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

Nova Class III in Hi Rez

launch vehicles, spacecraft 4 Responses »

Jan 112012

The Class III designs for Nova were intended to use advanced propulsion systems, advanced materials and be fully recoverable. Shown below is a NASA briefing chart on Nova Class III designs from September 1963 showing three Class III designs. The first is an airbreathing SSTO concept… a conical vehicle with rocket engines at the rim, and a ;large duct wrapped around them. This produced an ejector effect, in theory greatly increasing thrust at low airspeed. As velocity increased, fuel could be injected directly into the duct, turning it into a ramjet. The ramjet would of course be use for only a relatively brief portion of the flight, so the duct would be dropped not long into the flight, presumably to be parachute recovered in the ocean. The other two designs are substantially more conventional, though both used plug cluster engines.

You can download a 4.4 megabyte JPG file of the artwork; the link is HERE. To access it, you will need to enter a username and password.

NASA artwork from September of 1963 illustrating two configurations for Class I Nova designs. The Class 1 designs were the lowest-technology of the three classes suggested, and involved the use of expendable vehicles and conventional propulsion systems.

Still, the Nova designs were sized to carry payloads of a million pounds or more, about four times that of the Saturn V.

APR issue V3N2 Addendum now available

bomber, fighter, launch vehicles, space shuttle, stealth 5 Responses »

Dec 172011

APR issues used to be published with a mishmash of of 8.5X11 and 11X17 pages. When I started releasing issues on MagCloud, APR became an all-8.5X11 publication.

However, there are oftentimes illustrations that would benefit from being on 11X17, such as many in issue V3N2. Additionally, there are often more illustrations than can be conveniently added to a coherent article. So I have put together an addendum for V3N2, including a number of larger-format illustrations and some new ones that didn’t make it into V3N2. This includes:

1/72 scale CAD drawings from the F-23 derivatives article (they were 1/144 scale in V3N2)
1/96 scale CAD drawings of the FB-23 (formerly 1/144 scale)
Larger-size and additional color renderings of the F-23A and NATF-23 by artist Ken Scott
Larger-size versions of the “Christmas Fighter,” YF-23, F-23A and NATF-23 diagrams
Larger-size and additional diagrams covering the STAR Clipper and derivatives

The V3N2 Addendum can be downloaded directly from me for the low, low price of $5. To get the download, simply pay for it here through paypal.

McDonnell Douglas series-burn booster for Shuttle

launch vehicles, space shuttle, spaceplane 1 Response »

Dec 132011

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.

Rockwell Shuttle Model Drawings

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.
