Example Embodiment

[0053] Example one

[0054] Combine Figure 1-Figure 4 As shown, this embodiment provides an integrated two-component injector, including:

[0055] Fuel agent chamber 50;

[0056] The first bottom surface 10 is arranged at the bottom of the fuel cavity 50;

[0057] The second bottom surface 20 is arranged at the top of the fuel cavity 50 and opposite to the first bottom surface 10; and

[0058] At least one injection unit is provided in communication between the first bottom surface 10 and the second bottom surface 20;

[0059] The first bottom surface 10 and the second bottom surface 20 are both curved structures.

[0060] Preferably, the fuel agent cavity 50 is configured as a closed or partially open cavity structure, the bottom and top of which are respectively enclosed by a first bottom surface 10 and a second bottom surface 20, where the first bottom surface 10 and At least one injection unit is disposed between the second bottom surface 20, that is, the injection unit is disposed...

Example Embodiment

[0072] Example two

[0073] As for the integrated two-component injector described in the above embodiment, this embodiment will introduce in detail the injection unit arranged inside the integrated two-component injector on the basis of it.

[0074] Specifically, a number of injection units with different lengths are arranged between the first bottom surface 10 and the second bottom surface 20.

[0075] Since the fuel agent cavity 50 is provided with multiple injection units, the distribution form of the multiple injection units in the fuel agent cavity 50 may be honeycomb distribution, checkerboard distribution, concentric distribution, etc., In addition, the structure of the injection unit includes self-driving, mutual-driving, coaxial direct current, coaxial centrifugal, etc. Preferably, in this embodiment, the injection unit adopts a coaxial direct current injection unit.

[0076] This embodiment provides an integrated two-component injector. The injection unit arranged between ...

Example Embodiment

[0092] Example three

[0093] This embodiment provides a method for manufacturing an integrated two-component injector. The integrated two-component injector described in the first and second embodiments is manufactured by 3D printing.

[0094] The manufacturing method of the integrated two-component injector provided in this embodiment is made by 3D printing, which can reduce the development cost of the integrated two-component injector and improve product production efficiency. Relying on 3D printing technology, the three-bottom two-cavity injector structure and hundreds of injection units are printed together as an integral part, which greatly reduces the number of parts and reduces the product of the integrated two-component injector Cost; At the same time, the number of parts of the integrated two-component injector is integrated from hundreds into one, which improves the production efficiency of the product, greatly shortens the production cycle, and helps to improve the inhe...

Abstract

The invention relates to the technical field of space equipment, in particular to an integrated double-component injector, a manufacturing method thereof and the space equipment. The integrated double-component injector comprises a fuel agent cavity, a first bottom face arranged at the bottom of the fuel agent cavity, a second bottom face arranged on the top of the fuel agent cavity and opposite to the first bottom face and at least one injection unit communicating between the first bottom face and the second bottom face. The first bottom face and the second bottom face are of curved structures. According to the integrated double-component injector, the structural strength of the integrated double-component injector can be improved, the fuel agent cavity has the isostatic pressure flow equalizing characteristic, the flow of each injection unit is more uniformly distributed, and the injection combustion efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of aerospace equipment, in particular to an integrated dual-component injector, a manufacturing method thereof, and aerospace equipment. Background technique [0002] The injector is the core component of the liquid rocket engine. It is located at the head of the thrust chamber. Its function is to inject the propellant evenly into the combustion chamber under the specified propellant flow rate, mixing ratio and injection pressure drop to ensure mixing. The ratio and mass distribution meet the requirements of the design state, and the atomization and mixing process of the propellant are quickly completed, so that the propellant can be burned efficiently and fully in the combustion chamber. The design level and processing accuracy of the injector have a great influence on the stability, efficiency and life of the combustion chamber. Every percentage point lost in the efficiency of combustion through the injec...
