NASA has taken a significant step forward in its pursuit of quieter supersonic flight by adding two F-15 aircraft to its flight research fleet, according to information released by the agency and detailed by Space.

What role will F-15 jets play in the future of supersonic flight?

The WB-57 is a high-altitude research aircraft operated by NASA and based in Houston. Here’s what the plane is and what it’s used for.

To an untrained eye, the aircraft engine sitting outside of a Cincinnati facility in December might have looked like standard hardware. But NASA and GE Aerospace researchers watching the unit fire up for a demonstration knew what they were looking at: a hybrid engine performing at a level that could potentially power an airliner.

To help meet that challenge, The University of Texas at Arlington has received a three-year, $750,000 grant from NASA’s MUREP program to develop a new class of impact-resistant materials designed to protect next-generation aircraft during extreme landing or collision events.

An F-15 is helping NASA to gather valuable insights into how future commercial jets could save fuel and reduce the price passengers pay for airline tickets.
