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 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]
High-thrust engines for wide-body aircraft, worth 40–45% of the market by value, will grow from 12,700 engines to over 21,000 with 18,500 deliveries. The regional jet engines below 20,000 lb (89 kN) fleet will grow from 7,500 to 9,000 and the fleet of turboprops for airliners will increase from 9,400 to 10,200.
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.

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.
A proposed 9,000 lbf (40 kN; 4,100 kgf) thrust version with a new high-pressure turbine ceramic-matrix composite tailcone [15] GMA 3010 / AE 3010 A 10,000 lbf (44.5 kN; 4,540 kgf) thrust variant, which was to power the Yakovlev Yak-77 twin-engine business jet [16] as a derated variant of the GMA 3012 with a 44 in diameter (112 cm) fan [17]
