Really hoping they win. I think the MIC desperately needs a new guy to come in and light a fire up their asses to get shit done faster and cheaper.

What's the difference between super sonic and hyper sonic? Is hyper more sonic-er-er?

The first "publicly acknowledged" hypersonic air breathing aircraft. I'm in the camp that we've had some version since the 90's, albeit in very limited numbers, probably single digits.

We were supplying some alloy Ti sheet for the fuselage, but not sure if they managed to keep the business. Hope they didn’t lose the orders because it got pretty quiet. - it was only this one plane so far, though.
It was a derivative of 6-4 more or less. Not like the beta alloy used on the SR-71 (or whatever the skunk works built in the early 1990s) |

The plane in the video is a subsonic test mule, that's good. It has a slue of raised and exposed screws/rivets. I suppose future supersonic and hypersonic versions will be smooth.

I wish them the best. Based solely on the YouTube video it sounds like they’re very focused on making a business of their endeavor. It sounds mostly plausible.
They’re not talking about X-15 speeds but greater than SR-71 speeds. That’s a lot of friction-generated heat with which to cope. Crossing my fingers they have a plan for that. |

Its a scaled test mule. They have to test their ramjet invention.
Their goal is a passenger or military aircraft that is very similar to the XB-70-using their ramjet design. I would suspect most everything has been lost from that program and they have to basically start over. If the ramjet works out, then the larger aircraft may be viable. |

ATLANTA, GA – Hermeus has accepted its first F100 engine from Pratt & Whitney. Set to be integrated into the enhanced Chimera II turbine-based combined cycle (TBCC) propulsion system, this powerful engine component marks a critical milestone in Hermeus' development of Darkhorse which is set to unlock new possibilities in both military and commercial hypersonic applications.
Recognizing propulsion as the critical challenge in achieving hypersonic flight, Hermeus has been dedicated to the development of its proprietary turbine-based combined cycle (TBCC) engine architecture without diluting their efforts in reconstructing already proven and reliable components. The F100 will propel the unmanned Darkhorse aircraft to speeds of approximately Mach 2.8. At this transition point, a ramjet will take over, propelling Darkhorse to its target velocity of Mach 5. While developing Quarterhorse, a demonstrator vehicle designed for high-Mach flight testing, the Hermeus engine architecture has been proven through the first iteration of Chimera which utilizes the General Electric J85 as its core. Consistent with their fundamentals Hermeus has developed and manufactured in-house the other engine components including the inlet, precooler, ram burner, and bypass system. These elements will all be scaled up for integration into the advanced Chimera II.
