After the cancellation of the ISINGLASS vehicle concept in 1967, the CIA was still concerned about having a Quick Reaction reconnaissance capability and pursued concept formulation for a follow-on design to the ISINGLASS concept. This concept was known as the Advanced Aircraft Reconnaissance...

I'm sorry, I'm not quite sure what you are inferring - the Isinglass study was cancelled roughly 20 years previous to the Czysz/McDonnell conversation. Could you be a bit more specific?

Not at all. There is real evidence on ISINGLASS to be uncovered, as you can see by starting at the beginning of this thread, and I'll be publishing an article on it soon. We still don't have any illustrations of what it looked like, but they certainly exist and will be released. But consider...

The X-15A2 numbers I was looking at were not (apparently) including the drop tanks - my dead tree X-15 manual is in storage. I have a question out to someone about what the max the pylon on the NB-52 could do. I suspect it's about 60,000 pounds, and this depends on the specialized pylon as well...

X-51 might be pushing it altitude-wise but it's fairly light compaed to mony of the items the B-52 has carried on it's pylons. (It'd be facinatiing to see a comprehensive list of all things ever carried on a B-52 pylon.)

Well honestly I'd say AAV, ISINGLASS and INCAAPS in terms of looks and roles, considering the X-24C wasn't produced either. But another good addition to the list nonetheless.

It's happened with a few of the links provided on this website in the past, a publication discussing Project: Isinglass was a notable one.

Mini-Isinglass, adapted to the capacity of the smaller H-6 launch platform? 35min is 2100s, no way that is referring to rocket burn time - even upper-stage engines with multiple relights reach only about 1/3 of that duration. The nose cone Paul mentions is probably what antigravite posted here...

...I suspect that after loosing Super Hustler and FISH, and later Kingfisher to Lockheeds A-12, that they were attempting to stay in the manned reconnaissnace game with the ISINGLASS. My theory is that they proposed something that looks like the VL-3A, which can be found elsewhere on Secret...

McDD has used active water cooling in a number of their designs (GRM-29, possibly ISINGLASS) http://yarchive.net/space/launchers/water_cooled_reentry.html So it may be part of that.

rocket equation applied to ISINGLASS 9.81*450*ln(132770/24450)=7469 m/s not included: air launch from the b52 +900 m/s so 8369 m/s - so close from earth orbit (9400 m/s) but not quite! maybe they should reconsider fluorine: raising isp to 500 seconds would bridge the gap. Space shuttle...

I know I'm a bit late, but do you (or anyone) have anything more on this late 1970s vehicle? It sounds like Isinglass revisited some ten years later?

...I couldn't find anything actually ISINGLASS-related like in Dyno's post. But here's brief #4. It's got some stuff from one of Professor C's earlier presentations tossed in. http://research.nianet.org/~grossman/Fundamentals/Hypersonic%20Systems%20Integration/4-HEI%20SysIntegration.pdf

Quellish, I agree. My post is based on the CIA/NRO planning document that states that FY69 there was to be three test ISINGLASS aircraft with seven rocket engines and the initiation of production of eight operational aircraft for deployment in FY71 with sixteen rocket engines. If you assume...

...that even with efforts to get things declassified there are long delays: one 1960s-era hypersonic vehicle program (apparently manned) was ISINGLASS. Decently intact declassified information on this program appeared in 2010 (although there was some release in 2006 also). But rest assured...

...for a drop from a B-52, I hear ya! For this idea to work I'm expecting that the pylon latches never see more than 53,000 lbs even after the ISINGLASS is fully fuelled. In other words, the pylon is designed so that the ISINGLASS is flying on the pylon and generating enough lift for 60% of its...

...designs had air-started SSMEs because the booster assumed takeoff alone - the SSME (indirect) ancestor was the XLR-129: RHEINBERRY / ISINGLASS engine tested at components level circa 1969. As ISINGLASS was to be dropped X-15 style, from a B-52 wing pylon, XLR-129 was air-startable. End...

The interview is covered in that thread.

Weren't the 122, 176 & 192 all McDonnell? Remember that the unmanned boost glide vehicle related to ISINGLASS was the (Y variant?) Model 122, which spanned from 1957 through to mid-sixties (and a little beyond?) edit: late-sixties, including the Alpha-Draco (B) & BGRV (E). Model No. 192 was...

Even ISINGLASS seems to have fallen down in part on IR vulnerability analysis. It's a recurring theme; you can find papers from the 80's on IR tracking of transatmospheric vehicles. Detecting and tracking the much more modest SR-72 via a small sat constellation equipped with some basic MWIR...
