I remember reading in an Old AWST (1970?) about a Rockwell proposal for the Phase B (TSTO) Shuttle which involved BAC work on the booster stage.

Does anyone have more info on this, or was it one of those 'briefly floated' ideas that sink beneath history's waves - never to be seen again?

The Final McDD and NAR Shuttle Proposals from

http://www.flightglobal.com/PDFArchive/View/1972/1972%20-%201737.html

Note, that according to the link the NAR Shuttle has abort boosters attached to the shuttle wings - and a thrust termination device at the nose of each SRB.  :'(

Hi,

the Grumman two-vehicles (booster and orbiter) concept,I think it
is a big surprise to me and you.

Hi,

a flight impression of NASA space shuttle.
http://www.flightglobal.com/pdfarchive/view/1968/1968%20-%201653.htm

This image depict, obviously, some FDL concept (as a sort of "deformed FDL-5") clearly recognizable are the vertical launch assembly, the two jettisonable tanks (as X 15ish style) and the folded wings extracted just prior landing.

Anyway this is the first image, I've ever seen, that is depicting an FDL mission.
Many thanks Hesham for this interesting contribution about the matter... :D

Not Grumman. Maxime Faget's "DC-3" concept.

Hesh,

Good guess, buddy. But it's already been covered in over Postwar. Check it out:

An to all those interested to heard from the very people that designed,build and operated the Space Shuttle, here is the link to the complete lectures as part of the MIT OpencourseWare.

These are 20+ lectures, each 1:30+ long. It was quite remarkable to hear them.

Hello!

I knew that Shuttle used a solid-fuel upper stage, the IUS. At the other end of the performance spectrum, used of the Centaur was stopped only by the Challenger disaster
(frightening story here http://space.co.uk/Features/Newsletters/200811November/FlightsoftheDeathStarPage1/tabid/628/Default.aspx)

But the Agena is new to me
http://ntrs.nasa.gov/search.jsp?N=0&Ntk=all&Ntx=mode%20matchall&Ntt=shuttle%2Fagena

After storable propellants would nicely fit the performance gap between solid and cryogenic fuel...

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).
http://en.wikipedia.org/wiki/Monomethylhydrazine
http://en.wikipedia.org/wiki/Dinitrogen_tetroxide
safe storable propellants

the Agena used fuel is UDMH , which is oxidized with Inhibited white fuming nitric acid
http://en.wikipedia.org/wiki/UDMH
http://en.wikipedia.org/wiki/White_fuming_nitric_acid
the oxidizer tank need protective metallic fluoride coating !
Quote
Being a powerful oxidizing agent, nitric acid reacts violently with many organic materials and the reactions may be explosive
something you don't want in a Shuttle cargobay in case the oxidizer tank, feedline or valve leaks

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)
