ADVANCED ROTORCRAFT V/STOL - ROTARY WING WITH AIRPLANE QUALITIES

This paper reports on Boeing’s effort in the NASA-contracted study of “Technology Needs for High-Speed Rotorcraft.” Initially, some 15 to 20 concepts were defined for a comparative evaluation. The five most attractive concepts were selected for mission analysis and more detailed conceptual definition. This provided the data for assessment and recommendation of two concepts for the technical evaluation, advanced technology assessment, and development of an enabling technology plan.
