The engine's name is a combination of the Roman numeral V, symbolizing the five original members of the International Aero Engines consortium, which was formed in 1983 to produce the V2500 engine. The 2500 represents the 25,000- pound-force (110 kN) produced by the original engine model, the V2500-A1.
Thrust reversal, also called reverse thrust, is the temporary diversion of an aircraft engine's thrust for it to act against the forward travel of the aircraft, providing deceleration. Thrust reverser systems are featured on many jet aircraft to help slow down just after touch-down, reducing wear on the brakes and enabling shorter landing ...
IAE also supplies the V2500-E5 to power the Embraer KC-390 military transport aircraft; this arrangement is the first military application of the engine. [18] The consortium is reportedly open to further military applications for the V2500, in addition to the commercial market. [2] The engine's direct competitor is the CFM International CFM56.
The engine's projected maximum thrust was 28,000–32,000 lbf while having only 80% of the V2500's specific fuel consumption. Prior to that study the IAE shareholders Rolls-Royce plc, Pratt & Whitney and MTU Aero Engines had examined several configuration for a high-bypass engine, including several design features like a variable fan blade ...
The reverse-thrust ratio (ratio of backward engine thrust to forward reverse thrust) can be as high as 84%. [6] However, this result is obtained with a cowl to attach air flow in a 7° angle and a large enough "target" (deflector door) installed. A reverse-thrust ratio of 55% can be reached on a simple target without the cowl. [7]
Pivoting-door thrust reversers are installed on the CFM56-5. Noise-reducing chevrons can also be seen at the engine's rear. The CFM56 is designed to support several thrust reverser systems which help slow and stop the aircraft after landing. The variants built for the Boeing 737, the CFM56-3 and the CFM56-7, use a cascade type of thrust reverser.
Powerback is used by aircraft to move backwards on the ground using the power of their engines in reverse thrust operation. [1] Civil and general aviation aircraft equipped with reverse thrust are technically or theoretically able to use powerbacks as a means of "backing up" but such operation is prohibited or strongly discouraged by aircraft manufacturers as well as airport safety regulations ...
The MD-80 series, the first derivative or the second generation of the DC-9 family, entered service in 1980.The aircraft series was originally designated as Series 80 or stylized as the Super 80, [5] which was a 14 ft 3 in (4.34 m) lengthened Series 50 with a higher maximum take-off weight (MTOW) and higher fuel capacity, as well as next-generation Pratt and Whitney JT8D-200 series engines and ...
