Double Computers Simulation Technology for Carrier Rocket Flight Control System

The development of the carrier rocket flight control system are setting much higher requirements, it needs a new method of simulation technology to validate the correctness on the software and hardware design of the flight control computer, and complete the hardware in loop in the laboratory and at the rocketdrome. This paper just studies the technology and method and puts forward the project of double computers simulation: the form of double computers simulation system, the requirements of the software and hardware design of flight control computer, double computers synchronization simulation method, concomitancy simulation method etc. This technology and method have been applied in examination, and it satisfies the higher development requirement of carrier rocket flight control system, it has become an effective examination means.
