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 ...
During July 1986, IAE confirmed to conduct a preliminary design study for a concept examining a high-bypass engine which used the V2500 core components. This engine, commonly referred to as the SuperFan, had a projected maximum thrust of around 28,000–32,000 lbf while having only 80% of the V2500's specific fuel consumption.
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]
In December 2009, Nexcelle became a partner on the world's first truly integrated propulsion system. The company was selected to provide a combined nacelle, thrust reverser and exhaust system for the new CFM International LEAP-1C engine selected as the sole western powerplant to launch China’s COMAC C919 jetliner.
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 PW1500G variant, designed for the Airbus A220, became the first certified engine in 2013. The program cost is estimated at $10 billion. Unlike traditional turbofan engines where a single shaft connects all components, forcing them to operate at the same speed, the PW1000G has a gearbox between the fan and the low-pressure core. This allows ...
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.
