Problems solved by technology

The swinging nozzle has high requirements on the process, and has high requirements on the heat protection of the nozzle joint, and the cost is also high; although the structure of the external gas cylinder is relatively simple, the gas cylinder itself is a negative mass, and the rocket engine works At present, there are high requirements for the safety of gas cylinders, so it is still not perfect

Abstract

The invention provides a solid attitude orbit control engine gas valve and a control method thereof. The gas valve utilizes part of the gas generated by the combustion chamber of the solid rocket engine of the aircraft, and the gas valve is controlled to be ejected from the side of the aircraft, and the gas is used to use the gas. The lateral force generated by the ejection can adjust the flying attitude of the aircraft, the structure is simple, and the negative mass of the aircraft is effectively reduced.

Description

technical field [0001] The invention belongs to the field of aircraft, and in particular relates to a gas valve of a solid attitude and orbit control engine and a control method thereof. Background technique [0002] For the attitude and orbit control of solid rockets, the more commonly used method is to give the projectile an external force off the axis to correct the trajectory and attitude of the rocket. There are two commonly used methods, one is to control the swing of the nozzle to To change the direction of the thrust, the second is to bring an external gas cylinder, and apply a lateral force to the aircraft through the reverse thrust generated by the gas cylinder to achieve the purpose of changing the flight attitude of the aircraft. The swinging nozzle has high requirements on the process, and has high requirements on the heat protection of the nozzle joint, and the cost is also high; although the structure of the external gas cylinder is relatively simple, the gas ...
