Gear retraction of a Velocity on takeoff. The Velocity XL is 12 in (310 mm) longer and has a 20 in (510 mm) greater span than the SE. [3] The standard XL has a cruising range of 875 nautical miles (1,620 km; 1,007 mi) and a 75% power cruising speed of 185 knots (213 mph; 343 km/h) air speed.
A Boeing 747-400's main landing gear. Note the toes-up bias angle of the bogies on the wing gear, to ensure correct stowage upon retraction: 707, 720, 757, 767, 787: 10 wheels [1x2]+[2x4] A Boeing 757-200 from British Airways: 777: 14 wheels [1x2]+[2x6] A Boeing 777-200 from United Airlines.
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.
GUMPS is an acronym widely used by retractable gear aircraft pilots as a mental checklist to ensure nothing critical has been forgotten before landing. Its popularity is widespread, appearing in flight student curricula, FAA publications and aviation magazines.
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 landing gear is also of a different design. [3] The Liberty was designed by Ivan Shaw, who also created the Europa. The aircraft has a composite fuselage and aluminum wings. The engine is a fuel injected FADEC (Full Authority Digital Engine Control) equipped Continental IOF-240–B driving an MT composite propeller. [4]
It also focuses on ancillary systems such as steering control, landing gear control and indication, emergency control, brake control, wheels, brakes, tires, door mechanisms and electrical harnesses. This site is the final assembly area where landing gear systems for many aircraft are fully assembled and tested before shipping to the customer.
