Embodiment Construction

[0054] The content of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0055] This embodiment is based on the general assembly layout of four machines, and provides a force transmission device with certain strength and rigidity, capable of withstanding a wide range of load changes, light in weight and high in efficiency, simple in structure and reliable in a limited space.

[0056] As the first-stage engine of the vertical take-off and landing reusable launch vehicle, a total of four engines with two large and two small engines are used to form a combined power. The engine installation is designed as a split frame, and the two large engines are fixed by the existing frame structure, and the two small engines with small height and thrust among the four machines are separately designed for power transmission; due to the large radial distance of the small engines, Each small engine is closer ...

Abstract

The invention provides a light-weight side wall hanging vertical force transmission frame and a first-stage engine, which solves the problem that the existing first-stage engine has a large difference in height and size between the large and small engines, which makes the frame redundant and the supporting components redundant; or occupies the cabin. segment space problem. The frame includes cross joints, 4 main joints, 4 connecting rods, the first I-beam, the second I-beam and 2 dowel bars; 4 connecting rods are connected by 4 main joints to form a rectangular frame; 4 The main joints are respectively the first, second, third and fourth main joints; the two ends of the first I-beam are respectively connected with the third main joint and the first interface of the cross joint; the two ends of the second I-beam are respectively connected with The fourth main joint and the second joint of the cross joint are connected; the connecting rod and the two I-beams form the first isosceles right-angled triangular frame, and the angle between the plane where the frame is located and the plane where the rectangular frame is located is 93°; 2 dowel bars One end of each is connected to the first and second main joints, and the other ends are connected to the cross joint.

Description

technical field [0001] The invention relates to the technology of a first-stage engine in a vertical take-off and landing and reusable rocket, in particular to a light-weight side wall hanging vertical force transmission frame and a first-stage engine. Background technique [0002] The frame is the basis of the layout of the first-stage engine assembly. It is the component that undertakes the connection, support and transmission of thrust between the engine and the rocket body. It also needs to bear bending moments and torques when the rocket body pitches, yaws, and rolls. The frame design principle of the first-stage engine requires simple structure, good manufacturability, open structure and strong bearing capacity. The frame frame is generally a truss-type structure, the upper and lower joints transmit force in parallel through the main load-bearing beam, and the auxiliary structure is welded by forgings or rods as a whole to relieve stress concentration or support.
