Self-throwing-separating cowling and rocket

Abstract

The invention discloses a self-throwing-separating cowling. The self-throwing-separating cowling is connected with the head of a rocket body through a butt-joint support, and comprises a cowling shelland a cowling throwing separating system, wherein the cowling shell comprises at least two cowling sheets, and the cowling sheets are spliced and connected at least through a radial-direction connecting mechanism; the cowling throwing separating system receives a control instruction of the rocket body for movement, and comprises a separating output mechanism and an axial-direction connecting mechanism which are arranged in the cowling shell, the axial-direction connecting mechanism is used for being connected with the butt-joint support and the cowling shell, and the separating output mechanism is used for pushing the cowling shell to be separated according to the preset separation velocity and posture after connection between the radial-direction connecting mechanism and the axial-direction connecting mechanism is relieved. As the cowling throwing separating system is arranged in the cowling shell, active movement of the separating output mechanism of the cowling throwing separatingsystem is used for acting, the resistance in the hypersonic speed state and the high-temperature-environment influence are overcome, the separating speed is high, the output performance is stable andreliable, and the self-throwing-separating cowling can be used for cowling separation under the harsh environmental condition.

Description

technical field [0001] The invention relates to a fairing and a rocket, in particular to a self-throwing fairing and a rocket, and belongs to the field of rocket structures. Background technique [0002] The fairing of the rocket plays the role of reducing the air resistance of the rocket and protecting its internal spacecraft. With the development of science and technology and the increasing research on basic scientific issues of hypersonic aerodynamic characteristics in China, new requirements are also put forward for the launch vehicle. The rocket throws off the fairing at hypersonic speeds without flying out of the atmosphere, releasing its internal spacecraft. [0003] Because the rocket is flying at high speed in the atmosphere, the separation environment is very harsh. The traditional method of throwing the fairing away after the rocket breaks out of the atmosphere to release its internal spacecraft and the corresponding structure, because of this design The object o...

Problems solved by technology

[0003] Because the rocket is flying at high speed in the atmosphere, the separation environment is very harsh. The traditional method of throwing the fairing away after the rocket breaks out of the atmosphere to release its internal spacecraft and the corresponding structure, because of this design The object of use is used under relatively small resistance after rushing out of the atmosphere, and the separation driving force provided by its separation structure can no longer meet the demand in the very harsh environment of high temperature and large wind resistance.
