An IAE V2500 fitted on a Brazilian Air Force Embraer C-390. A number of de-rated, Stage 4 noise compliant engines have been produced from the -A5 configuration, as well as two variants with significant increase in thrust, thus expanding the thrust range from 23,500 lbf to 33,000 lbf: The 23,500 lbf (105 kN) thrust V2524-A5 for the Airbus A319
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'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 ...
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]
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 aircraft landed safely. A post-landing inspection showed that one of the 585-pound, 4-foot-wide, 5-foot-long thrust reversers had fallen off the aircraft. Divers later found the thrust reverser on the bottom of the nearby Banana River. An investigation showed that a bolt failed, releasing the part from the aircraft. [3] [4]
Using a parked DC-8, investigators replicated Captain McLachlan's technique and found that at sufficient speeds, the inertia force created by the movement could cause the thrust brake lever to enter the reverse detent. The number four engine reverser lights had activated, and a physical inspection confirmed the deployment of the number four engine.
