HyperStar AeroSpace Mach 5 Jet

Recommended Posts

I've never heard of this before, but it's been mentioned by 2 aerospace publications this week.

They're also listening impressive specs and technologies that I've also never heard of before.

  • Mach 5 at 80,000 feet and 7,000-nm range
  • 36 passengers
  • Electromagnetic drag reduction technology (EDRT)
    • a generated plasma ion field is pulsed around strategic fuselage, wing and tail surfaces to create active laminar flow control at the boundary layer interface.
  • H-Magjet 5500-X hybrid turbofan ramjet engines
    • superconducting turbo power core ring to generate the aircraft’s high electrical power requirements.
    • electromagnetic compressor and bypass fans.

Sounds pretty exotic.

What are your thoughts?

"Exotic" is the right word choice. Never heard of the company or the concept before... nor of the technology they want to use o.O;

But: being able to mitigate the sonic boom would be the holy grail of supersonic aircraft. So I hope this actually works.

Migrating the sonic boom should work, some NASA test planes manages this. 
Has been some other ideas for an supersonic business jet but then mach 2. 

Using electrical coupling between the turbine and compressor is interesting but superconducting is problematic.

There are shapes that reduce sonic boom, but it still remains a problem.  Another difficulty is simple economics.  Supersonic flight is expensive.  Hypersonic flight even more so.  The turnaround time for hypersonic aircraft is high too.

A lot of exotic propositions come out in aerospace as cash grabs.  Without downplaying the value of innovation, there are also a lot of con meant and con organizations that just want to abscond with the funds of venture capitalists, etc.  That said, there is a market for getting wealthy fops from a to b as fast as possible and with as much dramatic flare as possible.  It is plausible that suborbital spaceplanes will be part of corporate or royal flight departments in the future.  

Similar proposals like the Boeing Waverider, etc. exist.

I remember hearing rumors of electrohydrodynamical propulsion technologies as far back as the 90's (the rumors were associated with the aurora project if I'm remembering correctly). As I understood it at the time, the proposed system would use a powerful electromagnetic field to turn the atmosphere in front of the craft into an ionized plasma, and then use other fields to pull the plasma around and past the craft nearly eliminating drag. This sounds like a similar technology, or perhaps a better explanation of the technology. I hadn't heard of this project or this company before. Thanks for sharing!

If aerodynamics and physics worked such that we could effectively get rid of drag then we'd have no trouble getting to orbit in small SSTOs by now. 

This concept, as far as I can tell, intends to use ionised air to reduce the drag contribution of the boundary layer around the aircraft. This would give a notable reduction in drag (and probably more importntly the skin heating) but certainly would not almost eliminate it.

i heard about this drag reduction technology with reference to that oddball airship to orbit scheme thats been floating around here, the one with the kilometer long flying wing in a v shape, a scheme that seems mad enough to work. pretty straight foward, flow an ion stream (i presume negative) over the wing and other draghappy parts and get a friction free buffer between the surface and the air.

Plasma field? Superconducting electric engines? Bunk. Absolute bunk.

Or not bunk but an empty marketing exercise - note that those aren't photographs.

 

This plasma field - it is supposed to, simultaneously, reduce drag, reduce fuselage heating AND eliminate the sonic boom? No. No No No.

Could you build a Mach 5 business jet that has no sonic boom? Yeah, maybe, need some good engines, but this thing is science fiction.
