Simulation test system and method for carrier rocket

Abstract

The invention discloses a simulation test system and method for a carrier rocket, the system comprises a simulation test launch control system, a rocket motion simulation system and a central computer, and the central computer is respectively connected with the simulation test launch control system and the rocket motion simulation system; the rocket motion simulation system is used for performing six-degree-of-freedom simulation on a control system of the carrier rocket to generate initial rocket motion and attitude information; the simulation test launch control system is used for sending to-be-bound parameters to the central computer so as to bind flight initialization parameters of the carrier rocket; the central computer is used for performing navigation guidance control calculation based on the bound parameters and sending a control instruction to the rocket motion simulation system; and the rocket motion simulation system is also used for performing six-degree-of-freedom simulation on the control system of the carrier rocket based on the control instruction to obtain new rocket motion and attitude information. The system can complete the automatic binding of the initialization parameters of the flight control software, and greatly simplifies the test operation process.

Description

technical field [0001] The invention relates to the technical field of rocket simulation, in particular to a simulation test system and method for launch vehicles. Background technique [0002] With the vigorous development of the satellite Internet / satellite Internet of Things industry, in order to meet the needs of rapid rocket development, it is urgent to design a highly reliable and fast-verified hardware-in-the-loop simulation system. The existing hardware-in-the-loop simulation test method of the control system needs to modify the source code of the flight control software during the test, and perform manual parameter initialization and configuration. The process is relatively cumbersome, and there is a serious risk of flight control software version out of control, which reduces the confidence of the test results. , It may even lead to invalid test results, resulting in repeated tests, increasing the complexity of the development, and also affecting the development pr...
