본 발명은 선체의 선미하부측에 위치하도록 추진축에 장치된 것으로서, 흡입구에서 분사구측으로 점차 단면적이 줄어들도록 전광후협한 압축분사실을 설치하고 압축분사실의 주벽에 고정장치한 1차, 2차, 3차 고정체와 추진축과 연동되게 일체로 고정시킨 1차, 2차 회전체를 교호하게 장치하되, 1차, 2차, 3차 고정체의 고정익을 물의 진입시 1차, 2차 회체의 추진각과 동일하게 유도설치하여 진입하는 물의 속도가 압축, 분사하는 1차, 2차 회전체의 회전 속도보다 빨라도 그 압축 및 가속이 가능토록 하였으며, 특히, 1차, 2차 고정체의 고정익 후면에 공기통로와 연통된 다수의 기공을 천공하여주므로 물진입과 1차, 2차 회전체의 회전에 의하여 생성되는 순간 진공화 현상에 의하여 부족 된 감압량 만큼의 공기를 흡입하게 하므로 연속 가속분사에 막대한 지장을 초래하는 압력의 단맥 현상을 방지하고 공기와 혼합된 물의 분사시 질량이 가벼워져 가속도가 높아지므로 높은 추진력을 얻을 수 있는 고속정용 분사추진 장치를 제공하는데 있다.The present invention is installed on the propulsion shaft to be located on the lower stern side of the hull, the primary, secondary, fixed to the circumferential wall of the compression injection chamber installed in the compression injection chamber so that the cross-sectional area is gradually reduced from the suction port to the injection port side Alternately install the primary and secondary rotors, which are integrally fixed to interlock with the tertiary stationary body and the propulsion shaft, with the propulsion angles of the primary and secondary bodies when the fixed wing of the primary, secondary and tertiary stationary bodies enters the water. Similarly, even if the speed of the incoming water is faster than the rotational speed of the primary and secondary rotors that are compressed and injected, the compression and acceleration are possible, and in particular, the air passage on the rear of the fixed wing of the primary and secondary fixtures. Because it punctures a number of pores in communication with the air, it inhales as much air as the decompression amount insufficient due to the instantaneous vacuumization phenomenon generated by water ingress and rotation of the primary and secondary rotors. Chapter is to prevent the development of pressure danmaek leading to and providing air and becomes a mass when the light water spray mixture for spraying hydrofoil that the acceleration is increased because the number to obtain a high thrust propulsion system.

종래의 분사추진 장치는 물만을 고압으로 압축하여 분사하는 방식으로 많은 동력을 소모하여 이를 압축시킨후 소경의 분사구로 분출시켜 추진력을 얻었던 것으로, 즉 F=ma(힘=질량×가속도)의 공식에서 나타낸 바와같이 스크류에 의한 추진력은 분사구의 물의 양과 물의 분사속도에 정비례함을 알 수 있다. 동일한 압력과 수량의 조건하에서 물을 가압분사할때 회전체에 의하여 압축분사실 내에 진공현상으로 인한 역압현상이 생성하므로 가속시 압력의 단맥현상이 발생되어 연속가압가속에 많은 지장을 받게 되는 등 많은 문제점이 있었다.Conventional injection propulsion device uses a large amount of power by compressing only water at high pressure, compresses it, and then ejects it to a small diameter injection hole to obtain a driving force, that is, in the formula of F = ma (force = mass × acceleration). As shown, the driving force by the screw is directly proportional to the amount of water in the injection port and the injection speed of the water. When water is pressurized under the same pressure and quantity conditions, a reverse pressure phenomenon is generated due to the vacuum phenomenon in the compression injection chamber by the rotating body. Therefore, short pressure phenomenon occurs during acceleration, which causes a lot of problems in continuous acceleration and acceleration. There was a problem.

본 발명은 종래의 문제점을 감안하여 안출된 것으로 1차, 2차 고정체의 고정익과 1차, 2차 회전체의 회전익 각도를 상호 대응시켜 물의 입사각과 추진각을 같게 하므로 저회전으로 가압가속이 가능토록 하고, 1차, 2차 회전체의 회전익 회전에 의한 순간 진공화 현상이 생성될 경우 그 가압된 양만큼의 공기를 1차, 2차 고정체의 고정익 후면기공으로부터 공기를 흡입하여 물과 혼합 분출하므로 "F=ma"의 공식에서 밝힌 바와같이 물의 비중을 가볍게 하여 물의 분사속도를 크게 하면 종래방식 보다 큰 힘을 얻을 수 있고, 물만을 압축하여 분사할 때와 같은 1차, 2차 회전체의 회전익에 의한 물의 큰 충격을 완화시킬 수 있으며 특히 2차 회전체의 회전익이 회전하면서, 고속분사하는 물을 직시하게 하여 추진력을 얻는 방법 등을 목적으로 한 공수 혼합 유도 연속 가속 분사추진 장치에 관한 것이다.The present invention has been devised in view of the conventional problems, so that the angle of incidence and propulsion of water are equal to each other so that the fixed blades of the primary and secondary fixed bodies and the rotor blade angles of the primary and secondary rotors correspond to each other, so that the pressurized acceleration is low. If possible, when instantaneous vacuum is generated by the rotor blade rotation of the primary and secondary rotors, the pressurized amount of air is sucked in from the fixed air rear pores of the primary and secondary fixtures. As the jet is mixed, as shown in the formula of "F = ma", if the specific gravity of water is increased to increase the injection speed of water, a greater force can be obtained than the conventional method. It is possible to alleviate the big impact of the water by the whole rotor blade, and the airborne mixing induction continuous for the purpose of obtaining the propulsion force by facing the water sprayed at high speed while the rotor blade of the secondary rotor rotates. An acceleration jet propulsion apparatus is provided.

본 발명은 첨부 도면에 의하여 보다 구체적으로 설명하면 다음과 같다.The present invention will be described in more detail with reference to the accompanying drawings.

즉 제1도에 도시한 바와 같이 선체(15a)의 후미 하부에 부착하여, 선체(15a)가 물속으로 1/3가량 잠겨 있는 상태로 하고, 선체(15a)의 엔진을 작동시키면 통상과 같이 추진축(15)이 구동하여 본 발명의 1차, 2차 회전체(3)(7)가 회전하면서 제2도에 도시한 바와 같이 물이 전면 흡입구(18)로부터 압축분사실(17) 내로 진입하게 되는바, 이때 진입된 물은 먼저 물의 입사각과 동일각으로 장착된 1차 고정체(1)의 고정익(2)에 의하여 저항없이 진입하게 된다.That is, as shown in FIG. 1, when it is attached to the lower lower part of the hull 15a, the hull 15a is submerged in water for about one third, and the engine of the hull 15a is operated, the propulsion shaft as usual. (15) is driven to rotate the primary and secondary rotors (3) and (7) of the present invention so that water enters the compression injection chamber (17) from the front suction port (18) as shown in FIG. At this time, the entered water is first entered without resistance by the fixed blades 2 of the primary fixed body 1 mounted at the same angle as the incident angle of the water.

일단 1차 고정체(1)의 고정익(2)에 진입된 물을 상기 고정익(2)에 의하여 1차 회전체의 추진각과 같게 유도하여 1차 회전체(3)에 의하여 회전익(4)을 가압, 가속 회전시키면서 다시 2차 고정체(5)의 고정익(6)측으로 가압 분사하게 되며 이는 다시 2차 회전체의 회전익(8)을 가압, 가속시키면서 3차 고정체(9)의 고정익(10)으로 고속 분사하게 되나, 3차 고정체(9)의 고정익(10)을 통과한 진입된 물은 고압축 되고 고속 분사하여 소경의 분사구(11)를 통해 직사 방출하게 되므로 선체(15a)는 높은 추진력을 얻게 되는 것이다.Once the water enters the fixed blade 2 of the primary fixed body 1, the fixed blade 2 is guided by the same as the propulsion angle of the primary rotating body to press the rotary blades 4 by the primary rotating body 3 While pressing and spraying to the fixed blade 6 side of the secondary stator 5 again while accelerating rotation, this again pressurizes and accelerates the rotary blade 8 of the secondary stator body 10 of the third stator 9. High speed injection, but the water entered through the fixed blade 10 of the tertiary fixed body (9) is high compression and high-speed injection is discharged directly through the small diameter injection port 11, the hull (15a) has a high propulsion force You will get

즉 이와 같이 높은 추진력을 얻게되는 과정에서 해결하는 문제점을 다시 설명하면, 선체(15a)의 엔진 작동에 의해 추진축(15)이 구동을 하게되어, 1차, 2차 회전체(3)(7)의 회전익(4)(8)이 회전을 하면서 물이 흡입구(18)를 통해 압축분사실(17)로 진입을 하게 되는바, 이때 압축분사실(17)의 입구는 넓고 후미 분사구(11)측은 좁게 전광후협하게 되어있어 일단 진입된 물은 그 흐름에 따라 자연히 압축이 되게 되며 1차 고정체(1)의 고정익(2)을 통과하면서 1차 회전체(3)의 회전익(4)을 가압하면서 가속으로 회전시키는데, 이는 1차 고정체(1)의 고정익(2)이 물의 진입각과 같은 각이고 그 선단이 회전체(3)의 추진각과 동일하게 되어있어 거의 저항없이 1차 회전체(3)의 회전익(4)를 화살표 방향으로 가압, 가속회전 시킨다.In other words, the problem to be solved in the process of obtaining a high propulsion force is described again, the driving shaft 15 is driven by the engine operation of the hull (15a), the primary, secondary rotors (3) (7) The rotor blades (4) (8) is rotated while the water enters the compression injection chamber (17) through the suction port 18, wherein the inlet of the compression injection chamber 17 is wide and the rear injection port (11) side It is narrowly all-in-one coarse, so that the water once entered is naturally compressed according to the flow, while passing through the fixed blades 2 of the primary stator 1 while pressing the rotor blades 4 of the primary rotor 3. It rotates with acceleration, which means that the fixed blade 2 of the primary stator 1 is at the same angle as the entry angle of water and its tip is the same as the propulsion angle of the rotor 3 so that the primary rotor 3 is almost without resistance. Press the rotor blades 4 in the direction of the arrow to accelerate the rotation.

이때 회전체(3)의 회전익(4)이 회전을 하게되면 그 회전체(3)의 전면에 진공화 현상이 생성되어 회전익(4)의 회전을 방해하는 역압현상이 일어나게 되나, 1차 고저(1)의 고정익(2) 후면에 다수의 기공(12)이 천공되어 있고 이 기공(12)은 공기통로(13)와 연통되어 있어 그 감압된 양만큼의 부족 공기(14)만을 공급하게 되므로 순간적인 진공화 현상에 의한 단맥 현상을 방지할 수 있어 진입된 물은 분사구(11)측으로 회전하면서 가압, 가속되는 것이다.At this time, when the rotor blade 4 of the rotor 3 rotates, a vacuuming phenomenon is generated on the front of the rotor 3, and a back pressure phenomenon that hinders the rotation of the rotor blade 4 occurs, but the first height ( A plurality of pores 12 are perforated in the rear of the fixed blade 2 of 1) and the pores 12 communicate with the air passages 13 to supply only the depressed air 14 as much as the reduced pressure. The short-circuit phenomenon due to the general vacuuming phenomenon can be prevented, so that the water entered is pressurized and accelerated while rotating toward the injection hole 11.

이와 같은 방법으로 다시 2차 고정체(5)의 고정익(6)을 통해 2차 회전체(7)의 회전익(8)을 가압, 가속회전을 시켜주고 2차 회전체(7)의 회전익(8)이 회전하면서 생성된 진공화 현상은 1차 작동시와 같이 2차 회전체(7)의 회전익 후면 기공(12a)을 통해 공기통로(13a)의 공기(14)를 분출시켜 진입된 물과 혼합된 후 3차 고정체(9)의 고정익(10)에 의하여 직사 방출토록 되는 것이다.In this manner, the rotor blade 8 of the secondary rotor 7 is pressurized and accelerated again through the fixed blade 6 of the secondary stator 5 and the rotor blade 8 of the secondary rotor 7 is accelerated. The vacuuming phenomenon generated by rotating) is mixed with the water entered by blowing the air 14 of the air passage 13a through the rear pore 12a of the rotor blade 7 of the secondary rotor 7 as in the first operation. After it is to be discharged directly by the fixed blade 10 of the third fixed body (9).

상술한 바와 같이 본 발명은 전광후협한 압축분사실(17)내에 상호대응하여 고정익(2)(6)(10)과 회전익(4)(8)을 회전체(3)(7)의 추진각과 동일하게 하고 고정체(1)(5)(9)와 회전체(3)(7)를 교호하게 설치하되, 고정체(1)(5)(9)는 압축분사실(17)의 내주벽에 고착시키고, 회전체(3)(7)는 추진축(15)에 장착하여 연통되게 하였으며, 1차, 2차 고정체(1)(5)의 고정익(2)(6) 후면에는 공기통로(13)(13a)와 연통된 기공(12)(12a)를 다수 천공하여서 된 것으로, 압축분사실(17) 내로 투입된 물은 고정체(1)(5)(9)의 고정익(2)(6)(10)에 의하여 높은 추진력을 얻을 수 있고, 특히 작동시 진공 상태에 의한 감압현상시 고정익(2)(6)의 기공(12)(12a)에 의해 공기(14)를 상태에 따라 공급되게 하여 물과 혼합이 가능하므로 비중이 가볍고, 탄력이 있는 물은 좁은 분사구(11) 쪽으로 더욱더 팽창 가속하면서 초고속으로 직사 분사 할 수 있는 매우 획기적인 발명이다.As described above, the present invention corresponds to the propeller angles 2, 6, 10 and the rotor blades 4, 8 of the rotating body 3, 7 in correspondence with each other in the compression-optical chamber 17, which is all-optical and narrow. In the same manner, the fixing bodies 1, 5, 9 and the rotating bodies 3, 7 are alternately installed, and the fixing bodies 1, 5, 9 are inner circumferential walls of the compression injection chamber 17. The rotor 3 and 7 are mounted on the propulsion shaft 15 so as to communicate with each other, and the air passages are provided on the rear of the fixed blades 2 and 6 of the primary and secondary fixtures 1 and 5. 13) It is made by drilling a plurality of pores (12) (12a) in communication with (13a), the water introduced into the compression injection chamber 17 is fixed blades (2) (6) of the stationary (1) (5) (9) 10, high propulsion force can be obtained, and in particular, the air 14 can be supplied according to the state by the pores 12 and 12a of the fixed blades 2 and 6 during the decompression under vacuum. It is possible to mix with water, so the specific gravity is light, and the elastic water is accelerated to expand even more toward the narrow nozzle (11) It is a very innovative invention to direct injection into.
