For the combined cycle engine (TBCC) you can check out Lockheeds SR-72 proposal. Its their latest attempt to make it work, surprisingly its a white
world sells pitch. Tells you all about its chances.
This is a Nasa slideshow on the TBCC:
If you can make sense of it, i'm no that interested in technical details...
This CalTech study argues against the previous (?) 'aircraft at Mach 5' thesis:
I havent found much beyond that on sonic booms (other than pulse detonating donuts confirmed !!11!!) but as said, i'm sure they tried to build an
SR-71 successor. Maybe they even pushed the envelop beyond Mach 4 with some Kind of demonstrator, but fuel consumption and efficiency issues remain.
Also from a tactical viewpoint, i dont believe you do much better against modern russian SAM systems at Mach 4 instead of Mach 3. They are designed to
engage hypersonic cruise missiles and ballistic at terminal velocity. So why bother.
Mach 6 to 10 or even faster might result in a significantly reduced engagement zone but such a craft is way off IMO.
I have no specific inside on Wichita or Amarillo. Your guess is as good as mine. I'm a nobody with no access to anything interesting.
According to Zaphod Wichita is a Grey World aircraft, manned, relativley new, not the A-12, not the RQ-180 and not the NGLRS-D.
Personally i believe at least one bit of Information is (unintentionally) wrong, but who knows. I'd like it to be some sort of LO LPI AEW craft but as
said, your guess is as good as mine. Doesnt look 'fast' to me though.
Dont want to derail the thread even more... the F-35 is probably ok for a multirole aircraft. I just think way too many other procurement programs
suffered because of JSF and despite that, the US will probably end up with less F-35 than it needs. Classic too big to fail / there is no
