Description

The invention relates to aerodrome technology, in particular to devices for taking off light combat aircraft such as carrier-based aircraft.

Known rotary take-off device containing pivotally mounted on a rotary tower cantilever metal with rails (UK Patent No. 1357976, F41F 3/04, 1974).

The disadvantage of this device is that it is impossible to use reusable starting boosters.

The objective of the invention is to develop the design of a rotary take-off device that eliminates these disadvantages and provides accelerated take-off (ejection) of aircraft from the shelter with virtually no take-off.

To solve the problem, a rotary take-off device is proposed, which contains a cantilever metal structure with guides pivotally mounted on a rotary tower.

The device is equipped for installation of the aircraft by a starter with a single pyro-charge, which is intended for acceleration with the connection of the aircraft engine along rails with a kink.

For takeoff, the aircraft is mounted on the starter, and the takeoff acceleration of the starter with the aircraft is carried out by double thrust - pyro-charge and the aircraft’s own engine.

With this acceleration, the speed of separation of the aircraft from the starter will be higher than the speed necessary for take-off from the GDP, and take-off will be carried out at a large angle with respect to the horizon.

The drawing schematically shows the proposed rotary take-off device, side view.

This device comprises a base with a rotary tower 1 and a folding console 2 hinged on the tower with guides including an acceleration segment 3 and a brake segment 4. A starter 5 is driven along the guides when the aircraft takes off, driven by a single charge. Inside the tower 1 there are mechanisms for turning the tower 1 and lifting the console 3, which are not shown in the drawing.

The rotary take-off device operates as follows.

In preparation for the take-off of aircraft, the device extends from the shelter, the console 2 is translated into working position (unfolds), rotates at the same time with the tower 1 in the direction of take-off and rises to the desired angle. Then the aircraft is rolled onto the starter 5, it is fixed with special locks, which are opened at the moment of the plane separation, a pyrocharge is installed in the special starter 5 socket equipped with a nozzle, and the device is ready for operation.

At the command “take-off”, the starter 5 with the aircraft accelerates with double thrust along the guides of section 3 and at the break of the guide sections 3 and 4, the plane breaks away from the starter 5 and takes off. The starter continues to move and is braked on the guides of section 4, and after stopping, it moves to its original position.

Take-off aircraft can be installed on starter 5 and with the landing gear retracted, which will reduce its drag.

This device can be used for dispersed basing in the shelters of individual units, consisting of three to five interceptor aircraft or light single-missile fighters with powerful missiles.
