The first US Aerospace Projects in *years* is now available. Cover art was provided by Rob Parthoens, www.baroba.be

US VTOL Projects #3

US VTOL Projects #3 is now available (see HERE for the entire series). Issue #2 includes:

  • Lockheed CL-579: An optionally-manned “communications satellite” for after WWIII
  • Vanguard Model 18: A short range passenger transport from the 60s with slightly unusual wings
  • Hiller STORC: A helicopter that could convert into a conventional aircraft for long-range ferry flights
  • North American Rockwell NR-356 Sea Control Fighter: The design that led to the failed XFV-12A
  • Bell D181: One of the first VTOL “assault transports”
  • Hiller Anti-Submarine Warfare Drone Tailsitter: An unmanned pulsejet-powered torpedo-launcher
  • Gates Twinjet: An ill-timed executive transport helicopter
  • McDonnell Douglas VT107-4-4I: A short-range VTOL jetliner from the early 70s

While this issue covers the usual eight designs, note that it’s about 50% longer than similar, earlier issues. The delay in publication was due in large part to working on several book… and working on several books seems to have led me to be more verbose in my descriptions. So hopefully this means a better product!

After a delay of several years, I’m back to working on my own little publications. Since the delay was caused by working on actual published *books,* I like to think that I’ve gotten a bit better. Thus the next issue of US VTOL projects has about twice the text of the prior issue, and the diagrams are a bit better. To get best use of the diagrams, I’m reviewing how they are being incorporated into the final text. The link below is a test PDF with four pages… each page has the same illustration, but with variations in resolution, line weight, etc. I’m interested in what looks “best.” So take a look and let me know which page – if any – looks best on screen, and if possible printed out.

A 1969 Bell  Helicopter design for a high speed stowed-rotor tiltrotor. This was meant for USAF search and rescue and featured gun turrets fore and aft (each with a Minigun) and four turboshaft engines under the wings. Doubtless the gearing from the engines up through the pylons and along the wings to the nacelles would have been an engineering nightmare. But if it worked, it would have resulted in a tiltrotor with the hover performance of the V-22 and a cruise speed of 400 knots.

An article on the similar D270-900-112 (the main visual difference being that the engines were separately podded) was included in US VTOL Projects #1.

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

A few decades before the “X-Wing” configuration gained a measure of popularity, Hughes Tool Company made a detailed study of a somewhat similar concept, the “rotor/wing.” This was a three-bladed helicopter rotor attached to a large central lifting surface, either a circular disk or a triangular structure. The rotor was not turned the conventional way with a turbine engine turning a drive shaft, but instead the engine exhaust was ducted through the center and then out to nozzles at the tips of the rotors. Jet thrust would spin the rotors without transmitting torque to the rest of the vehicles; as a consequence only a small tail rotor would be needed, just powerful enough to orient the craft at low airspeeds.

A few configurations were produced, most of which looking much the same. Probably the most well known configuration was shown in US VTOL Projects 01. Shown below is a lesser-known configuration designed for anti-submarine use. Normally the configurations included the turbojet engines within the upper fuselage, close to the hub of the rotor, but this one rather bizarrely put the engines on the tail. No obvious means of ducting the exhaust to the rotor is evident, so presumably a third (or even fourth) engine was tucked into the fuselage somewhere.

The Lockheed AH-56 Cheyenne was without a doubt the niftiest helicopter ever to *almost* make it into production. but, alas, it was ahead of its time… more precisely, ahead of the available technology.

The gunner sat in a seat that could spin 360 degrees (like the gunner in the Gunstar… and if you don’t get the reference, you’ve a geekiness deficiency). The Cheyenne had a pusher prop for very high speed for a helicopter, and small wings to generate lift and offload the rotor at speed. Lockheed had considerable faith in the future of that propulsion concept and incorporated it into designs for civilian passenger transport helicopters such as the CL-1026 9described in US VTOL Projects issue #01).

I admit that the USBP series looks kinda… bland. It’s text and line drawings; not a whole lot can be done to jazz that up. Especially since I have no head for graphics design whatsoever apart from layout diagrams.

Still, one reader sent me a mockup of a revised cover of USBP #18:

USBP18blue

Things are moved around a little bit, but the obvious change is the addition of color. The suggestion was also made to consider color-coding each title in the USXP series. Just off the top of my head, I came up with:

Bombers: Olive Drab

Spacecraft: Black

Launch Vehicles: Blue on bottom, transitioning to black at the top

Fighters: slightly bluish gray (like the F-15 or F-22)

Transports: ??

VTOL: ??

The USBP#18 cover was re-done to reflect this, thusly:

USBP18green

Thoughts? Is this more appealing?How about color-coding… good idea or not? And if so, what colors?

I tried something vaguely like this once before, with USBP#05.

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
