Are there any unclass pictures or drawings of the BETA and BETA II spaceplane study from the 1980's. I'm working on another project and I tried the search engine. The only images I found were the Beta SSTO from, and (shaking my head 'no') "Blackstar". IIRC, The BETA I'm looking for was part of a project called Science Realm.

Not this one...these ones...

The Aeropropulsion Analysis Office of the NASA Lewis Research Center was studying
propulsion systems for possible low-risk replacements for the space shuttle. This study focused its work on a
smaller version of an Boeing / USAF two-stage-to-orbit (TSTO) concept called Beta.

The NASA concept, Beta II, is to deliver 10,000 pounds to low polar orbit. (The original Beta vehicle is sized to delivered 50,000 pounds.)

Also. BETA. Wind tunnel config. tested. As far as I can remember, in an AEDC tunnel. Better res image may even have been released in an AEDC leaflet. Saw that once, a long time agao...

Regards

More.

BETA explored various types of potential upper stages, including a manned "mini" space shuttle, and "air-launched" X-30 / Nasp.


By the way, BETA puzzled me a lot and I would be grateful to anyone of you who would be able to tell why the project was called BETA. Was STS (aka Space Shuttle) ALPHA? For those who can remember in the early 1980s, the "space station" (yet to become ISS...) was sometimes refereed to as ALPHA, then Freedom, etc.

Confirmed. BETA stage separation effect color image taken from AEDC brochure.

Weird. Looks like BETA but I can't relate it to other published material. Looks like student work or publicity...

I'm fairly certain all of the images in the thread are BETA II configurations. I've never seen a BETA image in the public domain.

According to the BETA-II history paper the BETA design is the one with the T-Tail but never really proceeded beyond a vesability study. The AF changed the parameters and re-issued the contract for the BETA-II and that became the more published and illustrated version it would seem.

Very nice. Was this related to the german SSTO projects, also called Beta ? by Dietrich Koelle ?

This BETA reference above is a series of horizontal takeoff TSTOs originally developed by Boeing and the USAF Flight Dynamics Laboratory. There are references upthread, including the Boeing patent, and a historical overview is provided in Draper and Sieron, "Evolution and Development of Hypersonic Configurations, 1958-1990", which covers the Air Force lineage.

There were five booster evolutions, starting with a twin body Beta 0 that was reminiscent of the Martin Marietta Space Shuttle twin-body reusable booster, all the way through Beta 4, which is shown in the Boeing artwork. The design goal was near-term deployment, so propulsion was based on derivations of existing turbofans with integrated ramjets, and an SSME to get to the Mach 8 staging point.

There were at least two USAF orbiter evolutions, a cone-shaped SSME-powered vehicle and the later FDL-derived design, also shown in the Boeing artwork.

NASA Langley developed a slightly different evolution of the orbiter, with more of a wing-body design as you would expect from Langley. The payload was also smaller, 10,000 lbs. to orbit, while the original USAF requirement was 40,000 lbs. to polar orbit.

No - as the Astronautix entry already indicates, Koelle's BETA is the German acronym for Ballistisches Einstufiges Traeger-Aggregat (literally translated ballistic single stage carrier unit [or more correctly launch vehicle]).
