The Vought Hypervelocity Missile program began in the 1980’s as an effort to create a relatively low-cost anti-armor missile. Instead of a massive warhead, the HVM would use kinetic energy to simply punch a hole through the armor of Soviet tanks. it would do this by accelerating to in excess of Mach 4. The HVM program continued on in several modified forms into the 21st century, but eventually did not result in production.

A recent pile of stuff purchased on eBay included two Vought prints of the HVM, one showing either a test round or a mockup, the other an artists concept showing an armored vehicle with a large turret for the storage and launch of HVMs, in the process of ruining the day of the crews of two Soviet T-72s. Sadly the prints have seen better days, having gotten a bit crumpled over the years, but they’re better than nothing. I have scanned them in full color/300 DPI and uploaded the scans to the 2019-02 APR Extras folder on Dropbox, available to all APR Patrons and Monthly Historical Documents subscribers at the $4 level or higher.

PDF Review: L’Aeronautique, post-Great War

Jan 282019

The Internet Archive has a *lot* of stuff. One thing there is a scan of the French-language aeronautical magazine “L’Aeronautique” covering 1919-1921. It is available in a number of formats, including PDF, here:

https://archive.org/details/la02b9eronautiqu03pari/page/n2

Included in this is a design for a truly gigantic aircraft with a wingspan of 110 meters, produced by Professor Junkers, presumably Hugo Junkers of Junkers Flugzeug- und Motorenwerke AG.Hugo was an innovator in the field of all-metal aircraft construction, including the first practical all-metal aircraft the Junkers J 1 from 1915. The giant aircraft would have a wing area of 1,400 square meters and a gross weight of 60 tonnes; 12 engines would produce 4,000 horsepower and drive six propellers. Two tractor props would have a diameter of 6 meters, while four pusher props would have a diameter of 3.7 meters. No performance data seems to be given, but it can be assumed that it was meant to be a long range passenger or cargo transport.

Bonus: A helicopter design from one Douglas Shaw. This would have failed entertainingly.

Space Station concept art

Two pieces of NASA-marked (but likely not NASA-produced) concept art from the 1960’s depicted artificial-G space stations.

The first station (previously presented here in black and white not so long ago) depicts a substantial three-armed station witha multi-segment spine and three habitats. At one end of the spine is a nuclear reactor and its radiator; at the other end is a presumably rotationally0decoupled docking section. There is also an external “track” with two cars seemingly to provide transport from one habitat to another; it doesn’t really seem like this would provide a substantial improvement in transport over simply taking an elevator from one hab up to the spine and then down another elevator to the destination hab.

This space station, which appears from the art style to be a Grumman design, is a single-launch space station to be launched atop a Saturn V. The two arms would fold back for storage on the launch vehicle and would deploy once in orbit. An Apollo CSM is shown approaching for docking along the centerline; it’s not clear if the docking cone was rotationally decoupled. if it was not, the two Apollo-like capsules hanging off the sides of the cone are a bit of a head scratcher.

Both renderings have been uploaded in their full resolution to the 2019-01 APR Extras dropbox folder. This folder is available to APR Patreon Patrons and APR Monthly Historical Documents Program subscribers at the $4 per month level and above.

A Dramatic Reading

Dec 222018

So, *this* story continues to stumble along. There was a phone call between a content creator and the person responsible for the situation; a transcript of the call was somehow made. And while a transcript is fine, a recording of the call would be better. But the demand was made at the top of the call that no recording of the call was allowed. So, the next best thing: a dramatic reading of the transcript. note: you may scare your pets laughing at this.

Dec 182018

For some years I have been operating the “Aerospace Projects Review Patreon” which provides monthly rewards in the form of high resolution scans of vintage aerospace diagrams, art and documents. This has worked pretty well, but it seems that perhaps some people might prefer to sign on more directly. Fortunately, PayPal provides the option not only for one-time purchases but also monthly subscriptions. By subscribing using the drop-down menu below, you will receive the same benefits as APR Patrons, but without going through Patreon itself.

PDF Review: “Neptun,” the German Heavy Lift Launch Vehicle

Dec 042018

In the late 1960’s H.H. Koelle of the Technische University Institut Fuer Raumfahrttechnik in Berlin devoted considerable effort to studying a reusable heavy lift launch vehicle. A good, well-illustrated report was put out in 1968 covering the design:

Entwurfskriterien fur groBe wiederverwendbare Tragersysteme (Design Criteria for Large Reusable Space Transportation Systems)

Note that the Neptun was *gigantic.* It was a two-stage ballistically recovered design, unusual in that rather than being circular in cross-section it was hexagonal. The individual propellant tanks were each the size of or bigger than the S-IC first stage of the Saturn V.

A number of payloads were proposed. One was a sub-orbital intercontinental passenger transport, The passenger “capsule” would land separate from the Neptun itself.

One of the more interesting payloads contemplated was a large Orion nuclear pulse vehicle, transported in two pieces (propulsion module in one launch and payload/pulse units in the other). Presumably this would be a NASA Orion hitching a ride on a West German booster; I suspect politics would have negated the likelihood of the West Germans developing a mass production line for nuclear explosives.

This fusion-powered interplanetary spacecraft is also a NASA design, dating from the early 1960’s.

Bell STOL transport art

In 1972 Bell designed a STOL jet transport, a concept that competed for the Advanced Medium STOL Transport role that the McDonnell-Douglas YC-15 and the Boeing YC-14 were built for. The Bell aircraft appeared to be largely conventional in layout, but it was actually quite different from every other transport: the engine nacelles were not only fitted with Harrier-like thrust vectoring nozzles to redirect the core exhaust, the flow could be diverted from the fans to augmenters in the wings. These, it was hoped, would greatly increase static thrust, allowing the aircraft to lift off from unimproved runways in a short distance. As part of their proposal, Bell also designed a proof of concept demonstrator to be built from parts of a C-130. The demonstrator could itself be used as a fair cargo transport, though of course it would not be as well optimized as the all-new vehicles. Unfortunately, the augmenter-wing concept for vertical thrust turned out to be a major disappointment as it steadfastly refused to scale up well.

The demonstrator was recently diagrammed and described in detail in US Recon & Research Projects #03, and the operational version in US Transport Projects #08.

Shuttle Program Orientation Course

Nov 052018

In June 1973 Rockwell put together a short course – presumably or employees new to the STS program – that described the Space Shuttle system as it was then designed. There were a number of clear differences between the STS of the time and the STS as actually built. Differences included a forward extension of the OMS pods, continuing well onto the cargo bay doors. Also, the forward RCS thrusters on the sides of the nose were contained behind sizable doors to protect them during re-entry, a protection that was found to be unnecessary. There were also important differences with the SRBs and ETs.

I have made the full-rez scan of the document available to $10+ APR Patreon patrons. If this sort of thing is of interest, please consider signing up for the APR Patreon.
