The Air Force Research Lab awarded General Electric Aviation and Pratt & Whitney large-sum contracts to mature their respective next-generation military propulsion designs under the Adaptive Engine Technology Development program. These transactions appeared in the Pentagon’s list of major contracts for Oct. 19. GE Aviation received a $349.7 million task order for work through September 2016, according to the contract listing. This task order falls under the indefinite-delivery/indefinite-quantity contract mechanism that AFRL announced with the company in September. AFRL issued Pratt & Whitney a $335 million task order for its adaptive engine work through mid October 2016, states the listing. Under AETD, the Air Force is sponsoring the development of variable-cycle engines that can operate efficiently over a range of operating scenarios—such as during a fast cruise or while loitering at slower speeds—and are not limited, like conventional powerplants, to running optimally in just one scenario.
