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]
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 V in V2500 denotes the five original partners, whilst 2500 symbolizes the original thrust level of 25000 lb f. FiatAvio later withdrew from the V2500 consortium. [2] Workshare on the joint venture's first engine, the V2500, was divided between the constituent aero-engine companies.
This was achieved through higher thrust engines (V2533-A5 or CFM56-5B3), minor structural strengthening, and an increase in fuel capacity with the installation of one or two optional 2,990 L (790 US gal) tanks in the rear underfloor hold. [15] The additional fuel tanks increased the total capacity to 30,030 L (7,930 US gal).
Lauda Air Flight 004 (NG004/LDA004) was a regularly scheduled international passenger flight from Hong Kong, via Bangkok, Thailand, to Vienna, Austria.On 26 May 1991, the Boeing 767-300ER operating the route crashed following an uncommanded deployment of the thrust reverser on the No. 1 engine during the climb phase, causing the aircraft to enter an aerodynamic stall, uncontrolled dive, and in ...
