Abstract:

The report summarizes additional technical data for evaluation of Hot Cycle propulsion system performance and operating characteristics. The tests were performed from 30 April through 26 August 1965 and included an evaluation of the performance, structural qualities, and stability and control of the Hot Cycle rotor and propulsion system in greater depth than that practical during the initial 15-hour flight test. The 20 hours of flight testing involved expansion of flight envelope and included evaluation of aircraft and rotor system performance, flight loads, cooling, and flying qualities in various flight modes. A ground test of the tethered rotor system was performed at the conclusion of flight testing, followed by a teardown inspection of the aircraft. The teardown inspection was completed on 23 December 1965.
