Two integrated support structures 40 are disposed on opposite sides of the connecting portion 32 , and the housing 31 is located between the two integrated support structures 40 .

[0030] The integrated valve structure 30 and the integrated support structure 40 of the present invention are relatively integrated and miniaturized, and the integrated valve structure 30 and the integrated support str...

Embodiment 2

[0036] please continue to combine figure 2 , image 3 and Figure 6 Furthermore, the integrated support structure 40 includes a main body 41 and extensions 42 extending from the main body 41 to both ends, the main body 41 is fixedly connected to the connecting portion 32, the shell 31 is located between the two main bodies 41, and the extension 42 is arc-shaped, and the propulsion system 100 also includes two gas cylinders 50 arranged at both ends of the two integrated support structures 40 , and the two gas cylinders 50 are respectively fitted into the two pairs of extensions 42 at both ends of the integrated support structure 40 and fixedly arranged.

[0037] Specifically, the main body 41 and the connecting portion 32 are fixedly arranged, and the structural part of the main body 41 is hollowed out to reduce the weight of the integrated support structure 40. The integrated support structure 40 is an axisymmetric structure, which is more regular and beautiful. The shape o...

Embodiment 3

[0039] Please combine Figure 5 and Figure 7 Further, the extension part 42 includes an upper extension arm 421 and a lower extension arm 422, both of which are arc-shaped, and a gas cylinder strap 43 is connected between the upper extension arm 421 and the lower extension arm 422 , the gas cylinder strap 43 and the extension part 42 surround the gas cylinder 50 , and the gas cylinder strap 43 fixes the gas cylinder 50 to the extension part 42 .

[0040] Both the upper extension arm 421 and the lower extension arm 422 are arc-shaped to form an arc-shaped extension portion 42. The upper extension portion 42 first bends upward from the main body 41 to both ends of the integrated support structure 40, and then bends downward to form an arc. The lower extension part 42 fully extends below the integrated support structure 40 in an arc shape, so that the gas cylinder 50 and the extension part 42 can be in close contact to ensure the stability of the connection between the gas cyli...

Abstract

The invention is applicable to the field of aircraft bearing structures and provides a propulsion system. The propulsion system includes a storage tank, a connecting ring fixedly arranged at the bottom of the storage tank, an integrated valve structure fixedly connected with the connecting ring, and two integrated support structures fixedly connected with the integrated valve structure. The integrated valve structure includes a shell and a connecting portion extending outward from the edge of the shell, the connecting portion is fixedly connected with the connecting ring, two integrated support structures are arranged on opposite sides of the connecting portion, and the shell is located between the two integrated support structures. The integrated valve structure and integrated support structure are relatively integrated and miniaturized, and the integrated valve structure and integrated support structure constitute the main support of the propulsion system, reducing the length of the pipeline, the size of the outer envelope structure of the propulsion system and the weight of structural components. The weight and peripheral dimensions of the entire propulsion system are reduced to a certain extent. At the same time, the highly integrated propulsion system can reduce the coil workload in the final assembly process and reduce the production cost of the propulsion system.

Description

technical field [0001] The invention belongs to the field of aircraft load-bearing structures, and in particular relates to a propulsion system. Background technique [0002] Generally, the liquid propulsion system of an aircraft includes four major components such as gas cylinders, storage tanks, engines, and valves, and the connection between the above-mentioned components basically depends on pipelines, and the above-mentioned components are fixed by additional brackets to avoid shaking or even falling off For example, the engine is connected to the load-bearing cone or load-bearing plate through the engine frame, the gas cylinder and valve are connected together and fixed on the load-bearing plate through the bracket, and the gas cylinder, storage tank, engine and valve are connected by pipelines. The communication makes the aircraft liquid propulsion system a whole. [0003] If the overall structure of the aircraft liquid propulsion system cannot be coordinated to coor...
