In order to realize the rapid, cheap and efficient design of the aircraft control system, a design scheme of the sub-orbital aircraft control system based on the rapid control prototype technology is proposed and the software and hardware design and real-time simulation of the system are completed. The system consists of overall control computer, two real-time numerical simulation machines, VMIC, hardware interface and physical equipment. The six-DOF motion model of sub-orbital aircraft reentry stage is established. The control distribution is designed and the attitude control is designed by classical control method. Distributed rapid prototyping through the Rt Fly platform. The simulation results show that the control parameters are easily adjusted and the real-time performance of the system is good. The rapid prototyping technology can be effectively applied in the design of the aircraft control system.
