Measuring and monitoring system and method suitable for high-dynamic uncontrolled detached body of aircraft

Abstract

The invention discloses a measuring and monitoring system and method suitable for a high-dynamic uncontrolled detached body of an aircraft. The system comprises a power supply module, an MEMS inertialmeasurement module, a satellite navigation receiving module, a control module, a radio frequency emission module, an image measurement module, a data storage module, a digital quantity input output module and a switching quantity input output module. According to the system and the method, the position, the speed and the posture information of the detached body can be calculated in real time in the high-dynamic uncontrolled return process of the aircraft and can be transmitted to a ground handheld terminal in real time through a wireless link, so that falling track and falling point positioninformation are provided for the recovery of the detached body.

Description

technical field [0001] The invention belongs to navigation guidance and control, and relates to a measurement and control system and method suitable for high dynamic uncontrolled return of aircraft separation bodies. Background technique [0002] All major aerospace countries and private aerospace companies in the world are actively developing the development and flight verification of reusable launch vehicles. With breakthroughs in key technologies such as rocket recovery structure, power, and control, development and flight risks and economic costs have been greatly reduced. The recovery and reuse of launch vehicles can not only greatly reduce launch costs, but also effectively control the flight debris to avoid loss of life and property. The separation body of the traditional launch vehicle falls to the ground uncontrollably after the work is finished, and the wreckage weighing several tons falls from the air to the ground, which has great destructive power. It is urgent...

AI Technical Summary

Problems solved by technology

At present, the booster generally adopts an uncontrolled reentry return method. Due to the influence of various random disturbances, the drop points of the booster are scattered widely.

When the landing area is located on land, the large area of ​​the landing area will bring about the evacuation of personnel and property and safety issues. At the same time, the remaining toxic propellant in the booster tank will pollute the environment and cause harm to personnel.
