TRACKING TESTS WITH SPERRY HELICOPTER FIRE CONTROL SYSTEM MOUNTED IN AN H21 HELICOPTER

Abstract

The testing of a stabilized sighting system mounted in an H21 helicopter is described. This sight is unique in that stabilization signals are generated by the navigational equipment already available in the airship. Tracking error under a wide variety of flight and target conditions averaged approximately 2 mils rms. It was concluded that while the hardware tested had certain deficiencies, particularly regarding vibration, the principle of obtaining signals from the aircraft navigational equipment for sight stabilization had promise. This is particularly true for systems where angular tracking accuracy of approximately 3 mils is acceptable. (Author)
