NASA and the Army Air Mobility Research and Development Laboratory had requested contract bids for design, construction, flight-test, and delivery by mid-1976 of two rotor system research aircraft (RSRA), NASA announced. The RSRA would be used in the joint NASA-Army advanced rotor concepts program to develop technology for increased performance, safety, reliability, and strength and for reduced noise, maintenance, and vibration of rotary wing aircraft. The RSRA would be based at Langley Research Center as flying laboratories to test new rotary wing concepts for civil aviation. (NASA Release 73-49)
