The U.S. Defense Advanced Research Projects Agency (DARPA) awarded Pratt & Whitney Rocketdyne a $2.2 million contract for the fabrication and ground test of a Solar Thermal Propulsion rocket engine. This contract extends the current High Delta-V Experiment Program (HiDVE) another six months and follows a successful critical design review last March. The Solar Thermal Propulsion engine encompasses a new technology that allows it to use less fuel by harnessing the sun’s energy. This gives the satellite greater ability to maneuver in space and conduct longer missions by extending the use of its fuel.

Fuel efficiency—and the economic and ecological benefits associated with it—continues to be the white rabbit of the global aviation industry. While engine builders look toward composites and electrification, and airframe designers toward lightweighting and aerodynamics, engineers at NASA’s Glenn Research Center recently completed testing of a novel concept: the boundary layer ingesting propulsor.
S.S. White Technologies is supplying flexible rotary shafts for the Honeywell Aerospace Air Turbine Starter on the next-gen GE Aviation GE9X high-bypass turbofan engines.
Engineers successfully completed verification and validation of new Pratt & Whitney TF33 engine components at the Arnold Engineering Development Complex in Tennessee.
Uber announced a partnership with Aurora Flight Sciences to develop electric vertical takeoff and landing (eVTOL) aircraft for its Uber Elevate Network. Aurora’s eVTOL concept is derived from its existing XV-24A LightningStrike VTOL X-Plane subscale vehicle demonstrator aircraft.
