One of the most common methods in development and evaluation of aerospace systems is the hardware in the loop (HWIL) test which the part of the system that must has been developed or evaluated its performance, are in hardware and other parts of the system are in software mode put in the flight simulation loop. This test is a closed-loop and real-time simulations that for its implementation, a platform named hardware in the loop test are used. In this paper the design and implementation of HWIL tester of a tactical missile flight computer system with hybrid guidance is presented. Flight computer is an essential subsystem of missile that calculations of guidance and control are done in it. This subsystem for guidance and control algorithms Implementation, collect data from seeker and other missile sensors including free gyroscopes that measure rolling angle, potentiometer of control fins and sending the appropriate commands to actuators for correcting the path of missile. For verifying the performance of this flight computer can use open loop and close loop tests. In this paper for close loop verifying of flight computer, a HWIL tester, is designed and implemented. This tester consists of two parts: hardware and software that aims to create conditions close to reality for evaluating the performance of flight computer hardware. After design of this tester, its results are compared with results of six degree of freedom missile simulation in various scenarios that the appropriate consistency of results shows the accuracy of planning.
