Abstract: Disclosed is a flight simulator for missiles. The system comprises means for directing heat toward the nose cone of a missile while simultaneously imparting axial rotation to the missile. Both the heat and the axial rotation are programmed to conform to actual inflight heat and spin conditions and the cycle of simultaneous heat and rotation is programmed to conform to such inflight conditions. Means are also provided for monitoring the proper fuse function at any given time during the simulated flight and for recording the entire cycle of simulated flight. The programmer can be programmed for the full real flight time of a missile such that the time-speed relationship can be matched to that of any real or proposed flight.
