Abstract

The invention discloses a landing point forecasting system for space launch rocket. According to the invention, the landing point forecasting system is connected to a spaceflight test and control network. Rocket debris and rocket flight position and speed information are extracted from data provided by a radar data processing system. Rocket debris separation time is extracted according to information provided by a remote measurement data processing system. Initial separation point data is obtained through fitting simulation. A rocket debris flight dynamics model is established through combination of flight environment mathematics modeling and aerodynamic characteristics analysis. Through landing point influence factor analysis, landing point accurate forecasting is performed, so that a landing area search range is reduced and rocket debris recycling efficiency is improved.

Description

Technical field [0001] The invention relates to a prediction system for the landing point of a space launch rocket. Background technique [0002] The maximum speed of the existing single-stage rocket generally does not exceed 7km / s, and it is impossible to send the carried load into the predetermined orbit. Therefore, the current aerospace test missions in my country generally use multi-stage rockets. Each stage of a multi-stage rocket is a complete propulsion device with its control equipment, with its own engine, propellant, storage tank and propellant delivery system. During the flight, each stage of the multi-stage rocket starts and shuts off the engines according to the program instructions, and then throws them away in turn, thereby reducing its own mass and achieving higher flight speeds. In order to facilitate the connection and separation, there are generally inter-stage sections between the stages of a multi-stage rocket, using connecting parts such as explosive bolts ...
