Near space atmosphere environment detector and operating method thereof

Abstract

The invention provides a near space atmosphere environment detector and an operating method thereof. The detector comprises a load grade system and a booster grade system; the booster grade system comprises a rocket body structure, a booster grade control subsystem and a booster grade power mechanism; the booster grade control subsystem is used for detecting the attitude and motion information of the rocket body structure when the load grade system is separated, and then controls the operation of the booster grade power mechanism according to the attitude and motion information of the rocket body structure, and therefore backward-thrust braking is provided to make the rocket body structure land in the vertical direction; the load grade system comprises a payload bay carried with an environment detection instrument, a load grade control subsystem and a load grade power mechanism; the load grade control subsystem is used for controlling the load grade power mechanism to operate in dependence on detected attitude, height, motion and guidance information, control of flying trajectories of the payload bay, the load grade control subsystem and the load grade power mechanism is achieved, and at least two times of skip flying is achieved.

Description

technical field [0001] The invention relates to the detection of the atmospheric environment of the near space, in particular to a detector of the atmospheric environment of the near space and its operation method. Background technique [0002] With the development of a new generation of aircraft, aerostats and suborbital spacecraft, near space is becoming a new field for high-tech applications and national defense and security activities. The launch and testing of various spacecraft and near space vehicles require near space Provide space environment assurance (such as meteorological assurance). The environmental elements of the adjacent space mainly include the gas composition, temperature, density, pressure, wind, and disturbance of the atmosphere. It is a very important and valuable airspace, and it is also an area that is relatively poorly understood at present. Near-space environment detection with an altitude range of 40km to 100km is too high for balloons, but in-si...

AI Technical Summary

Problems solved by technology

[0004] 1. The flight environment is relatively harsh: solid rocket motors are used, and the thrust is relatively large, resulting in relatively large flight speed and overload, which will have an adverse effect on the payload during the flight, and also put forward higher technical requirements for the payload system design. ;

[0005] 2. Uncontrolled flight limits its application: Sounding rockets use uncontrolled flight, which is poor in coping with external disturbances and environmental changes, and there are hidden dangers in the safety of the wreckage landing area. A dedicated launch site, which also limits the detection area of ​​the sounding rocket to a certain area around the launch site, failing to detect the environmental parameters of the adjacent space on a large scale;

[0006] 3. The cost of one-time use is high: the existing sounding rockets are basically one-time use, and the economy is poor. At present, the low-cost trend has emerged in the aerospace field, and the gradual improvement measures use repeated use instead of one-time use to reduce costs. ;
