Problems solved by technology

[0004] In the prior art, the static instability is reduced by adding stabilizers, and the demand for the control capability of the vector power system is reduced. However, the stabilizers provide resistance during the flight of the rocket, which is not conducive to the flight of the rocket.
Conventional aerodynamic rudder surfaces in the prior art include cross-shaped control rudder surfaces and X-shaped control rudder surfaces (that is, cross-shaped control rudder surfaces rotate 45 degrees). The control rudder surfaces provide stability on the one hand, and serve as control rudder surfaces The flight attitude of the rocket is changed by means of deflection. During the whole flight of the rocket, the conventional aerodynamic rudder surface has resistance, and requires a relatively large servo motion system to support the rocket, which makes the rocket carry a large weight, and the rocket manufacturing cost is high.

Description

Technical field [0001] The present application relates to the field of rocket technologies, and more particularly to a rocket with embedded pneumatic control rudder surface. Background technique [0002] Currently, SolidPropellantrocketEngine uses a chemical rocket engine of a solid propellant. Also known as solid propellant rocket engines. After the solid propeller is ignited, combustion in the combustion chamber, chemically converted into thermal energy, producing high-temperature high pressure combustion products. The combustion product flows through the nozzle, and the thermal energy transition is kinetic energy, which is thrown from the nozzle discharge in high speed. [0003] In the prior art, the solid rocket engine uses the pure spingent layout of swing nozzle, no wing and the steering gear. The pressure is often at a position of about 30% from the rocket pointed point, and its static instability is large, and the control of the vector power system. Ability is extremely h...
