Carrier rocket sub-stage falling area range control system

Abstract

The invention discloses a carrier rocket sub-stage falling area range control system. The carrier rocket sub-stage falling area range control system comprises a grid fin structure system, a grid fin control system, a grid fin telemetering system and a ground information receiving system. Under the condition that a control unit resolves the measurement information such as the posture, the positionand the speed, a servo mechanism is controlled to deflect the fin surface by sending an instruction, so that the posture of a sub-stage of a carrier rocket is stabilized, and the sub-stage is guided to fly to the target falling area for flying landing; and the telemetering system and the ground information receiving system are used for measuring and receiving the sub-stage reentry flight information, and the sub-stage state information is monitored in real time. According to the system, the flight control time sequence and procedures are integrated, so that the sysrem has the advantages that the modification amount of the carrier rocket is small, the loss of the carrying capacity is small, the flight safety of a main task of the carrier rocket is not affected, the sub-stage falling area range of the carrier rocket can be greatly reduced, and the sub-stage return information can be monitored in real time.

Description

technical field [0001] The invention relates to a control system for the range of the sub-stage landing area of ​​a launch vehicle. Background technique [0002] The sub-stage landing area of ​​my country's launch vehicle is generally 30 kilometers wide and 50-70 kilometers long. At present, more than 20-30 high-density space launch missions are carried out every year, and tens of thousands of people need to be evacuated each time, and the sub-stage wreckage smashes houses High-voltage lines, farmland, highways and other civil facilities pollute water sources, causing serious harm to the lives and property of people in the landing area. Frequent and large-scale evacuations have seriously disrupted the normal life and production order of the people in the landing area and seriously affected China's aerospace industry. positive image. [0003] With the development of the drop zone economy, the population density continues to increase, and the uncertainty of the distribution of ...
