To minimize development risk, early evaluation of digital flight control algorithms is essential in the design of a missile flight control system. To minimize cost and time, these algorithms need not be evaluated in flight tests but can be coded on a prototype flight computer and tested in a hardware-in-the-loop, real-time simulation environment. This type of testing presents a more realistic environment than an all-software simulation. The hardware typically included in the simulation is a prototype flight computer with the digital flight control algorithms coded, an inertial measurement unit (IMU) mounted on a motion table, and fin actuator units (FAU's) connected to dynamic loading fixtures that simulate the actual flight loads. This paper discusses one such hardware-in-the-loop test which was performed to test a proposed digital flight control system. The tests proved to be useful and successful. Included in this paper are a description of the building of the hardware/software test bed, the evolutionary process of integrating the test hardware and software with the flight hardware and software, and a summary of the results of the tests.
