Stratolaunch has a twin-fuselage configuration, each 238 ft (73 m) long and supported by 12 main landing gear wheels and two nose gear wheels, for a total of 28 wheels. [18] The twin-fuselage configuration is similar to the Scaled Composites White Knight Two. [15] Each fuselage has its own empennage. [39]
Doing away with the need for "staging" with launch vehicles, such as with the Shuttle and the Apollo rockets, would lead to an inherently more reliable and safer space launch vehicle. While the X-33 would not approach airplane-like safety, the X-33 would attempt to demonstrate 0.997 reliability, or 3 mishaps out of 1,000 launches, which would ...
The carrier plane is powered by six Pratt & Whitney PW4000, 46,000–66,500 lbf (205,000–296,000 N) thrust-range jet engines, sourced from two used 747-400s that were cannibalized for engines, avionics, flight deck, landing gear and other proven systems to reduce initial development costs. The carrier is designed to have a range of 2,200 km ...
(Reuters) -Elon Musk's SpaceX launched its giant Starship rocket to space from Texas on Tuesday, advancing the ship's spaceflight abilities but botching an attempt to bring its booster back to ...
It was intended to use the technology on Dragon 2, their second generation crew-carrying reusable space capsule, for landing after returning from space, as well as a launch abort system. The DragonFly prototype was used for low-altitude propulsive flight testing in 2014 and 2015. [23] Development was abandoned by mid-2017. [24]
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.
July 26: Space Shuttle Discovery STS-114 launch. Space Shuttle Discovery rising from the pad at Kennedy Space Center, Florida, 10:39 am, July 26, 2005. STS-114 marked the return to flight of the Space Shuttle after the Columbia disaster and was the second Shuttle flight with a female commander (Eileen Collins, who also commanded the STS-93 ...
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'.
