Problems solved by technology

The disadvantage of this kind of engine is: since the accessories such as turbine, compressor and bearing are all moving components operating at high temperature, the processing technology requirements are extremely strict and complicated, and the manufacturing materials used are also very expensive, which greatly increases the Engine manufacturing cost and R&D and manufacturing cycle
In addition, since the intake velocity and pressure of this engine are constantly changing, the design and structure of the engine become very complicated, and further increase its manufacturing cost and R & D and manufacturing cycle.

Embodiment Construction

[0020] figure 1 In the piston engine, the pistons (1) and (2) in the piston engine are separated by a certain distance and fixedly connected in series; the sealed partition (3) between them divides the cylinder into two combustion chambers (4) and (5) and two There are two air compression chambers (6) and (7), and the pistons (1) and (2) move in opposite strokes; when the piston (2) performs suction and work strokes, it drives the piston (1) to exhaust and compress stroke and vice versa. When the pistons (1) and (2) of the piston engine do work, the air in the two air compression chambers (6) and (7) is continuously pressed into the air storage tank (9) through the check valve (8), and then passed through The valve (10) enters the combustion chamber (12), and is mixed with the fuel sprayed from the fuel nozzle (11) for combustion, and then sprayed out through the gas nozzle (13) to obtain power.

Abstract

The invention provides an air jet engine using a piston engine as an air compressor and application thereof. The air jet engine is characterized in that: by the motion of a piston in the piston engine, air entering an air cylinder is directly or indirectly compressed, and the compressed air and fuel are mixed and combusted in a combustion chamber and then jetted out from a jet pipe so as to generate a required propelling power. The piston engine and a ram jet are combined to form a ram pressure / piston jet engine. The gas jet pipes are arranged in all directions of an aircraft, so that the aircraft can obtain the abilities of vertical takeoff and landing, hovering and flexible turning. The gas is tangentially jetted by nozzles at the tail ends of aerovanes of the aircraft, so that the aerovanes can obtain higher rotary power and speed.

Description

technical field [0001] The present invention relates to an air jet engine and its application, specifically an air jet engine with a piston engine as a compressor and its application. Background technique [0002] We know that all air injection engines must compress the air before it can be mixed with fuel for combustion. Currently used air injection engines mainly include turbojet, turbine engines and ramjet engines. [0003] The compressor of the turbojet and turbine engine is a set of blades coaxial with the turbine, which rotates and compresses the incoming air and then enters the combustion chamber for mixed combustion with fuel, transforming chemical energy into heat energy to form high-temperature and high-pressure gas; high temperature and high pressure The gas first expands in the turbine to drive the turbine to rotate to drive the compressor; then the gas continues to expand in the nozzle to accelerate the gas and increase the speed of the gas so that the gas is e...
