Stephane, welcome onboard and thanks for wonderful stuff!
Would you mind if we will move this thread to McDonnell Douglas hypersonic thread?

BTW, Mr.Czysz is not far away=)

Anyway, since i know the Aurora drawing for the Bill Sweetman book was heavily influenced by input from Professor Czysz, no surprise there since this is also an MDD design from the same time period.
I want to find out more about the inlet system of that particular design, it does not use the front fuselage as a compression ramp, which is a bit strange for something going Mach 6. Have to check more.
If you don't use the forebody for compression, you could still put a compression surface inside the
engine module, but it makes the engine module longer as it is now not just an isolator/combustor/nozzle,
but a inlet, isolator, combustor, nozzle. If it's subsonic combustion, then no isolator. And there could be
good reasons for putting it in the module if you want to play around with different modules.
Depending on which picture you're talking about, if it is the Czysz (there are NO VOWELS IN THIS GUYS LAST NAME!!)
Mach 6 Interceptor drawing you posted (thanks for that by the way), you can see a possible compression ramp
in the front of the engine module. There may be an internal compression function as well.
This must have been a pretty exciting time at MCDD when they were designing these things!!
