Embodiment Construction

[0017] The invention will be described in more detail hereinafter with reference to the accompanying drawings showing embodiments of the invention. However, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In these drawings, the size and relative sizes of layers and regions may be exaggerated for clarity.

[0018] The variable-thickness casing of the solid rocket motor includes a spinning cylinder 1, a front section 2 and a rear section 3. The front section 2 and the rear section 3 are welded to the front and rear ends of the spinning cylinder 1 and adopt a structure of variable thickness. According to the overall According to the coordination requirements of the mechanical interface, according to the axial distribution positi...

Abstract

The invention discloses a variable thickness housing of a solid rocket engine, which comprises a spinning cylinder body, a front section and a rear section, wherein the spinning cylinder body is in a variable thickness structure; the front section and the rear section are welded at the front end and the rear end of the spinning cylinder body; missile wing support lugs are welded on the spinning cylinder body; and integral reinforcement with 0.5mm wall thickness is arranged on welding surfaces of the missile wing support lugs. The variable thickness housing of the solid rocket engine ensures the structural strength of the engine during working; the reliability of the engine is improved via partial thickening sections; the integral reinforcement is performed on welding parts of the missile wing support lugs via the thickening sections; external bearing requirements of missile wings on the missile wing support lugs are ensured; the passive mass is reduced; a utilization rate of a raw material is increased; and a mass ratio of the engine is increased.

Description

[0001] technical field [0002] The invention relates to the field of solid rocket motors, in particular to a variable-thickness shell of the solid rocket motor. [0003] Background technique [0004] The combustion chamber casing is one of the important parts in the engine structure. It is a storage tank filled with solid propellant and a place where the propellant burns. At the same time, it is also a component of the missile body. Under the premise of satisfying the requirements of the engine development mission statement, in the design of the engine combustion chamber shell, the various load requirements during the flight test should be considered in the structural design, and the reliable connection of the front and rear compartments should be ensured to improve the reliability of the overall structure of the missile. sex. [0005] The spinning cylinder body of the existing combustion chamber shell mainly adopts the structural form of equal thickness. [0006] The...
