(By Balaseshan) United Technologies Corp. (NYSE:UTX) said its unit Pratt & Whitney has been selected for funding by the Air Force Research Laboratory (AFRL) for the Adaptive Engine Technology Development (AETD) program.
Pratt & Whitney said the AETD program is an initiative by the AFRL Propulsion Directorate to mature critical fuel-burn reduction technologies and engine design features that could transition into legacy and next generation military fighter aircraft.
The AETD program will lead to demonstration testing of an advanced high operating pressure ratio (OPR) core in late 2015, to be followed in 2016 by full engine testing of a three-stream adaptive fan and three-stream compatible augmentor and exhaust system.

The introduction of the third flow path stream will allow the engine operating conditions and resultant bypass ratio to be modulated to optimize performance across all power settings and flight conditions. This will significantly reduce total mission-weighted fuel burn.
The company said it aims to lower fuel burn up to 25% more than the current generation of fighter engines, by merging innovative adaptive engine and next generation technologies with the best features of our proven F119 and F135 engines.
"We're confident that our technical approach will ultimately give future combat aircraft added range and payload capabilities, while reducing the cost burden of expensive jet fuel. From an operational perspective, our end goal is to provide pilots more flexibility in accomplishing the mission," said Bennett Croswell, president, Pratt & Whitney Military Engines.
