The Airbus A321 is a member of the Airbus A320 family of short to medium range, narrow-body, commercial passenger twin engine jet airliners; [b] it carries 185 to 236 passengers. It has a stretched fuselage which was the first derivative of the baseline A320 and entered service in 1994, about six years after the original A320.
The A321neo is the second generation of Airbus's A321 family, with the first generation being the previously mentioned A321ceo. The timeline from development to first flight took 6 years, relatively short due to its nature as an improvement, as opposed to a clean-sheet designed aircraft.
Flex temp is a technique used to produce cost savings through increased engine life and reduced overhaul and fuel costs [1] for airliners by allowing them to take-off at less than rated thrust.
The A321-100 maximum takeoff weight is increased by 9,600 kg (21,200 lb) to 83,000 kg (183,000 lb). [9] To maintain performance, double-slotted flaps were included, in addition to increasing the wing area by 4 m 2 (43 sq ft), to 128 m 2 (1,380 sq ft). [27] The maiden flight of the first of two prototypes came on 11 March 1993. [14]
By increasing efficiency, a lower cruise-speed augments the range and reduces the environmental impact of aviation.According to a research project completed in 2024 and focusing on short to medium range passenger aircraft, design for subsonic instead of transonic speed (about 15% less speed) with turboprop instead of turbofan propulsion would save 21% of fuel compared to an aircraft of ...
Thrust-specific fuel consumption (TSFC) is the fuel efficiency of an engine design with respect to thrust output. TSFC may also be thought of as fuel consumption (grams/second) per unit of thrust (newtons, or N), hence thrust-specific.
TAS can be calculated as a function of Mach number and static air temperature: =, where is the speed of sound at standard sea level (661.47 knots (1,225.04 km/h; 340.29 m/s)),
The IAE V2500 is a two-shaft high-bypass turbofan engine built by International Aero Engines (IAE) which powers the Airbus A320 family, the McDonnell Douglas MD-90, and the Embraer C-390 Millennium.
