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.
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]
Mockup with compressor and turbine cutaway. After the budget of NASA on aeronautics research was severely cut at the start of 2006, Pratt & Whitney committed to spend $100 million a year on the geared turbofan (GTF) development for the next generation of single-aisle airliners, focused on the 25,000–35,000 lbf (110–160 kN) thrust range.

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.
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 ...
The engine final assembly line is located at MTU Aero Engines at their location in Hanover, Germany. LAN Airlines confirmed an order for 15 Airbus A318 aircraft, for a total of 34 engines (30 installed and 4 spares) powered by PW-6000 engines on 15 August 2005. In addition, LAN signed with Pratt and Whitney to power up to 25 option aircraft.
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 ...
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.
