  2. Landing gear - Wikipedia

    en.wikipedia.org/wiki/Landing_gear

    The landing gear represents 2.5 to 5% of the maximum takeoff weight (MTOW) and 1.5 to 1.75% of the aircraft cost, but 20% of the airframe direct maintenance cost. A suitably-designed wheel can support 30 t (66,000 lb), tolerate a ground speed of 300 km/h and roll a distance of 500,000 km (310,000 mi) ; it has a 20,000 hours time between overhaul and a 60,000 hours or 20 year life time.

    The speed brake was used to keep a continuous speed, and crew initiated a pre-flare maneuver to a -1.5° glideslope at an altitude of 610 m (2,000 ft). The landing gear was deployed 10 seconds prior to touchdown, when the orbiter was at an altitude of 91 m (300 ft) and traveling 150 m/s (288 kn).

    (The probe was omitted from the number 1 leg of every landing mission, to avoid a suit-puncture hazard to the astronauts, as the probes tended to break off and protrude upwards from the surface.) Equipment for the lunar exploration was carried in the modular equipment stowage assembly (MESA), a drawer mounted on a hinged panel dropping out of ...

    en.wikipedia.org/wiki/Space_Shuttle_orbiter

    The hydraulic pressure generated was also used to control all of the orbiter's flight control surfaces (the elevons, rudder, speed brake, etc.), to deploy the landing gear of the orbiter, and to retract the umbilical hose connection doors located near the rear landing gear, which supplied the orbiter's SSMEs with liquid hydrogen and oxygen from ...

    By the end of the 1990s, Menasco Aerosystems was the free world's largest producer of aircraft landing gear, with plants in California, Texas and Canada. A few of the aircraft that gear sets were made for include the A-7, F-102, C-130, C-141, the Space Shuttle, F-16, F-16E, F-18, F-18E, YF-22, B-1, C-5A, C-5B, B-52, and tip gear for the B-36.

    The main landing gear was tested in a similar way in February 2012. The nose gear landing test was the last milestone to be completed before the free flight approach and landing tests scheduled for later in 2012. [45] In August 2012, SNC completed CCiCap Milestone 1, or the 'Program Implementation Plan Review'.

  9. SpaceShipOne - Wikipedia

    en.wikipedia.org/wiki/SpaceShipOne

    The landing gear consists of two widely separated main wheels and a nose skid. These are deployed using springs, assisted by gravity. Once deployed, they cannot be retracted inflight. The spacecraft is incapable of independent takeoff from the ground. It requires a launch aircraft to carry it to launch altitude for an air launch.
