Rocket engine support

Abstract

The invention relates to a rocket engine support which comprises a hollow support body and further comprises reinforcing assemblies which are symmetrically and integrally formed and fixedly connectedon the outer side of the support body, and an opening allowing an engine to be embedded is arranged in the support body. Each reinforcing assembly comprises a plurality of first reinforcing blocks fixedly connected to the edges of the two sides of the face, away from the opening, of the support body, and a plurality of reinforcing plates integrally formed and fixedly connected to the two sides ofthe support body. The first reinforcing blocks and the reinforcing plates improve the impact deformation resistance of the support body and improve the structural strength of the support body. Furthermore, the first reinforcing blocks and the reinforcing plates are fixed on the outer side of the support body, the contact area between the support body and the rocket body is reduced to a large extent when the support body is installed, the transmission path of vibration energy generated when the rocket engine works is shortened, and thus vibration generated when the rocket body lifts off is reduced, the stability of the rocket in the flying process is improved and the rocket is not liable to deviating from the expected running track.

Description

technical field [0001] The invention relates to the technical field of aerospace equipment, in particular to a rocket engine bracket. Background technique [0002] The rocket engine is a jet engine that uses the aircraft's own propellant (energy) and does not use the outside air. It can work in the space outside the dense atmosphere. The energy is converted into the kinetic energy of the working medium (working medium) in the rocket engine, forming a high-speed jet to discharge and generate thrust, thereby increasing the power for the rocket's movement, and the rocket engine is generally installed on the engine bracket. . [0003] In the design of the existing internal structure of the rocket, the thrust of the engine, the inertial force, and the aerodynamic load acting on the engine connection mechanism during the launch of the rocket are considered. These forces will be transmitted to the rocket body, which will easily cause serious deformation of the rocket body, which ...

Problems solved by technology

Usually, the metal plates are fixed by welding. Welding increases the weight of the bracket to a certain extent. For the rocket body, even a slight increase in weight will affect the operation of the rocket.

Moreover, during the rocket lift-off process, the welding part will be easily broken by the huge centrifugal force between the connecting parts of the bracket.
