The original cost-plus-incentive-fee contract to Boeing (with Delco as a major sub-contractor) was for $19 million and called for delivery of the first LRV by 1 April 1971, but cost overruns led to a final cost of $38 million. Bekker, now with General Motors Defense Research Laboratories (GMDRL) at Santa Barbara, California, was completing a study for NASA's In early 1963, NASA selected MSFC for studies in an Apollo Logistics Support System (ALSS). The suspension consisted of a double horizontal wishbone with upper and lower torsion bars and a damper unit between the chassis and upper wishbone. It is termed the Lunar Roving Vehicle (LRV) or Rover (figure 12). Navigation was based on continuously recording direction and distance through use of a directional gyro and odometer and inputting this data to a computer which would keep track of the overall direction and distance back to the LM. WIR BAUEN IHREN LUNAR ROVER! Scientist-astronaut The LRVs experienced some minor problems. A nave espacial Apollo apenas podia transportar uma determinada massa fixa e rodas constituídas de malhas de cordas foram utilizadas para manter baixo o peso do veículo. One astronaut would climb the egress ladder on the LM and release the rover, which would then be slowly tilted out by the second astronaut on the ground through the use of reels and tapes. With an urgent need to determine the feasibility of a two-man LSSM, von Braun bypassed the usual procurement process and had P&VE's Advanced Studies Office directly task BECO to design, build, and test a MTA for the vehicle.In designing the LSSM MTA, full use was made of all earlier small-rover studies, and commercially available components were incorporated wherever possible.
It is powered by two silver-zinc, 36-volt batteries and has an individual electric motor £or each o£ the £our wheels. The LRV carried tools, scientific equipment, communications gear, and lunar samples. Fully loaded the LRV had a ground clearance of 36 cm. Moving the stick forward powered the LRV forward, left and right turned the vehicle left or right, and pulling backwards activated the brakes. Dust guards were mounted above the wheels. The rear The fender extension on the Apollo 17 LRV broke when accidentally bumped by The wheels were designed and manufactured by General Motors Defense Research Laboratories in Santa Barbara, California.Maneuvering capability was provided through the use of front and rear steering motors. The LRV could be operated by either astronaut.The LRV was the first manned surface transportation system designed to operate on the Moon. The concept of a lunar rover predated Apollo, with a 1952–1954 series in Collier's Weekly magazine by Wernher von Braun and others, \"Man Will Conquer Space Soon!\" In this, von Braun described a six-week stay on the Moon, featuring 10-ton tractor trailers for moving supplies.In 1956, Mieczyslaw G. Bekker published two books on land locomotion. The frame was 3.1 meters long with a wheelbase of 2.3 meters. On Apollo 16 the vehicle traversed 26.7 km in 3 hours 26 minutes of driving. The concept of a lunar rover predated Apollo, with a 1952–1954 series in Beginning in the early 1960s, a series of studies centering on lunar mobility were conducted under MSFC. . Activating a switch on the handle before pulling back would put the LRV into reverse. On the MTA, each wheel had a small electric motor, with overall power provided by standard truck batteries. In early planning for the The LLS studies were begun by Grumman and Northrop in the fall of 1962; these were designs for pressurized cabin vehicles with electric motors for each wheel. The LUNAR ROVING VEHICLE: The Lunar Roving Vehicle (LRV) was an electric vehicle designed to operate in the low-gravity vacuum of the Moon and to be capable of traversing the lunar surface, allowing the Apollo astronauts to extend the range of their surface extravehicular activities. Included was the need for a pressurized vehicle in the 6,490–8,470 lb (Even as ALSS was underway, MSFC was examining a less ambitious surface exploration activity, the Local Scientific Surface Module (LSSM). It had two side-by-side foldable seats made of tubular aluminum with nylon webbing and aluminum floor panels. This began with the Lunar Logistics System (LLS), followed by the Mobility Laboratory (MOLAB), then the Lunar Scientific Survey Module (LSSM), and finally the Mobility Test Article (MTA). The LSSM performance under one-sixth gravity was obtained through flights on a KC-135A aircraft in a On 11 July 1969, just before the successful Moon landing of The first cost-plus-incentive-fee contract to Boeing was for $19,000,000 and called for delivery of the first LRV by 1 April 1971. The rover was folded and stored in the bay with the underside of the chassis facing out.
