Pratt & Whitney, an RTX business, has completed a series of tests on its rotating detonation engine (RDE) work with the RTX Technology Research Center. Positive test results are spurring additional internal investment as Pratt & Whitney works with Department of Defense to accelerate a path to an integrated engine and vehicle ground test in the coming years.
Rotating detonation engines differ from traditional turbojet or turbofan engines in that they utilize a different thermodynamic cycle and require no moving parts. The result is high thermal efficiency and performance, which allows for a small, compact and cost-effective engine. These attributes create room for additional fuel, sensors and payload, and can enable longer-range for vehicles that are critical to future defense applications.
