strong enough to break the plane free from Natural Coordinate interference. After the successful operation of the FAC, a third circuit comes into play. The circuit, the dimensional control, generates a Natural Coordinate signal for the fifth dimension to lock onto. Without this NC signal, the fifth dimensional plane would slip back to normal space, being attracted to the NC. However, the fifth dimensional plane will not naturally home into the NC signal, rather it will hover around the NC area. To fine tune the fifth dimensional space, a circuit named the void locker operates. After the circuit has operated, a permanent artificial alternative dimension (PAAD) has been created.

In the event of local space distortion, the dimensional stabiliser may operate, to try and cancel out foreign signals which could mask the NC signal produced by the dimensional control.
