Abstract

FIELD: aero-space engineering; flying vehicles for flights in atmosphere and in space.

SUBSTANCE: proposed flying vehicle has cylinder with piston located inside it, jet engine rigidly connected with piston and body. Body is rigidly connected with ignitable fuel damper for mutual repulsion of engine and piston. Damper is hydraulically communicated with damper control unit. Body is rigidly connected with cylinder provided with two exhaust pipes for escape of exhaust gases and two safety stops at the end for preventing the piston from extending from cylinder. Flying vehicle is also equipped with jump-wise shifting conveyer for delivery of capsules filled with explosive to damper. Conveyer is located in recess in body and is provided with swivel spring-loaded valve. Valve is turned by means of front capsule found on conveyer. Detonation of capsules takes place due to their ignition by gases of ignitable fuel.

EFFECT: reduced consumption of fuel.

Description

The invention relates to aerospace engineering and, in particular, to propulsion systems of aircraft (LA) for flights in the atmosphere and space.

Known LA Pat. RU 2270143 C1 (Chasovskoy A.A.), which contains a housing, shock absorbers with a control unit for them, jet engines located behind the shock absorbers, exhaust nozzles and pipes.

Known LA Pat. RU 2134218 C1 (Chasovskoy A.A.), adopted for the prototype. This aircraft contains a cylinder with a piston located inside it, a jet engine rigidly connected to the piston and a housing rigidly connected to a shock absorber of flammable fuel for mutual repulsion of the housing and the piston hydraulically in communication with the control unit of this shock absorber, and the housing is also rigidly connected to a cylinder having two exhaust pipes for exhaust gases and safety stops provided at the end to prevent the piston from leaving the cylinder.

To achieve high flight speeds of a known aircraft, a significant amount of fuel is required.

The objective of the invention is to reduce the amount of fuel required for the flight of the aircraft.

This problem is solved in that a jump-shifting conveyor is introduced into the apparatus for moving capsules with explosives into the shock absorber, located in the recess of the casing and equipped with a rotary spring valve, the rotation of which is made by the front capsule behind it on the conveyor.

The invention is illustrated by the attached drawing, which adopted the following notation:

1 - housing;

2 - shock absorber control unit;

3 - recess in the housing;

4 - stepwise shifting conveyor for movement into the shock absorber capsules with explosives;

5 - front capsule on the conveyor;

6 - shock absorber;

7 - rotary spring valve;

8, 9 - exhaust pipes;

10 - a piston;

11 - jet engine;

12 - cylinder;

13, 14 - safety stops.

The aircraft contains a jet engine 11, rigidly connected to the piston 10 inside the cylinder 12. The shock absorber 6 is in fluid communication with the shock absorber control unit 2 and is rigidly connected to the housing 1. Exhaust pipes 8, 9 are connected to the cylinder 12. Safety stops 13, 14 prevent the piston from exiting 10 from cylinder 12.

The jump-like conveyor 4 is equipped with a rotary spring valve 7, behind which is located the front capsule 5 (of all other capsules on the conveyor). The capsule shells are made of a combustible substance. The closed valve 7 is pressed against the front inner wall of the shock absorber 6. The outer surface of the valve 7 is made of refractory material.

The device operates as follows.

In the initial state, the piston 10 is adjacent to the housing 1. The movement of the aircraft is carried out traditionally due to the thrust of the jet engine 11.

After reaching a certain speed and altitude of the aircraft using the control unit 2, the gases in the shock absorber 6 are ignited. The necessary metered amount of fuel is delivered to the shock absorber in advance. Exhaust gases exit through the exhaust pipes 8, 9.

After repulsion of the piston, the conveyor 4 with capsules makes their jump-wise movement one after another.

In this case, the front capsule 5 rotates the rotary spring valve 7 and enters the shock absorber 6, after which the valve 7, thanks to the spring, is again pressed against the front wall of the shock absorber 6. There are protrusions in the conveyor protecting one capsule from the other.

At the same time, the piston 10, in connection with the operation of the jet engine 11, stops moving in the opposite direction and begins to move towards the shock absorber 6.

By the moment the piston 10 enters the shock absorber 6, the explosive in the capsule detonates due to the ignition of the shell from the gases ignited by the shock absorber 2. After detonation, the housing 1 and the piston 10 with the jet engine 11 are repelled in opposite directions and the exhaust gases exit through the exhaust pipes 8 , 9.

With a certain selection of fuel and explosive in capsules, the amount of fuel necessary to repel the piston from the apparatus body at a given speed can be reduced. The higher this speed, the more efficient the use of a jet engine 11 with a limited own specific impulse.

Further depreciation cycles follow each other, providing an increase in the acceleration and speed of the aircraft.

After reaching a predetermined flight speed, the shock absorber control unit 2 ceases to deliver fuel to the shock absorber 6, and the jump-shifting conveyor 4 with capsules stops working. If braking is necessary, the device must turn 180 ° and repeat the above depreciation cycles.

In the proposed apparatus for increasing acceleration, the amount of fuel for igniting the shock absorber gases can be reduced. Moreover, the explosive in capsules may have a smaller volume and mass than the additional fuel necessary for such an increase in acceleration. In this regard, the time to spacewalk and other flight operations can be reduced.
