However, research into extracting the output of the jet engine outside the aircraft and using it as a motive force for purposes other than moving a single aircraft,
At present, there is almost no development. Therefore, the original invention of the present invention (Japanese Patent Application No. 139513/1982) focused on this point, and achieved the high output of a jet engine with a simple structure.

(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. When the driving gear 19 rotates, the rotation center shaft 1 rotates. However, due to the rotation of the rotation center axis 1, the fuel supply pipe 11. which is fixed to the rotation center axis 1. The engine support rod 3 and the jet engine body 4 and rotating bottom surface 15, which are fixed to the engine support rod 3, rotate together as one body. 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 6 due to the ram pressure, and the air with increased inflow pressure passes through the injection pipe 5 and is exhausted. Temperature 1
It is ejected to the rear from 3. In this state, fuel pressure pump 1
0, the fuel is pumped into the fuel supply hole 8, and the fuel is fed through the fuel supply pipe 1.
When fuel is injected from the injection nozzle 12 through the injection nozzle 1 and ignited by the spark plug 23, the explosive force of the fuel is ejected backward through each injection pipe 5, together with the above-mentioned air pushing effect.
Furthermore, since it is ejected along the exhaust temperature 13, a strong propulsive force is generated, which rotates the D rotation center shaft 1 via the engine support rods 3, 3, and this rotation generates an output that meshes with the driving gear 19. It becomes possible to rotate the output shaft 21 via the 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, exhaust temperature 1
The exhaust gas ejected from the exhaust hole 14 is ejected into the exhaust surface 16 below the exhaust hole 14. The high-temperature exhaust gas ejected into the exhaust surface 16 passes through the exhaust passage gap 25 between the boilers 24 and 24 and further inside the exhaust passage gap 2 between the boilers 26 and 26.
7 and is discharged outside the machine from the exhaust pipe 18 while heating the boilers 24 and 26. A part of the saturated steam generated in the boiler 24% boiler 2G is led out to the turbine 28 through the turbine steam outlet pipe 43, rotates the turbine 28 and is biased by the rotational force of the rotation center shaft 1, and is then transferred to the radiator 39. The entire water is passed through and returned to the water tank 38. On the other hand, the saturated steam led out from the boiler 26 into the steam supply pipe 34 is alternately supplied to the left and right sides of the piston 30 sliding in the drive cylinder 29 by opening and closing a solenoid valve, thereby assisting the left and right sliding of the piston 11. The sliding force of the push rod 31, which slides left and right by the driving force of the crank and motor 32, is greatly assisted.

As the push rod 31 slides left and right, the water supply piston 33 at the tip slides left and right in the water supply cylinder 35, and the water in the water tank 38 is drawn up from the water pumping pipe 37 and enters the water supply cylinder 35. Water is pushed up by the water supply piston 33 and is supplied into the boiler 24 through the water supply pipe 36. 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 the present invention is carried out, the structure is simplified and strong rotational force is achieved by utilizing ram pressure and further ejecting all of the explosive gas from the ejection pipe which is composed of a bundle of thin tubes and converting it into rotational force. obtained,
Furthermore, the exhaust heat is converted into steam, and the power of the steam is used to rotate the turbine to assist the rotational force.In addition, the steam using the exhaust heat can be effectively used in the supply device that supplies water to the boiler, and the exhaust gas is This invention makes it possible to utilize almost all of the energy possessed by the engine, such as thermal energy and velocity energy, for the rotational power of the engine.

4. The invention of Tokuhara No. 139513 of 1982, which is an additional related original invention, has a body of a jet engine composed of bundles of thin tubes placed on the left and right positions around the central axis of one revolution, and explosive gas is ejected from an ejection pipe. The main part of this invention is to provide the body of the jet engine at the left and right positions of the rotation center axis, but the present invention also includes jet engine jet engine bodies at the left and right positions of the rotation center axis. The main part is to provide the body of the engine, but the difference is that the exhaust gas is further guided to the boiler and saturated steam is generated to effectively utilize the exhaust energy. This invention has the same purpose as converting output into rotational force with a simple structure and using it as a various power source, and falls under Article 31, Item 1 of the Patent Law.
