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 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'.
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 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 ...
Vertical landing rocket depicted in 1951 comic Rocket Ship X. Vertical landing of spaceships was the predominant mode of rocket landing envisioned in the pre-spaceflight era. Many science fiction authors as well as depictions in popular culture showed rockets landing vertically, typically resting after landing on the space vehicle's fins. This ...

A lander is a spacecraft that descends towards, then comes to rest on the surface of an astronomical body other than Earth. [1] [page needed] In contrast to an impact probe, which makes a hard landing that damages or destroys the probe upon reaching the surface, a lander makes a soft landing after which the probe remains functional.
