XV-5A LIFT FAN FLIGHT RESEARCH AIRCRAFT
Abstract
The lateral control investigation was completed with the static load test successfully completed at San Diego, the necessary hardware manufactured and modification to aircraft number 2 completed, with Edwards vertical thrust stand plus flight testing verification of the increased lateral control power. Full scale wind tunnel testing was completed with aircraft number 1, and the aircraft returned to Edwards for preparation for flight test. Lift fan inlet vane failures were experienced during the wind tunnel tests, modifications designed, manufactured, and tested to establish a flight envelope. Potential longitudinal trim problems were seen during the wind tunnel, a horizontal tail slat and instrumentation boom for measuring tail angle of attack were designed and installed on aircraft number 2. The nose wheel shimmy investigation was completed and modifications accomplished to the aircraft which allowed successful conventional flights to commence May 25, 1964. Initial hover flights began on July 16, 1964. A J85 stall investigation was conducted as a result of several compressor stalls experienced during flight. Two hover flights were successfully accomplished without stalls utilizing J58's in a 'stall-free' configuration.
