Description

Technical Field

[0001] The present invention relates to an engine, in particular to a solid caseless rotating detonation engine, belonging to the technical field of aerospace engines. Background Art

[0002] A solid caseless rotating detonation engine refers to an engine that uses a caseless solid grain as fuel. The explosion pressure generated by the solid grain is much higher than the pressure generated by the fuel combustion. Therefore, its exhaust speed will be much higher than that of a traditional rocket engine, thereby achieving a working fluid specific impulse far higher than that of existing rocket engines.

[0003] In the existing technology, it is often only possible to achieve the impact explosion of a single propellant column and thus generate a certain thrust. However, as the weight of rocket engines becomes heavier, the explosive thrust generated by the existing technology cannot meet actual needs, that is, it cannot provide sufficient explosive thrust, which greatly affects the further development and use of rocket engines. Summary of the Invention

[0004] The object of the present invention is to provide a solid caseless rotating detonation engine in order to solve at least one of the above technical problems.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions: a solid caseless rotating detonation engine, comprising

[0006] A grain supply assembly is provided in the middle portion of the solid caseless rotating detonation engine and includes a plurality of grain rotating supply slots for holding caseless solid grains;

[0007] A charge pushing assembly is provided at the tail end of the charge supply assembly and is used to strike the tail end of the shellless solid charge to produce an explosion. The assembly comprises a pushing tool housing and a pushing plate movably provided within the pushing tool housing. The open end of the pushing tool housing is provided with a bottom plate. A rotating screw is connected to the center of the back side of the pushing plate. The other end of the rotating screw passes through the bottom plate and is engaged with a screw hole provided in the center of the rotating gear disc. The rotating gear disc and the bottom plate are coaxially rotatably connected. A spring is also provided between the pushing plate and the bottom plate.

[0008] The charge combustion assembly is arranged at the front end of the charge supply assembly and includes a combustion chamber fixing seat connected to the charge rotating supply groove and a combustion chamber fixedly connected to the combustion chamber fixing seat. The combustion chamber is arranged in a one-to-one correspondence with the shellless solid charge.

[0009] As a further solution of the present invention: the slots of the charge rotation supply groove are distributed in a ring shape, and the combustion chamber is connected to each slot of the charge rotation supply groove through a through hole opened in the combustion chamber fixing seat.

[0010] As a further solution of the present invention: a ring-shaped rack is provided on the outer periphery of the rotating gear disc, and the rack provided on the rotating gear disc is meshed with a driving gear sleeved on the front end of the driving shaft, and the driving shaft is connected to an external rotating device with a telescopic mechanism.

[0011] As a further solution of the present invention: the pushing tool shell is provided with perforations at the slots corresponding to the rotation supply slots of the drug column, and the pushing plate is connected with an impact push rod corresponding to each perforation.

[0012] As a further solution of the present invention, a limiting groove is provided on the periphery of the pushing tool shell, and a limiting block which is clamped in the limiting groove is connected to the outer periphery of the pushing plate.

[0013] As a further solution of the present invention, a pushing reset ring is provided around the outer shell of the pushing tool.

[0014] The beneficial effect of the present invention is that by setting a rotating supply groove for charge, it is possible to simultaneously impact multiple shellless solid charge, thereby generating an explosion. The gas detonation wave generated by the explosion of multiple shellless solid charge will be discharged through the combustion chamber, generating a large thrust, which can realize the propulsion of a large volume and weight rocket engine. In addition, the present application also has impact push rods connected to the pushing plate with perforations corresponding to the slots opened by the rotating supply groove for charge. When the pushing plate is pushed forward, each impact push rod can pass through the perforations and hit the shellless solid charge, thereby generating an explosion. A pushing reset ring is provided on the periphery of the pushing tooling shell, which can form a barrier to the forward push of the limit block, that is, it can ensure that the pushing plate is blocked when it is pushed to the position where it can hit the shellless solid charge, and then the limit block can be against the pushing reset ring after the spring returns to its original state, thereby realizing the reset of the pushing plate.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1

[0021] like Figures 1 to 3 As shown, a solid caseless rotating detonation engine includes

[0022] A charge supply assembly is provided in the middle portion of the solid caseless rotating detonation engine and includes a charge rotating supply trough 2 for holding the caseless solid charge 1, wherein a plurality of charge rotating supply troughs 2 are provided;

[0023] A charge pushing assembly is provided at the tail end of the charge supply assembly and is used to strike the tail end of the shellless solid charge 1 to produce an explosion. The assembly comprises a pushing tool housing 3 and a pushing plate 7 movably disposed within the pushing tool housing 3. A bottom plate 4 is provided at the open end of the pushing tool housing 3. A rotating screw 9 is connected to the center of the back side of the pushing plate 7. The other end of the rotating screw 9 passes through the bottom plate 4 and is engaged with a screw hole provided at the center of a rotating toothed disc 11. The rotating toothed disc 11 is coaxially rotatably connected to the bottom plate 4. A spring 10 is further provided between the pushing plate 7 and the bottom plate 4.

[0024] The charge combustion assembly is arranged at the front end of the charge supply assembly, and includes a combustion chamber fixing seat 15 connected to the charge rotating supply groove 2 and a combustion chamber 16 fixedly connected to the combustion chamber fixing seat 15. The combustion chamber 16 is arranged in a one-to-one correspondence with the shellless solid charge 1.

[0025] Example 2

[0026] In addition to all the technical features of the first embodiment, this embodiment also includes:

[0027] The slots of the charge rotating supply slot 2 are distributed in a ring shape, and the combustion chamber 16 is connected to each slot of the charge rotating supply slot 2 through the through-holes of the combustion chamber fixing seat 15, so that the shellless solid charge 1 placed in each slot of the charge rotating supply slot 2 corresponds to a combustion chamber 16, and the gas detonation wave generated by the explosion of the shellless solid charge 1 will be discharged through the combustion chamber 16 to generate thrust.

[0028] A ring-shaped rack is provided on the outer periphery of the rotating toothed disc 11, and the rack provided on the rotating toothed disc 11 is meshed with a driving gear 13 sleeved on the front end of the driving shaft 12. The driving shaft 12 is connected to an external rotating device with a telescopic mechanism. The driving shaft 12 is rotated by an external force to drive the rotating toothed disc 11 to rotate, so that the rotating screw 9 can be stretched outward, and the spring 10 is compressed to store elastic force, so that when the spring 10 is compressed to the maximum extent, the driving shaft 12 can be pulled out, and the pushing plate 7 can be pushed forward, thereby hitting the bottom of the shellless solid charge 1 and causing an explosion.

[0029] Example 3

[0030] In addition to all the technical features of the first embodiment, this embodiment also includes:

[0031] The pushing tool shell 3 is provided with a perforation at the slot corresponding to the rotation supply slot 2 of the charge, and the pushing plate 7 is connected to an impact push rod 14 corresponding to each perforation. When the pushing plate 7 is pushed forward, each impact push rod 14 can pass through the perforation and hit the shellless solid charge 1, thereby causing an explosion.

[0032] A limiting groove 5 is provided on the periphery of the pushing tool housing 3, and a limiting block 8 is connected to the outer periphery of the pushing plate 7 and is clamped in the limiting groove 5 to prevent the pushing plate 7 from rotating in the pushing tool housing 3, ensuring that the pushing plate 7 can only move in a straight line direction.

[0033] A push reset ring 6 is provided around the pushing tool shell 3, which can form a barrier to the forward push of the limit block 8, that is, it can ensure that the pushing plate 7 is blocked when it is pushed to the position where it can hit the shellless solid medicine column 1, and then the limit block 8 can be against the push reset ring 6 after the spring 10 returns to its original state, thereby realizing the reset of the pushing plate 7.

[0034] Working principle: The shellless solid charge 1 is pushed into the charge rotation supply slot 2 in sequence, and the drive shaft 12 is rotated by external force to drive the rotating gear disc 11 to rotate, thereby stretching the rotating screw 9 outward and compressing the spring 10 to store elastic force, so that when the spring 10 is compressed to the maximum extent, the drive shaft 12 can be pulled out, and the pushing plate 7 can be pushed forward, thereby hitting the bottom of the shellless solid charge 1. During the explosion process, the gas detonation wave generated by the explosion of the shellless solid charge 1 will be discharged through the combustion chamber 16 8 to generate thrust.
