DARPA awarded Pratt & Whitney Rocketdyne a contract, with a value up to $1 million, to design an engine for the Transformer (TX), a vertical takeoff and landing, road-worthy concept study vehicle. The engine design will use technology from the EnduroCORE engine developed by P&WR. The EnduroCORE engine is a durable, lightweight, high-performance diesel engine designed to support applications ranging from propulsion to power generation. The TX vehicle, still in its conceptual phase, will be designed to carry up to four people. It will be capable of vertical takeoff and landing and traveling up to 250 nmi without having to refuel. P&WR will work with two DARPA prime contractors to develop a conceptual design of an engine for TX vehicles that could be developed and available by 2015.
