Description

Technical Field

[0001] This invention relates to the field of cross-medium engine technology, specifically to a gas-liquid dual-purpose intake structure and a cross-medium engine structure. Background Technology

[0002] Cross-medium aircraft are a new generation of flight devices that have attracted much attention. They can utilize the transformation of multiple flight modes such as underwater, water surface and air to achieve navigation in water-air medium, so as to perform multi-medium tasks such as cross-domain environmental monitoring and resource exploration. However, existing cross-medium engines have problems such as short travel distance, low underwater speed, limited air flight speed and slow cross-medium process. The key is that they are not equipped with a high-efficiency power system adapted to cross-medium operation.

[0003] In terms of new power units, the water reaction ramjet propulsion system is suitable for underwater jet propulsion. Since it does not need to carry oxidizer, it has excellent overall performance and a wide range of applications. The continuous rotating detonation engine is a new type of engine based on detonation combustion. It adopts an annular combustion chamber, and fuel and oxidizer are injected along the axis to achieve continuous detonation combustion. It has a compact structure and higher specific impulse and combustion efficiency compared with traditional turbine and ramjet engines.

[0004] Currently, the dual-purpose air intake structure and cross-medium engine structure are not convenient for multi-dimensional vibration reduction, which easily leads to vibration problems, causing the connection positions to loosen and resulting in engine failure. Summary of the Invention

At this time, the stress is concentrated on the second damping rod 15, which absorbs longitudinal stress. The third connecting rod 17, the fourth connecting rod 18, and the second docking block 19 at the bottom also cooperate in transmitting stress, which is concentrated on the second damping rod 15.

A docking block 28 is fixedly connected to the combustion chamber 24, and a separator sleeve 27 is fixedly connected to the docking block 28. A tapered dispersion head 26 is fixedly connected to the top of the separator sleeve 27. Through the structural design of the vibration damping starting structure 1, vibration damping is easily achieved. The support disc 5 and the support mating rod 6 are fixed to the outside. A first damping rod 8 and a docking ring block 9 are provided on the bearing ring sleeve 7. The connecting ring block 9 is inclined to absorb oblique stress, and the vibration damping mechanism 10 absorbs longitudinal stress.

At the same time, the connecting pipe 22, the conical duct 23, the combustion chamber 24, and the tail spray connecting pipe 25 are connected. The reactants enter through the connecting pipe 22 and reach the combustion chamber 24, where they are ignited and reacted, thereby driving the movement of the overall structure.

[0042] The connecting block 28 is a block design used to separate the space inside the combustion chamber 24 and the partition sleeve 27. The upper end of the connecting pipe 22 is connected to the intake structure 2, and there is a gap between the outer wall of the connecting pipe 22 and the support disc 5.

[0043] The docking limiting ring 20 is fixed in the middle of the combustion chamber 24, the second damping rod 15 is fixedly connected to the center of the docking ring block 9, and the first damping rod 8 is set at an angle.

The second damping rod 15, the second connecting rod 16, and the third connecting rod 17 form a triangular structure. The conical dispersion head 26 is set with a cone shape.

[0045] The dual-purpose gas-liquid intake structure 2 includes an atomizing water pipe 29, an oxidizer conduit 30, an intake channel 31, a first fuel conduit 32, a first control valve seat 33, a second control valve seat 34, and a second fuel conduit 35. Water vapor is introduced through the atomizing water pipe 29 and then guided into the intake channel 31. At this time, the vibration damping and starting structure 1 and the intake structure 2 are in an underwater position. Simultaneously, the first fuel conduit 32 is connected to the intake channel 31 through the first control valve seat 33, allowing the mixed reactants to reach the target area through the intake channel 31. The reactants are connected to the connecting pipe 22, then reach the conical conduit 23, and are guided into the combustion chamber 24. The reaction takes place in the combustion chamber 24, and flames are ejected through the tail nozzle connecting pipe 25 for propulsion. The reactants are dispersed by the conical dispersion head 26, reaching the gap between the separating sleeve 27 and the combustion chamber 24. The separating sleeve 27 separates the reactants into multiple segments, allowing for continuous reaction. The lower end of the atomizing water pipe 29 is connected to an air intake channel 31, and the lower end of the oxidizer conduit 30 is also connected to the air intake channel 31. The air intake channel 31 is connected to the first... A first fuel conduit 32 is connected to a control valve seat 33, and a second fuel conduit 35 is connected to the intake passage 31 via a second control valve seat 34. The lower end of the intake passage 31 is connected to a connecting pipe 22. Through the structural arrangement of the intake passage structure 2, dual-purpose gas-liquid processing is possible. The atomizing water pipe 29 and the oxidant conduit 30 are both connected to the intake passage 31. The first fuel conduit 32, the first control valve seat 33, the second control valve seat 34, and the second fuel conduit 35 are all connected to the intake passage 31, thereby enabling different processing. The reactants are guided through the intake channel 31 to the docking pipe 22, where they are then reacted in the combustion chamber 24, thus achieving channel sharing. When in the air, the oxidizer duct 30 introduces the reactants, which are then conducted through the intake channel 31. The second fuel duct 35 and the second control valve seat 34 introduce the oxides, which are then also introduced through the intake channel 31 to the docking pipe 22. The reactants then pass through the conical duct 23, the combustion chamber 24, and the tail nozzle 25 to perform the in-flight propulsion mission.

[0046] The working principle is as follows: During use, water vapor can be introduced through the atomizing water pipe 29 and then guided into the air intake channel 31. At this time, the vibration damping engine structure 1 and the air intake structure 2 are in an underwater position. At the same time, the first fuel conduit 32 is connected to the air intake channel 31 through the first control valve seat 33, so that the mixed reactants reach the docking pipe 22 through the air intake channel 31, and then reach the conical conduit 23, and are guided into the interior of the combustion chamber 24. The reaction takes place in the combustion chamber 24, and flames are sprayed through the tail nozzle connecting pipe 25 for propulsion. At this time, the reactants are dispersed by the conical dispersion head 26 and reach the gap between the partition sleeve 27 and the combustion chamber 24. The partition sleeve 27 divides the mixture into multiple segments, thereby enabling continuous reaction.

[0047] When in the air, the oxidizer duct 30 introduces the reactants, which are then conducted through the intake passage 31. The second fuel duct 35 and the second control valve seat 34 introduce the oxides, which are then also introduced through the intake passage 31 to the docking pipe 22. The oxides then react through the conical duct 23, the combustion chamber 24, and the tail nozzle pipe 25 to perform the aerial propulsion mission.

[0048] The user fixes the vibration damping structure 1 and the air intake structure 2 to the external housing via the support disc 5 and the support rod 6. The first damping rod 8, the docking ring block 9, and the second damping rod 15 are connected for limiting. When vibration occurs, the force is transmitted to the first connecting rod 13 through the first docking block 12. At the same time, the docking limiting ring sleeve 20 also transmits the force to the mating hinge block 21 and the second connecting rod 16. At this time, the stress is concentrated on the second damping rod 15, which absorbs longitudinal stress. The third connecting rod 17, the fourth connecting rod 18, and the second docking block 19 at the bottom also cooperate in transmitting stress, which is concentrated on the second damping rod 15. The second damping rod 15 is connected to the docking ring block 9. The first damping rod 8 is set at an angle to absorb stress at the angle. The first damping rod 8 is fixed to the support rod 6 via the bearing ring sleeve 7, which facilitates the connection and improves the stability of the connection, thereby improving the overall vibration damping capacity and completing the work.
