ABSTRACT Three-axis flying posture simulator is a set of precise and sophisticated equipment with important significance of economy and national defence. TFPS is a kind of powerful instrument used to reproduce the flying posture of flying weapons in laboratory. TFPS, together with equipment producing infrared target, simulates the attacked target and flying missile, which can really simulate the various flying postures in space and dynamic characteristics. Thus, the performances of sensors, control system and actuator and so on can be tested and evaluated, which provides various reference bases for developing, improving and redesigning flying weapons.
