Abstract

PURPOSE:To secure powerful turning force with a simple structure, by attaching a jet engine, installing an injection pipe inside a drum part, to both sides to make it rotate around a center shaft, while transmitting a propulsion of the said engine to the center shaft, and converting it into turning force. CONSTITUTION:When a starting gear 22 is rotated by means of external power, a center shaft 1 rotates via a driving gear 19. And, a fuel feed pipe 11 attached tight to this center shaft 1 and a drum part 4 and a bottom part 15 of a jet engine are all rotated as one body. And, pressing force made by ram pressure is produced in an air intake 24 of an ar suction drum 6 whereby air circulates an injection pipe 5 and an exhaust drum 13. Thereupon, fuel is fed to an injection nozzle 12 via a feed hole, the feed pipe 11, and when ignition takes place with a spark plug 23, explosive force of combustion flows in the injection pipe 5 and the exhaust drum 13 and is spouted out. As a result, propulsion is produced there and thereby the center shaft 1 is speeded up in rotation, thus the turning force is taken out of the engine via an output side gear and an output shast 21.

Description

[Detailed description of the invention] The present invention relates to a rotary jet engine.

As is well known, many of the conventional jet engines were researched and developed for the purpose of making the aircraft equipped with the engine move in a straight line, making it possible for the aircraft to move a considerably heavy object in a straight line. Research on extracting engine output from the aircraft and using it for motive power other than aircraft movement;
The current situation is that it has not been developed. The present invention has been developed by researching such problems, and has developed a rotating engine that can transmit the large output of a jet engine to an output shaft outside the aircraft, convert it into rotational force, and use it as a variety of power sources with a simple structure. It was invented for the purpose of providing a type jet engine.

Reference numeral 7.7 denotes an air adjustment piece having a pointed cylindrical shape at the center of the inner diameter on the tip side of each air suction side 6. Reference numeral 8 denotes a fuel supply hole drilled inside the rotational center shaft 1 parallel to the longitudinal direction of the rotational shaft 1, and one end has a seal 9 (e.g. mechanical seal) l? It communicates with the fuel pressure pump 10 side, and the other end side is perforated to approximately the pot length position of the entire length of the rotation center shaft 1. Reference numerals 11 and 11 denote fuel supply pipes each having one end connected to the fuel supply hole 8 and the other end thereof bent and inserted into a position in front of the injection pipe 5 in the air intake side 6. 12.12...
is an injection nozzle attached to a portion inserted into the air suction side 6 of one end of the fuel supply pipe 11. 13, 13 are the rear end side (injection nozzle 12) of the body 4 of each jet engine.
It has a cylindrical shape for exhaust, with one end communicating with the other end (opposite end), and the other end bent downward to provide a downward exhaust hole 14. Reference numeral 15 denotes a rotary bottom surface extending laterally in the shape of a disk on the lower surface side of the body 4 of the jet engine. Reference numeral 16 denotes an exhaust surface provided below the rotating bottom surface 15 in the shape of a cylinder with a bottom, and an outer peripheral side surface 17 is provided close to the outside of the outer peripheral portion of the rotating bottom surface 15. Reference numeral 18 denotes an exhaust pipe which has one end communicating with the bottom side of the exhaust surface 16 and the other end bent toward the outside of the machine. 1
9 is a driving gear attached to the rotation center axis IK. 2o is an output side gear meshed with the driving gear 191C. 21 is an output shaft inserted into the output gear 20 and wedged therein.

22 is a starting gear meshed with the drive gear 19.

23 is a spark plug provided at a position in front of the injection pipe 5.

Since the present invention has such a configuration, the operation 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, and the rotation center As the shaft 1 rotates, the fuel supply pipe 11 fixed to the rotation center shaft 1, the engine support rod 3, and the jet engine body 4 and rotating bottom surface 15 fixed to the tip rotate as one. . Therefore, when the p momentum increases due to this rotation, an air pushing effect occurs in the air intake port 24 on the tip side of the air intake 6 by the ram, and the air with increased inflow pressure passes through the injection pipe 5. For exhaust 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, together with the air pushing effect, is ejected backward through each injection pipe 5.
Furthermore, since it is ejected along the exhaust gas 13, a strong propulsive force is generated, which rotates the rotation center axis l via the engine support rod 3.3, and this rotation is caused by the output side which meshes with the driving gear 19. It becomes possible to rotate the output '@21 through the 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, for exhaust 1
The exhaust gas ejected from the exhaust hole 14 is ejected into the exhaust surface 16 below the exhaust surface 16, and is further discharged to the outside of the machine from the exhaust pipe 18 provided below the exhaust surface 16. When the present invention is carried out in this way, the structure is simple and strong rotational force is generated by utilizing ram pressure and ejecting explosive gas from the ejection tube composed of a bundle of thin tubes and converting it into rotational force. This is the result of the present invention.
