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 B-52's US$72,000 cost per hour of flight is more than the B-1B's US$63,000 cost per hour, but less than the B-2's US$135,000 per hour. [ 232 ] The Long Range Strike Bomber program is intended to yield a stealthy successor for the B-52 and B-1 that would begin service in the 2020s; it is intended to produce 80 to 100 aircraft.
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.
B-52 54-2666. The B-52C used on the mission of Thursday January 7, 1971, with the call sign "Hiram 16", had been built in the summer of 1956 as one of thirty-five B-52C bombers. From 1952 to 1962 a total of 744 B-52s of all models were built. By January 1971, all thirty-one remaining B-52Cs were stationed at Westover Air Force Base near ...
Portions of M2-F2 footage including Peterson's spectacular crash landing were used for the 1973 television series The Six Million Dollar Man [2] though some shots during the opening credits of the series showed the later HL-10 model, during release from its carrier plane, a modified B-52. Four pilots flew the M2-F2 on its 16 glide flights.
Four B-52H Stratofortress bombers from the 69th Bomb Squadron were flown to Nellis Air Force Base to participate in exercise Red Flag 15-3, which took place 13–31 July 2015. [9] B-52 crashed on a heavyweight takeoff after aborting at high speed due to all right side engines failing after a perceived bird strike. All crew members survived.
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.
It observed that the main attachment point for the main landing gear was the rear spar of the aircraft's wing; because this spar also formed the rear wall of the main fuel tanks, the crash landing caused the tanks to rupture. The report recommended that Boeing redesign the landing gear attachment to reduce the likelihood of fuel loss in similar ...
