Description

The invention relates to the field of aerospace engineering and can be used when flying in the atmosphere and in space.

Known aircraft presented in patent No. 2363625, author Chasovskaya A.A. In it, fuel flows from the control unit into the combustion chamber. The control unit, the hydraulic output of which is in communication with the hydraulic input of the combustion chamber, issues commands for igniting portions of fuel. As a result, the pulsed outflows of the ignited fuel exit the combustion chamber. Two jet engines can be rigidly connected to the casing, with the help of which the initial movement of the apparatus begins. However, the magnitude of the acceleration may not always be sufficient.

Known aircraft, presented as a propulsion device in the patent No. 2532326, author Chasovskaya A.A. In it, unlike the aforementioned, two refractory spring valves are introduced, forming a shock absorber located inside a rectangular chamber, which can be represented as a rectangular chamber with a shock absorber inside, located inside the body.

In the initial state, the valves touch each other and do not pass fuel until it ignites. The shock absorber inside the rectangular chamber is hydraulically connected to the control unit. As the fuel is supplied from the control unit, ignitions occur at a frequency set by this unit. As a result, the spring valves are pressed against the walls of the rectangular chamber.

Repulsion of the body occurs when exposed to ignited fuel on the surface of the valves. Initially, the movement is due to the operation of jet engines rigidly connected to the body. Next, an increase in acceleration begins due to the excess of speed at the end of the body repulsion over the speed before repulsion, which is ensured by an increase in the kinetic energy during repulsion. This is explained by the fact that with the same push force of a moving object, its speed after the push will be the greater, the greater its speed before the push. However, the maximum speed is not always sufficient due to incomplete combustion of the fuel, which increases from push to push, and also due to a slowdown in the output of the ignited mass of fuel with an increased distance between the control unit and the place of fuel outflow. In addition, reliability decreases due to an increase in temperature at the locations of the valve springs.

Using the proposed device increases acceleration and reliability.

This is achieved through the use of a fuel delivery control unit with extended intervals of two refractory spring valves with heat-insulating gaskets and with turned curves at the end, as well as the placement of a rectangular chamber with a shock absorber inside behind the aforementioned control unit.

In the drawing and in the text, the following notation:

1 - housing.

2 - a control unit issuing fuel with extended intervals,

3 - a rectangular chamber with a shock absorber inside.

4, 5 - refractory spring valves with heat-insulating gaskets and rotated curves at the end.

6, 7 - jet engines.

In this case, the housing 1 is rigidly connected with two jet engines 6, 7, with a rectangular chamber with a shock absorber inside 3, with a control unit issuing fuel with extended intervals 2, hydraulically connected with the aforementioned chamber 3, which has refractory spring valves with heat-insulating gaskets and turned rounding at the end of 4, 5.

The device operates as follows.

In the initial period of time, the movement is carried out using jet engines 6, 7, rigidly connected to the housing 1. Next, fuel is supplied to the shock absorber inside the rectangular chamber 3 at longer intervals from the control unit 2. By commands from the control unit during the period of fuel receipt in the shock absorber of chamber 3 packs of ignited fuel are formed. Ignition in the shock absorber of the chamber 3 can be carried out by commands from the control unit 2 during the fuel delivery period by this unit. At the end of the interval, the movement of the body becomes uniform and then a pack is formed again and a new acceleration cycle is carried out. The amount of combustible fuel during pulse expiration can be stored at an increased frequency.

In the absence of ignition, the valves touch each other at the points of bending of the extremities. With a pulse outflow, the movement of the housing 1 relative to the spring valves 4, 5 occurs, which corresponds to the relative motion of two bodies relative to each other. This increases the speed during subsequent depreciation cycles. In addition, due to the rotated curvatures at the end of the valves 4, 5, they serve as the exhaust nozzle, and the surfaces of the extremities can be made in the form of ellipses. Reliability is ensured through the manufacture of valves made of refractory material and the presence of heat-insulating gaskets. The speed also increases due to the excess of the speed of movement at the end of repulsion over the speed of movement before repulsion. This is explained by the fact that with the same repulsive force, the speed of an object after repulsion depends on the speed before repulsion. However, as repulsions follow one after another, along with an increase in the speed of movement, the propagation speed of the mass of ignited fuel also increases in the direction opposite to the movement. In this regard, at the end of the pack of ignited fuel, the amount of unburned fuel increases, which reduces the efficiency. Therefore, in the shock absorber of chamber 3, by commands from the control unit, as already noted, bursts of ignited fuel are formed with elongated intervals between them. After each pack, a new acceleration cycle begins. Thus, a further increase in acceleration is carried out after the installation of uniform movement in each cycle, which reduces the amount of non-combustible fuel, and therefore increases the acceleration.

An option for continuous ignition between packs is possible. The acceleration also increases due to an increase in the speed of propagation of ignited fuel due to a decrease in the distance traveled by it due to the absence of an additional combustion chamber between a rectangular chamber with a shock absorber inside 3 and the control unit 2. A variant is possible with increased ignition frequencies when the valves are stationary and the amount of pressure can be adjusted.

Thus, the use of the proposed device increases the efficiency of aircraft. The device can be used in products with jet engines.
