" That is why an ultra high altitude SS business jet is going to be here a long time before another SST.
Whether, small or big, it will be a sonic transport. I knew this early on, that whether it was cost effectiveness or efficiency or energy requirements, if these were graphed with size, the display would be a steep parabolic 'U' shape, where the smallest and largest were impractical and the median eould be more successful -- for certain technologies.
, but a sonic biz jet would be impossible with this idea, there would be no room to place any cargo anywhere with the system in the way, it would end up being an X-bizplane.
I made tentative numbers then, that a large transport capable of 100 seats would have an MTOW of 500,000lbs, heavier than Concorde but no where near her size or speed, and likely more expensive. IMO, not practical; but that was November 2001...
"Yeah, but the heat you want is 500K+. It'd be hard to find outlets to pump out 500K+ air, with the specific and very specialised flow patters, in numerous places around the airframe. I don't see how it'd be possible.
Which is why I noted the possiblity of using the engine exhaust, but it would have had to be at such an extent that the thrust levels did not go down, I didn't want this thing be a leaky pressure cooker.
Coming up with a fuselage design has been extremely difficult, with all the vents it will looked like it has been in a drive-by shooting. I worried about structural integraty as well. Like I said, I will try to come up with something describing my thoughts, but the overall shape will be in flux, so don't bitch about why there isn't what.
Yes fuel burn was an issue, of all the iterations available, the overall characteristic was a vehicle designed with blunt nose, low wave drag and enough thrust to go to supercruise.
The meaning of life is curiosity; we were put on this planet to explore opportunities.
