1965.01.26 - Apollo Lunar Landing Research Vehicle results


Warren J. North, Chairman of the Lunar Landing Research Vehicle (LLRV) Coordination Panel, reported to MSC Director Robert R. Gilruth that the LLRV had been flown 10 times by Flight Research Center pilots - eight times by Joe Walker and twice by Don Mallick. Maximum altitude achieved was 91 m (300 ft) and maximum forward velocity was 12 m (40 ft) per sec.

Subsequent to December 14, 1964, the vehicle had been undergoing detailed x-ray inspection, lunar simulation control system checkout, and minor changes prior to extending the flight envelope in February.

North said discussions with the pilots indicated that checkout prerequisites for future LLRV pilots should include helicopter proficiency plus at least two weeks of intensive simulator and vehicle test stand activity. Prototypes of the basic LEM controls and displays were being procured by MSC and would be phased into the LLRV simulator and flight vehicles during the spring and summer.
