US startup's bladeless VTOL can reach up to 0.8 Mach

​

According to the firm, its proprietary Fluidic Propulsion System (FPS) enables the airplane to take off and land vertically yet accelerate to jet speeds in forward flight configuration- a High-Speed VTOL (HSVTOL). "The technology presents several fundamental advantages over VTOL legacy systems, emitting lower, atonal noise and benign exhaust temperatures while eliminating rotors or propellers," said a press release.

Oh boy, it "takes advantage of Fluid Dynamics". Too bad jet engines and piston engines don't use fluid dynamics - oh, wait!

Note, the image is an RC plane. I can't see anything that explains the power system other than "compressor".

 

Yes. The freaking thing is explained only on the surface. And after looking at some "official" videos from the company, it seems that they're still keeping some secrecy as to their technology.

The only couple of videos I could find that more or less explain the tech's working principle are these:

They've made some pretty bold statements regarding their tech's efficiency. I truly hope it doesn't end up in the rather large historical bin of "Good Ideas That Couldn't Match Reality"

 

I don’t know who they think they are fooling, they are obviously pushing it with that giant fan in the background!

​

Which reminds me… (at risk of being accused of off-topic posting…)

 

I think the secret might already be out there.

Yes, that's what it is. But I'm sure they've added something else. Check this video, they've blurred out quite a few of the components:

 

If the thing is powerful enough to take-off Vertically,
then why do they have it mounted on a "Glider" ??????

If it supposedly can go "Mach-8", ( around 600-mph ),
the Glider is a really poor choice for an Airframe,
since it would completely self-destruct somewhere around ~80 to ~150-mph.

My guess is that design (of many) is targeted to the military requirements for their current contract to have a low noise glide capability.

Jetoptera wins US Army Phase II SBIR subcontract for FPS system

Under Phase I of the programme, Jetoptera’s FPS was demonstrated to have a lower overall sound pressure level (OASPL) output of almost 15 dBA.

The use of advanced acoustic measurement methods increased it to over 25dBA OASPL.

Freedom Flight Works CEO Austin Blue said: “We believe that the FPS technology developed by the team at Jetoptera opens up new and profound possibilities for signature reduction, reliability, safety, and efficiency in aviation propulsion.

The OP article seems to combine several air-frame capabilities into one for marketing simplicity.
Don't judge a fish by how well it can climb.
