The 1959 Dyna Soar design from the Martin Company, designed by Hans Multhopp (formerly of Focke-Wulf). This was from when the Dyna Soar was a sub-orbital research vehicle meant to be lobbed by a modified Titan I ICBM. Note the inclusion of a turbojet engine for landing purposes, a common design element at this stage in the program.

Note that the cockpit of this little spaceplane was designed to be ejected in the event of an emergency. At this stage in the Dyna Soar program, the vehicle had lost its role as a bomber, and had been reduced to an R&D vehicle, thus the “cargo bay” stuffed full of equipment. Boeing’s final Dyna Soar design also had the instrument-filled cargo bay, but they fully expected to be able to ditch the instruments (which were mostly to measure and record pressure and temperature data all around the vehicle during re-entry) once the testing phase was over, and then proceed to fill the bay with useful payload, everything from anti-satellite hardware to passengers going to space stations.

The turbojet would very quickly be abandoned as weight climbed, meaning the Dyna Soar would glide to a landing much like the Space Shuttle.

A full-scale mockup of the cockpit was built… note that it appears to be made of cardboard. Cheesy, but perfectly adequate for preliminary layout purposes. Plus, some little kid may have gotten one hell of a spiffy Space Patrol Rocket to play in after its utility for Martin was finished. Note also the side-stick controller.

I keep getting asked the same questions, so I guess I should have a Frequently Asked Questions page for my downloads. Well, here it is.
Q01: How does this work?

A: It’s not an automated system. The way it works is that when you place an order through Paypal, Paypal sends me an email notifying me of the order. I then reply to the email address listed in the order, providing you with the web address where you can find your document, plus the username and password you’ll need in order to access it.

————–
Q02: “I just ordered a document. It’s been a whole 2 seconds, and I don’t have it yet. Where is it?”

A: I’m asleep/out buying groceries/fighting off hordes of zombies. I’ll respond to your email just as soon as I can.

————–
Q03: “I just ordered a document. It’s been a whole 24 hours, and I don’t have it yet. Where is it?”

A1: Check your “spam bucket.” Some spam filters see response messages such as you’ll get from me as spam, since there is a web address listed in it.

A2: Are you using the email address attached to the Paypal account? The response email with all your download info will be sent to the Paypal-listed email address. If you are using someone else’s Paypal address, or something like that, then *they* will receive the reply.

A3: On rare occasion, the automated Paypal system that sends me order notifications fails to do so. Thus I don’t know you’ve ordered something. Feel free to send a “where’s my stuff” email to:

A4: Search your inbox. You might have gotten the message, but not noticed or recognized it. The header will be something like “Re: Notification of payment received” or “Re: Payment received from YourEmail@YourEmailDomain.com.”

————–

Q04: “I ordered a document for downloading, but the username and password aren’t working.”

A: By far the most common reason for this is either you’re typing the password wrong… or if you are using cut-and-paste, you are grabbing a spurious blank space. Try again, making sure to cut *just* the password.

————–

Q05: “I tried that, but it’s still not letting me in.”

A: The second biggest offender is your web browser. Something or other to do with cookies, or something. If you have another web browser (Netscape, Explorer, Firefox, whatever), try that.

————–
Q06: “I’ve downloaded a PDF file. What do I need to open it?”

A: Adobe Reader. It’s a free program.

————–

Q07: “I’ve downloaded a ZIP file. What do I need to open it?”

A: Any modern computer should have come with an unzipping program built in. If not, do a search for “unzip,” and download a program to your liking.

————–

Q08: “I ordered a drawing set, and can see the files named ‘XYZ halfsize.gif’ and ‘XYZ quartersize.gif,” but not the full size image. Why?”

A: Some of the full size images are quite large. Sometimes they are so large that operating systems and/or image viewing and processing programs simply refuse to show them. All of the full-size images I sell are viewable on *my* system, which is a bit antiquated… but that doesn’t mean that they will be viewable on *all* systems. This is why I include the “halfsize” and “quartersize” versions, so that everybody should be able to see the images. You do still have the full-rez image… try looking at it on another computer.

————–

Q09: “Ooops, I ordered the wrong thing. I wanted A, but I seem to have actually ordered B. Can I have A?”

A1: If the error is due to something screwy in the webpage – rare, but it has happened that a typo in the HTML coding can lead to this sort of thing – then I’ll fix you right up with a proper download of A. Keep the other item, free of charge.
A2: A slightly more common error is on my part… you order SDOC4, say, and I mistakenly send you the link to SDWG4. In that case, let me know, and I’ll fix you right up with what you actually ordered. Keep the other item, free of charge.

A3: If the error is due to you simply ordering the wrong thing… well… the problem with digital files is that you can easily make copies of them, and thus cannot really be returned. So if my policy was to automatically “correct” “mistakes,” then it’d be the easiest thing in the world to scam me right out of half my catalog.

So… no. If you wanted A but mistakenly ordered B, I’ll be happy to fill your *next* order for A.

————–

Q10: “I bought one of your documents, and want to extract the images from it for my own devious purposes. However, it’s password protected. Gimme the password. Gimme.”

A: The documents (air docs, space docs and APr’s, but not DCD’s) are password protected *solely* to try to minimise piracy of ’em. The documents will open just fine and will print just fine at high rez, but image and text extraction will present a challenge. I’ve had issues with people taking the data I’ve worked hard to find and prepare and then turning it around and reselling it (grrr). However, if you have a valid use for extracted images, let me know, and I’ll almost certainly fork over the relevant password.

————–
Q11: “I want you to add me to your mailing list.”

A: No can do. The system I use now requires that the person who wants on the mailing list add themselves (I can add you, or the system will think I’m a spammer). So, simply go HERE and add your email address.

I’ll update this FAQ as questions come in. Feel free to comment

An early 1971 design from McDonnell Douglas for the Space Shuttle Phase B extension program. As an alternative to solid rocket boosters, this concept used a single liquid rocket booster underneath the external tank. Several concepts were studied, including pressure fed systems. This particular design used four F-1 rocket engines from the Saturn V, in an entirely new booster. The booster would be recovered at sea, splashing down nose first; large flaps would stabilize it nose-down during descent, and solid rocket motors would provide terminal deceleration.

At long last, Aerospace Projects Review issue V3N2 is now available.

The main article, about 90 pages worth, covers the Lockheed STAR Clipper concept.This was a one-and-a-half stage space shuttle concept. Starting in 1968 for the USAF, the concept lasted well into Phase B of the Space Shuttle program for NASA, and in altered form into the 1990’s. This article has a very large number of detailed schematics of many different forms, including the original small 1.5 Stage To Orbit design, numerous variations on that concept, fully reusable two stage versions with manned boosters, giant concepts for Solar Power Satellite logistics and miniature versions for the USAF in the 1980s.

Also included is an article covering antecedents and derivatives of the Northrop F-23 stealth fighter. Included are early designs such as the “Christmas fighter” and several “platypus” concepts, the F-23A operational fighter design, the NATF-23 concept for the US Navy with aft mounted wings and canards, the single-engined Multi Role Fighter (from the competition that led to the F-35) and perhaps most interestingly, the F/B-23 regional bomber, of eBay infamy. This article is illustrated with a mix of photos of official Northrop display models, official Northrop diagrams, all-new scale diagrams and color artwork especially commissioned for this article.

Dennis R. Jenkins provides an article on a Convair concept for converting the F-106 interceptor into a small supersonic transport. Compare this to Convair idea of converting the B-58 Hustler into an SST!

And finally, two aerospace history “nuggets,” the Vanguard Model 18 VTOL transport and a Northrop laminar flow control multipurpose long-duration aircraft.

In 1957, Darrell Romick of Goodyear produced the “Meteor Jr.”  design for a three stage fully reusable manned launch vehicle, a smaller version of the “Meteor” design from 1954. The designs were straightforward, with simple but gigantic delta wings.

As with other, similar designs of the period, such as Werner von Brauns “Ferry rocket” and derivatives, the math behind the performance of the Meteor Jr. was sound. However, like those other designs, the physics underlying re-entry would have trashed the Meteor Jr. Thin sharp wings made out of steel simply cannot withstand the aerothermal heating. Additionally, the large bubble canopies would have been at best problematic.

The Air & Space Museum Udvar-Hazy facility has a Goodyear display model of the Meteor Jr. vehicle on display.

A few examples of models and mockups of different versions of the Dyna Soar:

A few years back I got to poke around a little bit in the NASM Garber facility. Lighting was not the best and some areas were photography-discouraged, but there were a few things that I got some photos of. One was a large model of an early Boeing Dyna Soar configuration. It may have originally been a wind tunnel model that was repurposed into a display model, or it may have been a display model from the get-go (kinda big, though).

————–

One of Boeings earliest Dyna Soar designs, the Model 814-1012, dating from about March, 1958. Terribly ’50′s in design, looks like a hood ornament. All angles and fins, including two ventral fins which would have had a hell of a time surviving re-entry. This image is made from two separate kinda blurry photos of presumably the same display model.

———

Mockup and display model photos, circa 1960. Taken from a mockup review film.

———

A photo of a Martin corp. display model showing an early Dyna Soar/Titan III configuration. The Titan III would lose the fins after testing showed that the thrust vectoring capability of the Titan III’s UA-1205 booster rockets was up to the task of countering pitch moments produced by the Dyna Soar.

Parts of this were originally posted HERE, HERE, HERE and HERE.
