Now available: two new US Aerospace Projects issues. Cover art was provided by Rob Parthoens, www.baroba.be

US Bomber Projects #20:XB-59 Special

US Bomber Projects #20 is now available (see HERE for the entire series). Issue #20 collects all the previously published articles and diagrams of the XB-59 antecedent designs and updates them. Additionally, more antecedent designs have been included as well as several designs that followed along after the XB-59. The biggest USXP publication yet!

USBP 20 includes twenty nine unique aircraft concepts (the usual issue of USXP has eight designs) from Boeing Models 484 and 701 showing how Boeing evolved the XB-59, their competitor to the Convair B-58 “Hustler.” Beginning with subsonic flying wings, the concept saw concepts both conventional and unconventional before eventually settling on Model 701-299-1, the final XB-59 design. This issue includes a half dozen Model 701 designs that followed along after the cancellation of the XB-59 program.

USBP #20 can be downloaded as a PDF file for only $8.50:

Dyna Soar on an Atlas

A rare piece of color art of an early Dyna Soar being lofted atop an Atlas/Centaur. Color artwork of the Dyna Soar was created in some considerable abundance, but it was mostly reproduced in B&W, and its sadly rare for even those B&W reports to have been printed well, rarer still for them to have been scanned or copied well.

As a followup to the photos of the H-33 display model, here’s a Grumman report from July, 1971, giving a pretty good and well illustrated description of the H-33 orbiter.

The abstract on NTRS can be seen HERE.

Grumman H-33 Shuttle Orbiter: plexiglas cutaway model

hi-rez, hypersonic, launch vehicles, Patreon, rockets, space shuttle, spacecraft, spaceplane No Responses »

Aug 122017

The H-33 orbiter was designed in early 1971 to be launched atop a reusable manned flyback booster, a truly giant supersonic vehicle. The orbiter itself was similar in configuration to the Shuttle Orbiter as actually built, but it differed in that it had internal liquid oxygen tanks and expendable external hydrogen tanks, rather than a single large ET. The NASM has some good photos of a display model of the full system.

The H-33 was a popular design, at least at Grumman. A number of display models were made of it, including this detailed “cutaway” model made – seemingly – of plexiglas.

I have uploaded the full-rez images to the 2017-08 APR Extras Dropbox folder, available to all $4 and up APR Patrons. If interested, wander on by the APR Patreon and sign up. Lots of aerospace goodies available.

PDF Review: X-20 Dyna Soar Progress Report

Seems I’ve been a wee bit lax on the PDF Reviews I will attempt to rectify that in the future.

Here is a Air Force conference paper from May, 1964, describing the X-20 Dyna Soar program and vehicle. At this point the program had been cancelled for some months; the configuration shown in the paper was essentially the final design. It’s a decent overall view of the Dyna Soar.

Here’s the link to the abstract:

Plexiglas AeroSpacePlane

Jul 042017

Around 1960, the USAF had high hopes for the development of ASP: “AeroSpace Plane.” ASP was a program to develop an airbreather one- or two-stage-to-orbit spaceplane. The first stage would use some form of Liquid Air Cycle Engine; the inlet would be actively cooled by the liquid hydrogen fuel so that the incoming air would be condensed to liquid, which would allow the liquified air to be stored and fed into high chamber pressure rocket engines. ASP was extremely ambitious, and obviously – since no airbreathing system has made it to orbit (not counting simple turbojet-powered aircraft carrying otherwise conventional rockets such as Pegasus) – it did not work. A fair chunk of change was spent on the concept, but it faded away after a few years. The basic idea of ASP would arise a quarter century later with NASP, to similar levels of success.

A good, well-illustrated article on ASP was published some time back in issue v2N5 of Aerospace Projects Review.

Most of the known ASP designs were produced by Convair. It seems that Convair jumped into the program with both feet, producing not only detailed diagrams of a whole range of vehicles but also artwork and display models. And the latter category included some beautiful see-through models made from Plexiglas. It shows some interior details such as the complex plumbing of the Liquid Air Cycle Engines, as well as the winged second stage tucked into the lower fuselage of the very large hypersonic first stage. In an era long before computer animation, models such a this would be very useful in illustrating complex concepts to customers and bosses.

I have uploaded the full-rez version of this photo to the 2017-07 APR Extras Dropbox folder, available to all APR Patrons at the $4 level and above. If you are interested in accessing these and other aerospace historical goodies, consider signing up for the APR Patreon.

Hypersonic testbed

Dating from about 1963-63, this is a depiction of a high-altitude research aircraft equipped with “composite air-augmented turbo-jets” for launch and rockets for “near-space operations.” The general configuration was used many times over the decade, typically for scramjet powered aircraft. This was painted by Pat Shealy, chief of the Presentations Division, Air For Office of Scientific Research at Wright-Patterson Air Force Base.

So very, very close on the next two US Aerospace Projects issues. I’m only lacking cover “art”and have to deal with a bit of “dead air” in the middle of US Transport Projects #7. Usually I can shuffle things around well enough to not have this sort of thing, but this time it just hasn’t worked out. I suppose it doesn’t really matter all that much, but it does look kinda lazy like that.

It’s been about a year since I released the last USxP issue. That last issue was the first time where I used vector diagrams embedded within the issue, rather than raster images; getting the diagrams from AutoCAD into Word was a bit of a chore back then. And in the intervening months… I forgot how I did it. So I had to figure it out again, and the process is different. I have to walk the AutoCAD diagram through Rhino 3D and save as a WMF and blah, blah, blah; end result is it works just fine. I’ve done some further refinement… the main outlines are set at 0.25 mm width and the ends of the lines have been reset to rounded and mitered, so sharp corners now look more like sharp corners.

Hoping to have these two out in a day or two. The other three will be rather longer.
