When I think about it, too bad someone could not have videotaped it. ;D
http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19980231024_1998376505.pdfThis paper surveys the basic configuration options available to a Liquid Fly Back Booster (LFBB), integrated with the Space Shuttle system. The background of the development of the LFBB concept is given. The influence of the main booster engine (BME) installations and the Fly Back Engine (FBE) installation on the aerodynamic configurations are also discussed. Limits on the LFBB configuration design space imposed by the existing Shuttle flight and ground elements are also described. The objective of the paper is to put the constrains and design space for an LFBB in perspective. The object of the work is to define LFBB configurations that significantly improve safety, operability, reliability and performance of the Shuttle system and dramatically lower operations costs.

OM said:...Scott, can you tweak the contrast just a little on this one? I honestly can't make out 1/10th of what's there because it's so light.
Michel Van said:there were other crazy "Ideas" would likely rupture the ET:
like put SRB segments or a Titan-II stage under the ET as "add-on Booster"
LBM 4 Titan-II tanks with total 159t fuel and 2xAerojet LR87-AJ-11 engine with total 200 ton trust
total weight 180t LBM ignition 5 sec after Shuttle liftoff
+5 tons payload for USAF mission (from Vandenberg AFB?)
blackstar said:Michel Van said:Wat i wonder is, had Martin never proposed Transtage for Shuttle upperstage ?
(they had proposed Transtage as ad-on booster under the ET in 1982)
I think they did. There's a congressional hearing report from around 1972 or so that includes presentations from about four different companies proposing "space tugs" for the shuttle. There were several Agena proposals, a Grumman proposal, and I think a Martin proposal using the Transtage. I'll look around for it in my files. From vague memory, I think that the Transtage had some early performance problems, but these were later solved. However, I believe I also heard from some people familiar with it that it was not very popular. The Air Force people who had to work with it did not like it.
I remember that there were at least three Agena proposals--a "large tank" Agena (their preferred design), an Agena with drop tanks, and three separate Agenas with separate payloads.
Michel Van said:Agena in a shuttle bay = as dangerous as a Centaur ?
(non cryogenic, but highly toxic corrosive... on the other hand Shuttle OMS use storable propellants)
the OMS used fuel is monomethylhydrazine (MMH), which is oxidized with nitrogen tetroxide (N2O4).
Monomethylhydrazine - Wikipedia

the Agena used fuel is UDMH , which is oxidized with Inhibited white fuming nitric acid

something you don't want in a Shuttle cargobay in case the oxidizer tank, feedline or valve leaksBeing a powerful oxidizing agent, nitric acid reacts violently with many organic materials and the reactions may be explosive

Orionblamblam said:But if the Shuttle did have to put down somewhere unusual, NASA would have a hell of a time picking it up and putting it on the 747.
Triton said:Orionblamblam said:Triton said:Does anyone know if there were any real plans to deliver nuclear weapons from the Space Shuttle cargo bay?
Not really, no. Undoubtedly the USAF noodled the idea around, but orbiting nukes have never been particularly popular.
Interesting. According to Efraim Akin at the Institute of Applied Mathematics (IPM) of the Soviet Academy of Sciences:
When we analyzed the trajectories from Vandenberg we saw that it was possible for any military payload to re-enter from orbit in three and a half minutes to the main centers of the USSR, a much shorter time than (a submarine-launched ballastic missile) could make possible (ten minutes from off the coast.)
The military very sensitive to the variety of possible means of delivering the first strike, suspecting that a first-strike capability might be the Vandenberg Shuttle's objective...
Hendrickx, Bart and Vis, Bert Energiya-Buran: The Soviet Space Shuttle, Springer-Praxis, 2007
p. 54
According to Boris Gubanov, Energiya-Buran chief designer:
The studies showed that the Space Shuttle could carry out a return maneuver from a half or a single orbit... approach Moscow and Leningrad from the south, and then performing a "dive" drop in this region a nuclear charge, and in combination with other means paralyze the military capability of the Soviet Union.

It wasn't a Transtage, it was a modified Titan 1st stage

PROPOSED GENERAL DYNAMICS-CONVAIR SHUTTLE DESIGN.
Prototype model with three 8-inch long shuttle vehicles attached together in launch configuration with a fourth 8-inch long shuttle displayed in landing configuration. All made from plastic and metal. A plastic 6 by 10 ½ inch base has a metal plaque that reads: "General Dynamics Convair Triamese Concept" along a raised section along the back edge. All shuttles can be removed from the display stand.
This is a model proposed in the early 1970s that would employ two outer vehicles as booster stages to allow the center section vehicle to achieve orbital velocity. All vehicles could land after use with deployable wings and air breathing jet engines. Presented to Dr. Faget during the NASA Shuttle proposal efforts.
Estimate: $4,000 - 6,000
Michel Van said:in 1980s were alot illustration of a "passengers Pod" for the STS
was that real project or only wishful thinking by some illustrators ?
blackstar said:There was actually a business proposal for that idea. However, I don't think it was serious. Not a real company with money. And a stupid idea.
Orionblamblam said:I can recall having a brochure or something on that. I *think* it was a Gary Hudson concept...

All the above designs were done for Aerospace/NASA, you can point to every shuttle in the images and know which design submission for the STS they were based on

A contact has just acquired the attached tunnel model from a retired Convair engineer's estate sale. We know nothing about it, but this might be a proposed weapons pod for the B-58 Hustler or a variant of. Have you ever seen it before, or do you have any ideas what it could be? The model is machined aluminium and measures 11 inches in length. My contact would greatly appreciate any help as to its identity.
SOC said:It looks similar enough to the shuttle idea that I'd be very suprised if it was something different. Pretty sure I've never seen anything quite like that among the B-58 weapon options.
