Title
Lunar Landing Research Vehicle in Flight
Full Description
In this 1965 NASA Flight Research Center photograph the Lunar Landing
Research Vehicle (LLRV) is shown at near maximum altitude over the
south base at Edwards Air Force Base.
Built of tubular aluminum like a giant four-legged bedstead, the
vehicle was to simulate a lunar landing profile from around 1500 feet
to the moon's surface. To do this, the LLRV had a General Electric CF-
700-2V turbofan engine mounted vertically in gimbals, with 4200 pounds
of thrust. The engine, using JP-4 fuel, got the vehicle up to the test
altitude and was then throttled back to support five-sixths of the
vehicle's weight, simulating the reduced gravity of the moon. Two
hydrogen-peroxide lift rockets with thrust that could be varied from
100 to 500 pounds handled the LLRV's rate of descent and horizontal
translations.
Sixteen smaller hydrogen-peroxide rockets, mounted in pairs, gave the
pilot control in pitch, yaw, and roll. On the LLRV, in case of jet
engine failure, six 500-pounds-of thrust rockets could be used by the
pilot to carefully apply lift thrust during the rapid descent to
hopefully achieve a controllable landing. The pilot's platform extended
forward between two legs while an electronics platform, similarly
located, extended rearward. The pilot had a zero-zero ejection seat
that would lift him away to safety. Weight and balance design
constraints were among the most challenging to meet for all phases of
the program (design, development, operations).
