The YouTube channel “Found and Explained” just released a video on the 4,000 ton Orion Battleship, with the model used based on my reconstruction from issue V2N2 of “Aerospace Projects Review.” The video was sponsored by a “Star Trek” video game, so there are a *lot* of Star Trek references in the video.

For more information on the project, including blueprints, be sure to check out issue v2N2.

A Boeing concept from 1983 for an Orbital Transfer Vehicle. This vehicle would change the orbit of the payload not only propulsively, but by using aerodynamic drag to slow the vehicle at perigee. When returning a payload from geosynchronous orbit, it would dive into the upper atmosphere and use aerodynamic lift and drag to slow into a much lower orbit, with propulsive adjustments to put it into a circular orbit for rendezvous with a space Shuttle for recovery or servicing. This particular design was inflatable (creating a lifting body akin to a stretched-out “ASSET” shape) and used an extendable/stowable nozzle. Note that it is entering “upside down” so that the lift forces generated are trying to force it *closer* to Earth, rather than trying to bounce off the atmosphere.

 

Orbital velocities at geosynchronous are  slower than in low Earth orbit… about half the speed. So a relatively small change in velocity at geosynchronous will turn the circular orbit into a sharply elliptical one, with a perigee close to Earth. But that velocity at perigee is much faster than circular orbit velocity, so shedding speed using “free” aerodynamic forces makes sense… if you can pull it off.

Currently on ebay is an aluminum model of a lifting body. The rear of the vehicle is that of the M1 or M2, but the nose is distinctly conical. The lack of useful volume leads me to think that if this is a legit wind tunnel model (rather than something someone just knocked out at a machine shop for giggles), then it’s not a design for a manned vehicle, either test or operational space logistics. Rather it would be something like:

1) A basic subscale research vehicle like ASSET

2) A concept for a maneuverable entry vehicle for a military system. An ICBM warhead, perhaps designed to glide either for range extension, to avoid incoming ABMs, or to maneuver to avoid tracking systems and come in from unexpected directions.

3) Or it’s just a vague, generic “let’s look at everything” shape.

The nose of the model does not inspire a great deal of confidence… it looks a bit unfinished, with some sharp-ish corners that don’t seem like they should be there.

If anyone knows better, by all means speak up…

Bell artwork circa 1983 depicting the proposed JVX tiltrotor, which would become the V-22 Osprey. The cockpit and the sponsons display the greatest obvious differences from the aircraft that would eventually be built, but the design seems to be largely just about there.

A photo of a wind tunnel model of a Republic Aviation design for a Manned Hypersonic Test Vehicle configuration. The photo was published in 1969, but the program was circa 1965. It used a configuration previously studied as both an Aerospaceplane (airbreathing SSTO) and Mach 10 recon. That latter design was written about and illustrated in US Research & Recon Projects #2. You can tell that this is the subscale demonstrator, rather than one of the full-scale operational vehicles, because of the additional fuel tanks, projection from the lower fuselage. The fuselage was conical and ringed with a scramjet engine; a rocket engine in the tail would, after separation from a B-52 carrier aircraft, accelerate the vehicle past Mach 7 or so to scramjet operational speed.

Three magazine advertisements from 1960, depicting the East German Type 152 jetliner (which would have been a *fantastic* jetliner in the late 1940’s), the Convair F-106 and the Fiat G91 T jet trainer.

 

The full-rez scans of these ads have been uploaded into the 2022-10 APR Extras folder on Dropbox, available to all $4 and up APR Patrons/Subscribers.

Here’s a look at Book 4. Some of the diagrams I do are completed in just a few hours. Some take considerably longer… several to many man-days, sometimes spread out over months as I dial in details. This one was sort of mid-range. The most complex and time consuming are typically the diagrams of aircraft that were actually built… those have to be accurate, and more details are available. This one is of an unbuilt aircraft that is reasonably well documented, but was a configuration that was in a constant state of design flux.

Art from 1966 showing the S-IVB stage as launched on the SA-203 flight of the Saturn Ib, launched July 5, 1966. This flight put an S-IVb stage into orbit and demonstrated engine restart in microgravity, needed on the upcoming Apollo moon missions.

Photos of a physical copy, fresh from the printer, somewhere in the wilds of Britain. UK/EU buyers should start receiving them shortly, I’d imagine.

The ordering link straight from the publisher:

US Supersonic Bomber Projects

And the updated Amazon link:

US Supersonic Bomber Projects Paperback – December 23, 2022

As previously mentioned, if you are interested in a signed, dated and bonus-print copy, let me know so I know how many to order.
