(Function) Since the present invention has such a configuration, the function will be described next. First, starting is performed by applying a rotational force to the starting gear 22 from the outside, and when the driving gear 19 rotates, the rotation center shaft 1 rotates. However, due to the rotation of the rotation center shaft 1, the fuel supply pipe 11 fixed to the rotation center shaft 1, the engine support rod 3, and the jet engine body 4 and rotation bottom surface 15 fixed to the tip thereof are integrated. It rotates like this. Therefore, when the aircraft speed increases due to this rotation, an air pushing effect occurs at the air intake port 44 on the tip side of the air intake side 6 due to the ram pressure, and the air with increased inflow pressure passes through the injection pipe 5. and is discharged rearward from the exhaust cylinder 13.
In this state, the fuel is pumped into the fuel supply hole 8 by the fuel pump 10, the fuel is injected from the injection nozzle 12 through the fuel supply pipe 11, and the spark plug 23 is injected.
When ignited, the explosive force of the fuel is combined with the above-mentioned air pushing effect to inject backward through each injection pipe 5 and further along the exhaust shell 13, generating a strong propulsive force, which pushes the engine support rod 3, 3 to rotate the rotation center shaft 1, and this rotation is caused by the driving gear 1.
It is possible to rotate the output shaft 21 through the output side gear 20 that meshes with the output shaft 9 and the output side gear 20, and extract the rotational force to the outside of the machine. If the engine continues to rotate in this state, ram pressure is constantly generated in the air intake port 24, and the above-mentioned explosion stroke is made possible by fuel injection. Therefore, the exhaust gas ejected from the exhaust cylinder 13 is ejected into the exhaust box 16 below the exhaust hole 14. The high-temperature exhaust gas ejected into the exhaust box 16 passes through the exhaust passage gap 25 between the boilers 24 and 24 and further through the exhaust passage gap 27 between the boilers 26 and 26 inside the exhaust gas passage gap 25, heating the boilers 24 and 26. exhaust pipe 1
8 and is ejected from the aircraft. A part of the saturated steam generated in the boilers 24 and 26 is led out to the turbine 28 through the turbine steam outlet pipe 43, rotates the turbine 28 and is energized by the rotational force of the central rotation shaft 1, and then passes through the radiator 39 to the water tank. Return to 38. On the other hand, the saturated steam led out by the boiler 26 to the steam supply pipe 34 is transferred to the driving cylinder 29.
By alternately opening and closing a solenoid valve to the left and right of the piston 30 that slides, the piston 11 is assisted in sliding left and right, and the driving force of the crank and motor 32 is used to apply sliding force to the pushing rod 31 that slides left and right. Great help. As the push rod 31 slides left and right, the water supply piston 33 at the tip slides left and right inside the water supply cylinder 35, and the water in the water tank 38 flows into the water pumping pipe 3.
7 and enters the water supply cylinder 35, the water is pushed up by the water supply piston 33, passes through the water supply pipe 36, and is supplied into the boiler 24. Further, the steam discharged from the driving cylinder 29 is returned to the water tank 38 alternately on the left and right sides through the steam release pipe 41.

(Effects of the Invention) When carried out, the present invention utilizes ram pressure and blows out explosive gas from an ejection tube composed of a bundle of thin tubes, converting it into rotational force, so that a strong rotational force can be generated with a simple structure. In addition, the exhaust heat is converted to steam, and the power of the steam is used to rotate the turbine to assist the rotational force. Also, the steam using the exhaust heat can be effectively used in the supply device that supplies water to the boiler. This is an invention that makes it possible to utilize almost all of the energy contained in exhaust gas, such as thermal energy and velocity energy, for the rotational power of the engine.
