On another site a poster reported that the highest speed they saw by the Celera prototype was 217 knots (ground speed) at 17,000', a long way short of the claims.

I agree, it looks like another Moller.

Any news on these guys?

Surprised I’m the first (I’ve found) to post this. AvWeb is usually behind the curve to begin with:

They say the Celara 500 flight tests proved their concept, but so far as I know, they've never released the data to back that up. Until they do, it's a pig in a poke.

I give this team a lot of credit. Why divulge everything, particularly if working on own dime? Time will tell but I’m on the optimistic side.. Who will buy is another question?
Best,

They've got some activity on LinkedIn and seem to be actively recruiting and hiring engineers. A good friend has tried to dance with them but got ghosted, and then months later they asked if he was interested after leaving him hanging... I think it is private equity money funding it now and that has led to non-linear hiring and progress thus far.

Sort of reminescent of Jim Bede.

I once visited a Bede open house at the Newton, Ks airport and saw both the prop and jet Bd-5's fly.

Laminar flow isn’t the controlling issue while flying at high sonic/supersonic speeds.

It’s the drag bulge at the wing fuselage intersection (solvable by area ruling). The airplane shown in the video is going to run into the same wall every other design in the last 50 years has.

Even the Concorde couldn’t overcome the issue, so they used brute force (I.e., 4 turbojet engines) to fly supersonic.

And with afterburners to get past the drag rise bump near Mach 1.

Not buying it at all. The transonic drag issue involves sound shock waves that disrupt airflow. Nothing in this presentation discusses that as best I can tell. Look at the junction between the wings and rather fat fuselage. Transonic drag issue. Whitcomb addressed this at NACA over 50 years ago.

Best of luck to them but I'm not holding my breath.

Always hard watching new players running into, and having to figure out, technology issues that others solved long ago...
