Problems solved by technology

However, this structure also has some disadvantages
First of all, once there is a problem with the quality of diffusion welding, the oxygen and combustion channels are not completely isolated, which will lead to catastrophic consequences of explosion
In addition, the deformation of the flow channel during the diffusion welding process, or the misalignment between the laminates, will also bring serious interference and hidden dangers to the atomization quality of the propellant

Abstract

The invention discloses a dual-component attitude control thruster injector with a micro flow channel liquid collection chamber, comprising: an oxygen circuit joint, a combustion line joint, an injector structure and a thrust chamber docking interface; wherein, The oxygen circuit nozzle, the fuel circuit nozzle and the thrust chamber docking interface are integrally connected with the injector structure; the oxygen circuit nozzle is located on the side of the upstream end face of the injector structure; The other side of the upstream end face of the injector body; the butt joint of the thrust chamber is located on the downstream end face of the injector structure; One end of the flow path of the injector is connected with the nozzle of the oxygen path, and the other end of the flow path of the oxygen path of the injector is connected with the interface of the thrust chamber; The other end of the flow path of the burner is connected with the butt joint of the thrust chamber. The present invention produces high-quality atomization that enables efficient mixing and combustion of oxidant and combustion agent within the thrust chamber.

Description

Technical field [0001] The present invention belongs to the attitude control, position retention, momentum wheel unloading technology of space aircraft, and more particularly to a two-component post-controlled thrust inductor having a tiny flowway concentration liquid chamber. Background technique [0002] The two-component post-controlled thrusters achieve the spray of oxygen and burning two-way propellant by the injection. After the pressure reduction can make the propellant after the spray of high speed, the extension of the external force is quickly realized. The atomization of the droplets, evaporated, so that the two propellants are quickly carried out to gas phase spontaneous combustion reactions. [0003] For post-controlled thrusters, it is desirable to have the characteristics of light and fast response, so that the injection is small as small as possible, the structure is simple, and the channel is small. The existing concilier thrustor consists of inner flow paths in ...
