Many thanks to Bill Sweetman for pointing out the existence of this project.

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!!

Was that conceived during the 1950's or 1960's, or was that conceived and developed later on? Also was the document that depicts this an old document or a recently printed document or a recently made copy that depicts an old design?

I've been scanning some McAir advanced concepts artwork from the Greater St. Louis Aviation Museum archives and some of the images match up to what Overscan posted on #36 and the referenced XLR-129 powered hypersonic. Thanks to Scott L for guiding me in the right direction and making the match up.
Enjoy the Day! Mark

Very cool! I am very interested in the aircraft in the first 2 images as one of the late Rutan RASCAL MIPPC vehicle designs was a nearly identical configuration. I've seen some of the previous posts that detail the aircraft and am very interested. Sadly, I have not re-found the images I had seen of this particular Rutan design, which was a significant divergence from the other public MPV concepts.

A few bits of McAir artwork to go along with some of the designs being discussed. The 2nd, 3rd and 4th images are similar to the USAF AMI Lockheed/McD-D design blend noted in Scott's hard drive find.
Enjoy the Day! Mark
