DARPA’s Hypersonic Vulcan Engine Meld

It might not be a Vulcan mind-meld, but it’s pretty close. The Department of Defense’s technology brain trust, the Defense Advanced Research Projects Agency (DARPA), has given 4 contractors the go-ahead to develop the advanced Vulcan combination engine system for hypersonic flight. The 8-month first phase features awards to: Alliant TechSystems, General Electric, Rolls Royce, and United Technologies.

The Vulcan engine will integrate a traditional jet turbine engine that performs well at low speeds, with a constant volume combustion (CVC) engine that performs well at higher speeds. The combination will help the vehicles go from standing starts to Mach 4 or so, where hypersonic engines can take over. DARPA’s ultimate goal is to design, build, and fly Mach 6+ re-usable, air-breathing, turbine-based hypersonic vehicles.
