...as I suspect there were 2 or 3
B-52's they would have needed and they were probably heavily modded.
So just a back of the envelope says ISINGLASS was probably not fully
fuelled so that it stayed under the 53,000 lb pylon max weight.
They probably stripped the B-52 of it's normal bomber role...
...variant is different than the JP fuel and hydrogen peroxide oxidizer of the SERJ, which uses an ejector ramjet. The CIA/NRO documents on Isinglass recommend hydrogen florine for better Isp, but suggests LH2 and LOX to cut costs in half for the propulsion selection. Which is the type of system...
...me too.
CONFUSION ITEM No. 2:
Why did Bill Rose in SP: Military Space Technology, portray the Incremental Growth Vehicle (IGV) as Project ISINGLASS? It's the IGV. We've discussed it here on this forum before. Scott even posted the AWST article detailing it the other day.
Why is Bill Rose...
...of interesting stuff on Copper Canyon, and how it turned into NASP. Also DARPA's Cooper & Tony Dupont - eeeeerhmmm.
There are hints of the ISINGLASS / RHEINBERRY turf war of 1963-66 between GD-Convair and McDonnell.
Awesome stuff. Feeling excited like a kid on Christmas morning.
Is there a...
AAAH - I see where this is going. ISINGLASS / RHEINBERRY obviously had a XLR-129 (SSME ancestor) stuck into its tail. So no room for a turbojet own exhaust.
Except if it is a Harrier-like engine, with the rearward, swivelling nozzles... on the sides.
Wow. So you think they picked a BS-100 just...
Don't forget the B-52 uses fuel weight to account for both asymmetrical loading of the carried vehicle as well as keeping the CG within stability limits.
Hey guys,
Sorry to go off on a tangent but has there been a thread about Isinglass on here before? Another minor mystery for me right there with the fates of the XF-90. Again, nothing I could really find online besides a mention here or there. But that's it. Maybe somebody could post a link...
The image is not of an HGV model, but of Isinglass. Isinglass was not a GD project.
In the late 70s and early 80s DARPA pursued a program to demonstrate an air launched ballistic missile with hypersonic glider for air-to-air. This was the Ballistic Intercept Missile. The reentry vehicle was to...
I nearly made the comment that my post was relevant to yours but not particularly to the actual thread topic
edit: having said that it does tie in timewise with the General Dynamics ISINGLASS contracts of '64 - '65
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.
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...
