 Self-Sealing Airship


When considering a major combat situation where troops and armoured vehicles are required on the battlefield as soon as possible after landing, the loading, exact positioning, and securing of heavy duty vehicles within the airship’s cargo bay, but especially tanks, or armoured vehicles is crucial to the deployment time at the drop zone. The payload area has been designed in shape of a “tunnel” in order to provide drive on - drive off, facilities in one straight line. This feature is further assisted by the positioning of unloading doors, at either end of the craft, ensuring that the maximum time for vehicle unloading is the time that it takes a vehicle to drive the hundred and sixty metres from the most central position, then down the ramps, and straight into the drop zone. 

The area designated to accommodate infantry troops, and other military personnel is located above the vehicle and equipment-holding area thus providing a protective feature consisting of two helium filled Kevlar-like composite strut floor panels, over which are placed reinforced floors of same material. The personnel have a choice, where they wish to go, and spend the flight time, but above all a means of reassurance that should the airship be hit from below, the equipment and material positioned below them shall provide an effective life saving measure in blocking most projectiles, even of smaller missile type, reaching them. 

Upon landing, they can either disembark together with their vehicles, depending upon whether they are tank crew, APC crew, truck drivers, etc., or if infantry, they can disembark straight from the craft on foot, via inflatable slides, or simply on the top of the exiting vehicles. In areas of extreme risk where speed is essential and surprise is paramount it is possible for the craft to land, the troops to enter their vehicles and the drop doors for each armoured vehicle to be disengaged totally upon actual contact with landing zone. These are “panels” located within the actual floor of the payload area that are put there initially for safety purposes where it may be decided to drop out a single tank, or an armoured vehicle to avoid disaster in emergency procedures, in an instance where every other protective and healing feature in the safety chain would fail. Another use of this system is that if one were to land directly in the mid of a battle zone under fire, the airship can unload all of its cargo within one millisecond upon touch down, take off in “jump” fashion, leaving the troops in their vehicles, on the ground, battle ready, from the first second of exposure.

The job of a designer of such craft is to provide multiple options so that the battlefield commander can then make his own choices from the selection available and take full advantage of any situation. One can only formulate strategy if one has at least some options.


The airship withstands not one, but even several missile hits. This defensive measure is achieved by the use of the segmental, and modular (patent pending) designs for the construction of the Hull. Even if all other defensive measures that autonomously guard the airship against missile hits, by performing various special manoeuvre sequences fail, this airship will survive several direct hits dependant upon the actual payload carried at the time of the impact. In such an instance, the self-sealing mechanism of the airship instantly kicks in and attempts to mend the damage, (for the time being), by sealing the orifices created in the hull. However, should this system fail, just as all the others, the safety system incorporates a simple design feature that permits ejection of one, or any chosen number of heavy load items, from the damaged sections, which instantly assists in counteracting the effects of damage caused, enables sustained flight, and permits safe passage towards any other desired location whereupon repairs are undertaken in a very short span of time, at worst by simply removing the damaged segment. 

The design of the airship evolved from the clear principle that in an instance where one is hit by a missile under an angle close to 45°, or 90° from either plane, is highly unlikely, therefore a same sided triangular cross section was taken as the best start out shape from which the final product evolved. This was in addition filled with torpedo-like inflated shapes that fulfil multiple functions, but above all create individual sealed units, parts of the total volume of the airship, of which most will always remain in absolute order, even if something as serious as a missile hit occurs. The same principle of course applies in the case of the chosen segmental design. 

Designed for military operations, the airship sensors, flight and telemetric systems, acting together with the counter acting ailerons (wings), and vectored thrust propulsion units, enable the airship to sense that a missile has been fired from a certain distance, which will eventually impact the craft in its front, mid, or rear section in a given span of time. Angle of approach is also taken into consideration, and automated defence systems override the manual input without informing the pilot that such operation is about to take place. The following theoretical sequence is then executed. While the airship was flying in a straight line at same flight level, at a speed of 150 km/hour the system sensors have noted a missile approaching and calculated the approximate hit area on the craft, the angle from which the missile will impact, and the approximate time remaining till impact in milliseconds. 

This calculation is then used to determine how much time will be required to execute the best from the range of available defence manoeuvres depending upon the exact position, angle, and velocity of the airship. The flight systems remain in standard flight mode, permitting the pilot to fly the airship as if nothing irregular was taking place, but shortly before the calculated impact the automated defence mode kicks in, and executes an instant evasive manoeuvre. This can be for instance any of the following special manoeuvres. The missile was going to hit the front section - the systems execute airship full stop at the same level, thus achieving that the missile has no time to redirect itself due to the apparent velocity difference of itself and the airship. The missile was going to hit the underside of the back section - the systems execute a full stop, and a 45 degrees turn around horizontal axis just before the impact is expected to take place. The missile passes by upwards. 

The airship is travelling at one level in a straight line, at maximum velocity, while a missile was fired from a fighter jet approaching at the same, or similar level. The missile was going to hit the back section of the airship under slight angle, causing maximum damage, as it would pass through many sections at once - the systems calculate its approach speed, time of impact, and approximate area of impact. Upon this, the automated defence systems execute a jump up one flight level, or down one flight level depending upon the calculated angle difference from horizontal mid cross section plane through the airship. This is achieved by using maximum output of the engines, and instant deflection, (upwards or downwards), of all four ailerons in an exact time sequence. Other preventative and defensive measures are also available, which reduce even more the likelihood of the craft being selected as a target - these are restricted to public.
