DE3430101A1 - Landing and take-off carriage - especially an emergency landing carriage - for aircraft - Google Patents

Abstract

A take-off and landing aid for aircraft, especially a landing aid in emergency situations, can be provided in that a carriage which runs on rails on the runway - optionally - also on wheels is accelerated so greatly that it precisely reaches the speed of the landing aircraft, and the aircraft then sets down on the carriage, any non-uniform setting down which may occur in emergencies being compensated for. In this case, the aircraft is anchored on the carriage, and the carriage is braked so that it can subsequently leave the carriage. Adjustable supporting and holding devices are fitted on the carriage cover, which devices are aligned to the characteristics of the individual aircraft type. This applies just as much to the devices which are present on the carriage for emergency and catastrophe cases: water and chemical extinguishing means, air bags, apparatuses for forced entry into the cabin, rescue apparatus for emergency evacuation etc. By means of additional apparatuses, fog can be dispersed, snow cleared from the runway, and specific aircraft types can be refuelled and loaded automatically. The carriage remains fully serviceable for carrying out landings and take-offs even when the runway and/or weather conditions existing are completely unsuitable for taking off or landing otherwise. In the event of emergency landings, catastrophic consequences can under some circumstances be effectively reduced or completely prevented. Overall, a considerable reduction in the danger risk may result.

Description

Landing and take-off vehicles - especially emergency landing vehicles - for aircraft :

In an emergency, a plug stuff can during as well
often only a little or immediately after landing
no sustainable, effective help can be provided.

The ability to take a plane while as well
Immediately after landing, possibly lasting help
being able to grant is brought about by the fact that
a car on the runway like this
is strongly accelerated until it has reached the same speed as the landing plug stuff. That
The plug-in item sits on the wagon and is automatically [ anchored in such a way that the braking process can be carried out by the landing vehicle ':, and then the plug-in item from
lower the car or - can be pulled down in an emergency. This assistance
can e.g. in difficult weather conditions'"

Conditions, especially during emergency landings, '-, but also generally given during landings and take-offs ' ·. will.

Because of the continuity in terms of change; the approach speed is given, it is necessary that the car is exactly the speed
of the landing plug stuff. The torment adjustment
can be done by moving the raised platforms on the wagon, on which the wheels of the plug tool sit, the platforms moving in the direction of travel
If necessary, however, can also be moved sideways. The pedestals are on the wagon anyway with a view to adapting "
the position of the various units of the wagon to the [ different plug stuff types adjustable.
There will also be uneven loads on the
individual pedestals thanks to the ^: wheels of the plug-in display using an ABS process analogous to that
applied system optimally balanced. All in all
it is thus possible to shape the load on the car caused by the landing of the plug stuff _; that the stress of the device is minimized as well as the plug-finished product, the car is equipped such that substantial \ measures for combating the consequences of accidents
are required to be carried out immediately
can - as soon as the aircraft is in the carriage area; comes or touches or - in an emergency - _r has been "captured" or has landed on the car I.

The car is designed as a hybrid vehicle -, - He \ will initially run continuously by means of rollers on rails, '": the embarked on the car side in manholes, are that can be crossed addition possesses.
the car had a larger number of tires fitted
Wheels., So that - after separation from the rail rollers, it is also possible to drive on the unpaved airport site - even for short distances at high speed. The wheels can be rotated up to 90 ° in order to be able to move sideways from the runway, turn around: 180 around your own axis, and so on.

The car's electric motors are powered by busbars, which are housed in the shafts. The car also has accumulators, to maneuver on the Plughafenge land and to carry out a flight in the event of a power failure to be able to «They can also be used for the energetic utilization of the braking forces« The wager is controlled by the computer built into the wagon or - as required by the Tower of the plug port e.g. from or - optionally from the incoming plug stuff. A radar device housed in the van measures the distances only to those who are hesitant Plugzeug and forwards the data to the Oompxiter built into the car - Pahrtberinn and The speed of the car is determined with it. A high one that was movable on the wagon The sensor bar makes body contact with the plug-in tool before it even touches down moves with the incoming plane on the Car forward. This enables a new determination of the height of the plugzetigs, the precise control of the Car speed, the time of touchdown etc. possible or recognizable. These things will be processed by the computer and communicated to the PiIoI s. These data, which are important for the pilots, as well as data that, in emergency situations, e.g. about behavior individual undercarriages are of importance, are clearly visible to them at the front of the goods, e.g. by means of light bars that show the respective situation by changing the color, by means of an LCD display and others | expelled.

are aligned with the individual plug type. The car is equipped so that after entering of the plug-in item type in the computer built into the car, a corresponding alignment of the units of the Car takes place. The plug-in type entered is clearly recognizable by pilots from a distance E.g. LCD display and communicated by dot. The landing of the plug stuff on the wagon that was in the The rail and wheel area is cushioned, initially takes place separately for the individual chassis provided, inclined and arranged according to the conditions of the individual plug stuff type Platforms raised above the car deck, e.g. by means of an oil pressure jack, which. after sitting up of the aircraft on the pedestals immediately ^ enkcu to ir. dem WagendecJ: plan introduced r.u to be, v / omii; at the same time the complete anchoring of the plug equipment on the wagon deck has been completed.

By lowering the thin platforms accordingly, e.g.

an uneven landing of the landing gear caused by emergency situations or if a landing gear fails, the aircraft is balanced v / earth. For the nose wheel is one:

comparable equipment available.

Extendable telescopic supports attached to the trolley, from the computer according to the circumstances of the individual aircraft type are moved into the position required for the application, are partly like this with each other tense so that, for example, it is also possible to catch the trunk at a certain point.

The car is equipped with the following facilities for emergencies or disasters, which also - if necessary - the local conditions of the individual aircraft type adjust:

1. Water and chemical extinguishing agents are available in storage tanks. You own but also a direct connection via the rail shafts sunk into the ground, whereby A decrease can be made by the carriage over the entire length of the rail line. 2, fire-proof airbags - distributed over the car deck - allow certain To deal with hot situations, e.g. if the whole Landing gear could not be extended. 3. By the possibility of forcible separation of a vehicle part, the further spread of a fire can be prevented, for example. 4. With devices for forced entry that are precisely tailored to the type of aircraft The window in the interior room can be a first aid, e.g. a supply of oxygen are given.

A technical facility makes this possible forcible opening of the cabin from the outside. 6. There are facilities on the wagon for the pick up the people who have to get off the aircraft.

Luiter can use additional equipment on the trolley, in some cases chemical or physical processes are precipitated over the runway fog or Snow must be cleared from the runway. Landings and take-offs are - especially at the ride on wheels - possible on not completely straight tracks. Can on the wagon a jump start must also be installed.
