Nice!

Hi,


here is a MD advanced hypersonic fighter concept;

Nice find! It's high time we had something new in this thread.

Hi,

I think I saw that on Scott's page as a General Dynamics project.

Very nice images hesham,thanks for sharing.

I can only what aerospace goodies are left undiscovered that Prof C didn't talk about. That man and his knowledge were a national treasure.

Good Day All -

There's no one specific X-24C thread that I can find and of the threads that mention the X-24C, this seems the best fit for these McDonnell Douglas images. The three photos are from a collection donated to the Museum by a retired McAir Engineer. Not sure of this was tunnel tested as part of McAir's own hypersonic projects or done as a contract. Note the dates on the 2nd and 3rd images.

Enjoy the Day! Mark

 

[hesham]

Great find my dear Mark.

Dear Hesham,

the illustration #3 is a mine one.
You can spot that the publisher has already respected the copyright (even with my name tranlsated in Russian!.

One can't help but wonder, with all this hypersonic work by McD, did they ever fly anything, will we ever hear about it, and is Boeing doing anything with it?

 

[XP67_Moonbat]

Prof C took those secrets to the grave. :-/

Well he didn't do everything all by himself in his Batcave.

Good Day All -

A nice find in the Parks Air College archives was this photo of Paul Czysz with a familiar model in hand. McDonnell Douglas photo dated February 1982.

Enjoy the Day! Mark

 

[Dynoman]

Awesome picture!! Hopefully there's more on Cysyz and the 192 (among others) still to be found!

Oops,sorry my dear Archipeppe,

I just seen your respond,and forgive me,I did't note your name.

 

[XP67_Moonbat]

Great find!

Great find thanks for posting

Excellent find. "Fatness ratio." I love it.

More HYFAC: Phase I trade study:

https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19710072317.pdf

Of interest to me was the discussion (PDF pages 58-73) about the propulsion options, including:

• Rubberized LR-129 up to 1 million lbf
• Aerojet concentric-nozzle hypergolic engine of up to 600K lbf
• Two different GE wraparound turboramjets
• A Marquardt variable-geometry hydrogen scramjet

Also of note is a reference to a series of “Mach 5” tests of a hydrogen-fueled scramjet in 1967-68 by United Aircraft.

The references at the end could lead to quite a few adventures in FOIAing.

You find interesting designs while looking for other information. I was thinking of writing a book on the AMI program, but the book I'm working on now is taking so long, due to difficulty getting information, I don't see an AMI book happening, so there is no reason to hang on to these. I'm not sure they belong here, but it seems the other MAC AMI design studies are here so here are two more from THIS PDF At DTIC (A004214).

Mission A (The top image) is a duct burning Mach 3+ Interceptor and Mission B (The lower image) is an air-turbo-ramjet Mach 4+ interceptor.

 

[hesham]

Wow,nice find my dear Sundog.

Captures from Discovery Channel's The Real Flying Saucers documentary

Anyone know the date of this release?

Anyone know the date of this release?

2004 sometime. Found a LinkedIn for the researcher who lists it as a freelance job from January -April 2004, so it aired some time after that.

Interesting historical note: The P&W competitor to the GE4 (SST engine) was a 57,000lb thrust duct burner.

I don't think this is it, or at least a different edit. Dr Czysz doesn't make an appearance as far as I can tell (unless it's very brief and I've skipped it)

 

[flateric]

May be a different edit. I've recorded my from Discovery Channel Russia in 2007.
I still should have dvd-r somewhere, the question is where snd if it's labeled or still playable.
The other version is I could wrong attribute screengrabs.

I think would deserve to rest at 'Postwar Secret Projects' as they are not Aurora fantasies but actual concepts

They we're tech demo's not full on strike RECCE most would fly hypersonic for only a few minutes. Notice how large the inlets are sized compared to the rest of the vehicle. These vehicles had short range allowing just enough time to gather data on propulsion, TPS etc... MCD had a very well thought-out step-by-step progression for hypersonic development. Their lifting body/TOSS back booster MOL service plan was the most comprehensive TSTO VTOHL scheme I've ever seen. Based on high flight rate RLV’s it would be the prefect blueprint for a modern private enterprise LEO RLV CATS program. I would post pics however it is not mine to distribute publicly. Perhaps that information is out there buried in some old Air force DOD reports.

Low Earth Orbit Reusable Launch Vehicle, what's CATS?

From a Paul Czysz paper in: "Scramjet Propulsion" (Cuirran and Murthy editors), Paul
discusses the McDD concept shown in the second picture:
"The resulting aircraft rather resembled the Canadian CF-106 Arrow (CF-105 actually) with very large inlets
and did not offer a significant research value with regard to fully integrated propulsion systems."

and then a little later - a very interesting observation - and RASCAL
was going in this direction, somewhat. Quoting Mr. Czysz again:

"All the afterburning turbojet/fans used in the HyFac study were conventional installations
where the airflow to the compressor increased in temperature and pressure. At about Mach
number 1.8, most compressors reach the point where the corrected speed for design efficiency
equals the machanical rotational speed limit of the compressor. At Mach numbers above this
point the mechanical speed is constant and the corrected compressor speed (N/sqrt(T/288K)
decreases. If there is a cryogenic heat exchange in the inlet between the inlet exit and
compressor entrance, then the temperature of the air entering the compressor can be kept at
that for best corrected speed, up to the Mach number limit where the heat exchanger can no
longer keep the temperature within limits. When such a turbojet is thermally integrated with a
rocket, there is no longer a transonic acceleration deficiency. This is not a classic definition of
a turbojet." I may also add, this is similar to what skylon is doing.

Were any these your possible RASCAL refs:

http://www.responsivespace.com/Papers/RS2%5CSESSION%20PAPERS%5CSESSION%208%5CLOPATA%5C8004P.pdf

http://smartech.gatech.edu/bitstream/1853/8372/1/AIAA-2005-3241.pdf

There's also the option of dumping LOX or other substances that will greatly decrease the temperature and will also increase the available oxygen content in the air to be compressed. Nitrous Oxide, N2O, is an option. Liquid is at -125degF/-90degC and it breaks into 2N2 and O2 at about 570degF/300degC. I think that's the MIPCC(?) turbofan concept.

SHAZAM again!

It's an American MiG-31!
