Grumman shuttle/Saturn concept

From 1970, a Grumman Alternate Space Shuttle design that utilizes the S-IC booster from the Saturn V. Quite a number of Space Shuttle concepts called for the S-IC to be used as a first stage booster, as an expendable stage, a partially reusable or fully reusable stage. Shown here, the basic S-IC would be expendable. However, a second option would be to use a modified S-IC where the outer four engines would drop off during ascent and would be recovered. This is the same concept that Boeing proposed for the S-ID stage (see the October 2008 issue of the AIAA-Houston “Horizons” newsletter for more on the S-ID).

The use of a S-IC – stock or modified for partial recovery – would have presented a number of advantages, not least being that the existing Saturn launch facilities could be used. The S-IC would have provided adequate launch performance; the use of recoverable engines would have lowered cost and increased performance. However, the S-IC production line had been shut down for some time, and restarting it would have proven not only politically dubious (restating the S-IC would have led to questions about restarting the rest of the Saturn/Apollo line), but also expensive.

Early Convair Space Shuttle

In October of 1969, General Dynamics/Convair reported to NASA on their Space Shuttle design work. This included a series of vehicles that utilized boosters and orbiters of similar geometry… basically little more than flat-bottomed aeroshells wrapped around the oxygen and hydrogen tanks. Both the booster and orbiter used turbofans stowed in the nose for flyback, and high aspect ratio variable geometry wings.

A number of configurations were studied, including triamese configurations with two boosters that had considerable commonality with the orbiter, to two-stage systems with entirely different boosters and orbiters. Payloads studied ranged from 25,000 pounds to 50,000 pounds. Note in the scale drawings below that the 50K version was virtually the same size as the Saturn V. This was due in part to the all-hydrogen fuel, and part as a consequence of reusability.

North American Hypersonic Transport

Conceptual artwork from 1967 depicting a Mach 10 to Mach 14 hypersonic transport. Hydrogen burning scramjets would provide cruise propulsion at an altitude of 110,000 to 140,000 feet. No further data is available apart from what can be determined from the artwork. There are 136 seats, relatively few for an aircraft that is clearly quite large. The general configuration is similar to the hypersonic testbed previously posted HERE, especially the propulsion system & inlet arrangement.

You can download a 9.7 megabyte JPG file of the artwork; the link is HERE. To access it, you will need to enter a username and password. The username and password are listed on page 2 of APR issue V0N0. Note that both are case sensitive.

Martin Dyna Soar Details

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.

BAT in Hi-Rez

A publicity photo of the BAT (Bell Advanced Tiltrotor), a circa 1984 concept for a one-man attack tiltrotor to complete in the Army scout helicopter program (LHX – Light Helicopter Experimental) that led to the abortive RAH-66 Comanche. Shown here is a full-scale mockup; the prop-rotors as shown are substantially chopped down from the length they’d be on the actual aircraft. The BAT would have outperformed all other competitors except for hover performance; but the Army did not want a fixed-wing vehicle, so the BAT did not progress very far in the competition.

You can download a 3 megabyte JPG file of the artwork; the link is HERE. To access it, you will need to enter a username and password. The username: the first word in the body of the text on page 6 of APR issue V1N3. The password: the first word in the body of the text on page 23 of the same issue. Note that both are case sensitive.

Early “Sea Launch” Concepts

Jan 262012

A Boy Scout booklet on making models (printed sometime in the 1980′s or later, but was originally printed in 1964) contained a number of rather tiny black and white futuristic automobile, ship, aircraft and spacecraft artists concepts. Sadly, there were no notations as to who created the artwork. Several of the pieces I recognize as having been created for Real Projects by Real Companies or Real Government Organizations, so I assume that at least most of the ones I *don’t* recognize were also “real” projects, as opposed to, say, artwork created for Mechanix Illustrated.

Three of the illustrations show large ships preparing to launch large missiles. These can be safely assumed to be space launch rockets rather than ICBMs.

The first illustration seems to show an Atlas launch vehicle being launched off the back of a large ship… apparently a modified aircraft carrier. The payload on the Atlas has an escape tower… indicating that it’s a manned Atlas (perhaps Mercury). Oddly, the ship seems to be underway to judge from the wake. This seems unlikely, unless it’s a tactic to keep up with the wind. Chances are fair that this might be a Convair concept.

The second concept shows a smaller ship and a smaller rocket. Perhaps a Scout?

The third concept shows another large ship, heavily modified with what look to be armored domes. The rocket appears to be an Atlas-Centaur.There appear to be propellant tanks amidships… perhaps liquid hydrogen tanks. Again, chances are fair that this is a Convair concept.

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
