Government Pilot Evaluation of the BHTI (Bell Helicopter Textron, Inc.) 206/Ring-Fin Tail Rotor.

Abstract

The Government Pilot Evaluation of the 206/Ring-Fin Tail Rotor Helicopter (Commercial Registration Number N8560F) was conducted at the Bell Helicopter Textron, Inc. test facility at Arlington, Texas between 28 November and 7 December 1984. The test required 9 flights for a total of 6 hours, of which 4.8 hours were productive. The combination of hydrualically boosted directional controls and ring-fin assembly resulted in improved low airspeed handling qualities, particularly in left sideward flight, and approximately 50% increased directional control sensitivity in forward level flight. Testing should be conducted to determine the independent effects of hydraulically boosted directional controls, and ring-fin tail rotor assembly on an OH-58C helicopter. (Author)
