The U.S. aerospace sector can encourage research to benefit the emerging and competitive field of military and even commercial hypersonic flight, a panel of executives and government officials said July 10 at the 2018 AIAA Propulsion and Energy Forum in Cincinnati.

Hypersonic weapons and military aircraft have been around for 60 years, but advancing the science requires new ways of thinking, said Christopher Clay, program manager of DARPA’s Tactical Technology Office. Clay encouraged the audience to find the disrupters in their organizations.

“Avoid those people who say they are using best practices, because by definition, a best practice is an old practice,” he said.

The lion’s share of hypersonic research the U.S. Air Force is doing is directed at air-breathing and boost glide expendable vehicles, including missiles, which are “becoming close to operationalized,” said Douglas Blake, director of the Aerospace Systems Directorate at the U.S. Air Force Research Laboratory.

That research into expendable vehicles must be successful to maintain interest in hypersonic research and to develop techniques that will feed forward to more far-term technologies, including reusable planes, Blake said.

During the AIAA AVIATION Forum in June in Atlanta, Boeing unveiled a concept for a commercial airliner that would travel at Mach 5. Kevin Bowcutt, chief scientist of hypersonics at Boeing, is leading that effort.

“The foundation under which we are working is not as strong as it could be,” Bowcutt said of U.S. hypersonics research. “Hypersonic funding has been very cyclic.”

Bowcutt said people have left the field of hypersonic research because of inconsistent government funding, so he echoed the other speakers in their optimism that hypersonic flight is a priority for Michael Griffin, the Pentagon’s undersecretary of defense for research and engineering.

“The hypersonics talent pool must be enlarged,” Bowcutt said, calling for public speaking to encourage students to work with government and industry on hypersonics and for NASA to become more involved in hypersonic flight.
