A Space Launch Rocket Landing Point Prediction System

Abstract

The invention discloses a landing point prediction system for space launch rockets. The technical method is connected to the aerospace measurement and control network through the landing point prediction system, and extracts the rocket wreckage and rocket flight position and speed information according to the data provided by the radar data processing system. According to the information provided by the telemetry data processing system, the separation time of the rocket wreckage is extracted, the preliminary separation point data is obtained through fitting simulation, and the flight dynamics model of the rocket wreckage is established by combining the mathematical modeling of the flight environment and the analysis of aerodynamic characteristics. Analysis of influencing factors, accurate prediction of landing point, narrowing the search range of landing area, and improving the efficiency of rocket wreckage recovery.

Description

technical field [0001] The invention relates to a system for predicting the landing point of a space launch rocket. Background technique [0002] The maximum speed of existing single-stage rockets generally does not exceed 7km / s, and it is impossible to send the carried load into the predetermined orbit. Therefore, at present, my country's aerospace test missions generally use multi-stage rockets. Each stage of a multi-stage rocket is a complete propulsion unit with its control equipment, having its own engine, propellant, tank and propellant delivery system. During the flight, the stages of the multi-stage rocket start and shut down the engines according to the program instructions, and then throw them away one by one, so as to reduce their own mass and obtain higher flight speeds. For the convenience of connection and separation, interstage sections are generally provided between the stages of multi-stage rockets, and couplings such as explosive bolts and explosive positi...
