Air Force One at Mach 5                                      Source:  Hermeus Hypersonic Jet Flying 5 Times The Speed of Sound Atlanta, Georgia based Hermeus Corporation is developing a hypersonic Mach 5 passenger jet.  The jet will be capable of flying from New York City to London in 90 minutes.  Hermeus has established a partnership with the US Air Force and with the Presidential and Executive Airlift Directorate (PE) to develop the 20 passenger vehicle for the President of the United States and his executive staff as a hypersonic Air Force One. NASA Onboard Very recently, NASA joined with Hermeus, the USAF and PE in a concerted effort to develop the jet.  Hermeus has successfully tested a prototype engine capable of powering an aircraft to travel at five times the speed of sound.  Another US company, Exosonic of California, is simultaneously part...

 Hypersonic Vehicle Cool Down Essential For Mach 5 ++ Source:  DARPA DARPA's New MACH Program For successful hypersonic vehicle flight acceleration to Mach 5 and beyond, new hypersonic architecture, materials and designs need to be innovated.  Quite simply, there's a big challenge with hypersonic aircraft that scientists have been working on for decades.  It's how to keep them cooler in their hot, leading edges in order to withstand Mach 5 plus speeds. Hypersonic Flights Takeoff The US Defense Department's Advanced Research Projects Agency - DARPA - has declared 2019 the year of the hypersonics.  DARPA is pursuing new materials, architecture and designs for cooling the hot, leading edges of hypersonic vehicles as they accelerate to Mach 5 and beyond. The program kicks off in late January 2019.  It's a great example of US innovation leadership.  For a news blog on it, go to my journalist colleague Maryanne Kane at https://www.importantinnovat...
