Rocket lightweight efficient full-motion air rudder and manufacturing method thereof

Abstract

The invention relates to a rocket lightweight efficient full-motion air rudder and a manufacturing method thereof. The rocket lightweight efficient full-motion air rudder comprises an air rudder bodywhich comprises a framework and a rudderpost connected with the framework, the left side of the framework is provided with a left skin, and the right side of the framework is provided with a right skin. Reinforcing parts are arranged in a foam interlayer between the left skin and the right skin. By adoption of a carbon fiber resin based composite material and arrangement of the reinforcing parts in the foam interlayer between the left skin and the right skin, bearing efficiency of a rudder surface structure is remarkably improved. By assembly of the framework, the rudderpost, reinforcing rods,the foam interlayer, the left skin and the right skin through a secondary curing process after independent forming, consumption of fastening parts for component connection is avoided, and accordinglyworkload in assembly is relieved.

Description

technical field [0001] The invention relates to an air rudder, and also relates to a manufacturing method thereof. Background technique [0002] Usually, the launch vehicle is used as a means of transportation to send the payload into space. During the flight of the rocket, the flight attitude needs to be controlled, and the control rudder is the execution structure of the control system. There are two main types of control rudders: one is the gas rudder, which is installed behind the exhaust nozzle of the engine. When the high-speed airflow ejected from the combustion chamber acts on the rudder surface, it will generate control force to change the attitude of the rocket. However, this control method will lose part of the thrust; the other is the air rudder, which is often installed outside the tail section of the arrow body. control needed. [0003] In order to bear and transmit aerodynamic loads and ensure the strength and stiffness of the rudder surface, traditional air...

AI Technical Summary

Problems solved by technology

[0003] In order to bear and transmit aerodynamic loads and ensure the strength and rigidity of the rudder surface, traditional air rudders are mostly made of metal structures, which have the disadvantages of heavy structural weight and low carrying capacity.

Due to the continuous improvement of the requirements for rocket carrying capacity, metal structures are gradually difficult to meet the design requirements
