For example, Concorde cruised at 1354 mph, or 7.15 million feet per hour, with its engines giving an SFC of 1.195 lb/(lbf·h) (see below); this means the engines transferred 5.98 million foot pounds per pound of fuel (17.9 MJ/kg), equivalent to an SFC of 0.50 lb/(lbf·h) for a subsonic aircraft flying at 570 mph, which would be better than even ...
The Boeing 737 Next Generation, commonly abbreviated as 737NG, or 737 Next Gen, is a twin-engine narrow-body aircraft produced by Boeing Commercial Airplanes. Launched in 1993 as the third generation derivative of the Boeing 737, it has been produced since 1997. [4] The 737NG is an upgrade of the 737 Classic (–300/–400/–500) series.
The natural outcome of this requirement is a wing design that is thin and wide, which has a low thickness-to-chord ratio. At lower speeds, undesirable parasitic drag is largely a function of the total surface area, which suggests using a wing with minimum chord, leading to the high aspect ratios seen on light aircraft and regional airliners ...
The 737-400 was replaced by the 737-800 of the Next Generation series. The 737-400SF was a 737-400 converted to freighter, though it was not a model delivered by Boeing and hence the nickname Special Freighter (SF). Alaska Airlines was the first to convert one of their 400s from regular service to an aircraft with the ability to handle 10 ...
The grounding of the 737 Max 9 after a January 5 incident that blew a hole in the side of an Alaska Airlines plane earlier this month will cost the airline about $150 million, Alaska announced ...
Southwest is the world's largest operator of the Boeing 737, and was the launch customer of the 737-300, 737-500, and 737-700. [1] It took delivery of its 1,000th Boeing 737 in 2023. Using a single basic aircraft type allows Southwest pilots and flight attendants to crew any aircraft in the fleet without restrictions.
Specific impulse (usually abbreviated I sp) is a measure of how efficiently a reaction mass engine, such as a rocket using propellant or a jet engine using fuel, generates thrust.
The Dutch flag carrier airline KLM operates a fleet of 107 aircraft. The narrow-body fleet is composed of Boeing 737 Next Generation aircraft which will be replaced by the Airbus A320neo family aircraft in 2024. Airbus A330, Boeing 777 and Boeing 787 Dreamliner wide-body aircraft are used on
