A distributed propulsion engine designed by US Air Force Academy cadets won a DOD research competition for the most innovative project to address warfighter challenges. The competition, sponsored by the Defense Advanced Research Projects Agency, asked teams from the mechanical and aeronautical engineering departments of the US Naval Academy, the US Military Academy, and USAFA, to design something innovative that considered impact to the warfighter. Given only those guidelines as judging criteria, 10 Academy teams began working on “projects ranging from developing unmanned aerial systems to serve as wingmen for the F-22 Raptors, to miniaturized swarms of unmanned aerial vehicle systems that perform reconnaissance and intelligence missions,” states a May 3 Academy release. The top three from a local competition were sent to compete in the DARPA Challenge this week. The winning project was developed by assistant professor of aeronautics Lt. Col. A.J. Rolling and his cadet team, whose patent-pending distributed propulsion engine saved at least 50 percent of fuel costs in lab trials by using “bleed” air to increase fuel efficiency. DARPA awarded over $200,000 to the USAFA for teams to be able to compete in the pilot project.
The long-standing method for communicating data down from space via radio frequencies has the potential to create deadly data bottlenecks that could slow and stymie future operations, according to a new report from AFA’s Mitchell Institute for Aerospace Studies. The report makes the case for combining RF with optical communications…
