Artwork circa 1983 depicting the Bell BAT (“Bell Advanced Tiltrotor”… so… ummm… the “Bell Bell Advanced Tiltrotor”) single-seat small military tiltrotor designed to compete in the LHX program. It is shown here in two modes. The nearest aircraft is in full forward flight; the aircraft in the background is hovering. Both are in the process of firing unknown anti-tank missiles at a column of Soviet armor.
Some years ago I produced a range of cyanotype blueprints of a number of aerospace subjects. The hardware needed for this was disposed of when I left Utah at the end of 2019, so starting again seemed unlikely. However, someone has expressed interest in a special commission. Rebuilding the hardware needed will be an expensive chore, and sadly getting the large format transparencies printed looks like it will be much more difficult here than it was in Utah. Nevertheless, at this point it looks probable that I will restore that capability sometime in the next few months, assuming one further detail can be ironed out.
You can see my now-defunct catalog here:

When I get back to it I will probably focus on the larger format stuff rather than the smaller prints. I have plans on how to improve upon the prior hardware to make things work better and more efficiently. If there are any of the former large format prints you’d like to see returned to production, or you have any prints you’d like to see, let me know. And once this is up and running I plan on trying to take commissions, working with a local print shop to find customers interested in this somewhat unusual and certainly obsolete form of art.
If you have a diagram you’d like me to turn into a cyanotype, contact me. Commissions aren’t going to be restricted to aerospace subjects; naval, architectural, movie props, whatever you’ve got, so long as it *can* be blueprinted, once things are in place I should be able to do it. 
A Beech Aircraft Company concept for a civilian VTOL for the 1980s, from circa 1971. This would be a two-seater using tilt-ducts. This appears to be less “engineering” and more “art,” as there are some definite headscratchers about the design. Where are the engines? In designs such as these it/they are typically in the fuselage, driving the ducted fans with shafts. But no provisions for inlets or exhausts are evident. So the engines would probably be in the nacelles themselves but there doesn’t seem to be room for them. The cockpit canopy is expansive and would provide a *fantastic* view, but it seems to be sized only for people who have had their legs amputated. The configuration, unlike your average tiltrotor, seems perfectly capable of horizontal runway takeoffs and landings, but the use of skids rather than wheels would make that problematic. The disk loading would be impressively high, and the resulting blasts of air from the ducts would likely tear anything short of solid concrete to shreds.
The West German Weser Flugzeugbau revealed the design of the P 23 tiltrotor in 1963. This was to be a do-everything vehicle… civil passenger transport, cargo transport, troop transport, ground attack, flying crane. It was an attractive design with one turboshaft engine at each wingtip; the rotors tilted, but the engines were fixed. The engines also provided power to two smaller fans mounted in the tail for pitch and yaw control. Sixty years later, it still looks like it would fit well in the skies of today, and look futuristic doing so.
Twenty copies of the new book have finally arrived, fortunately entirely intact. They took two days to cross an ocean, one day to cross half a continent… and two weeks to cross the customs office. Shrug.
Anyway, here’s what I’m gonna do: signed, numbered and dated copies will be $20 plus postage (media mail). These will come with two 18X24 prints, also signed and dated. If you would like to be on the list for one of these send me an email: 
But the first five copies will be auctioned off, with the highest bids getting the lowest numbers. Additionally: numbers 3,4 and 5 will receive three 18X24 prints, while numbers 1 and 2 will receive four 18X24 prints, all signed, dated and numbered. If this sounds interesting to you, email me what your bid is. Bidding ends Sunday night, after which I’ll let bidders know. If there are more than five bidders, six and beyond won’t be held to their bids… but they won’t *necessarily* get the next numbers in line. Once the auction winners are processed, I’ll send out PayPal invoices for the regular copies, and they will be sent out based on the order of payment.
I also have ten “SR-71” copies and five “B-47/B-52” copies. The SR-71’s, singed and dated with two 18X24 prints, will go for $20; the B-47/52 signed and dated with three 18X24 prints, will go for $55 plus postage. If you would like one of these, let me know.
Early in the LHX program (gave birth to the late lamented RAH-66 Comanche) the Army’s requirements were sufficiently aggressive and vague that Bell Aerospace held out hope that a tiltrotor might be chosen. So Bell designed a few single-seat “scout” tiltrotors under the BAT (Bell Advanced Tiltrotor) moniker. Most were more or less similar in configuration to the Bell XV-15, but one design – which I know solely from this one piece of art, published in 1983 – went a little further. The fuselage and tail surfaces were shaped to reduce the radar cross section, making the vehicle hopefully somewhat stealthier. Sadly, no diagrams or technical information for this configuration. If someone knows more, or has a better version of this artwork, by all mean let me know.
The Vertol Model 107 became the Boeing Vertol CH-46 Sea Knight. It has been a fabulously successful helicopter; development began almost *70* years ago, and some are still in service.
One suggested modification from 1961 would have seen the helicopter (designated HC-1A at the time) modified into an anti-tank variant using wire-guided anti-tank missiles. The artwork depicts the Model 107 modified with a “trapeze” that would lower from the belly holding one such missile (appears similar to the SS.11 / AGM-22) ; after launching the missile the launcher would retract back into the cargo bay where it would be reloaded and redeployed. At the rear of the bay is a manually loaded rocket launcher (though it looks more like a recoilless rifle to me) that would, after loading, swing down into a forward-firing position. Further rocket launching tubes were built into the extended rear landing gear sponsons; machine guns were fitted ahead of the cockpit.
The Grumman Advanced Stealthy Penetrator (GASP) received a fair amount of exposure in the mid 1980’s by way of artists concepts published in aviation magazines and the like. Actual technical information has remained elusive; the total pile of artwork and photos of a display model would permit the creation of reasonably good layout diagrams, but dimensions and performance remain wholly unavailable. The GASP would most likely have been intended for strike applications rather than air supremacy.
Shown below is a PR image showing, presumably, a Grumman engineer at work on a 3D CAD diagram of the GASP. This image dates from no later than 1984, so the CAD system was a pretty early one (though by no means the *earliest* CAD system). It would be interesting if the files were still in existence and could be imported into a modern CAD system… but that’s not something I’d hold out a lot of hope for. Artists impressions that show the cockpit seem to indicate that this was a sizable vehicle, though such judgements are difficult to take fully seriously.
A bit short of a week ago I posted artwork of a “Boeing Advanced Fighter.” This led to the re-discovery of the actual model number 987-350 (I knew it some time back, but my brain is full I guess). And that led to the below CAD diagram, coming in just under the wire for a forthcoming book. The 987-350 was a tactical supercruiser; armament is unfortunately left a bit vague in the available documentation. The artwork depicts it with four folding-fin AGM-69 SRAM missiles; another diagram depicts it with two larger-diameter missiles of similar length. All were to be semi-submerged for low drag.
The National Reconnaissance Office is starting a series on the history of the Manned Orbiting Laboratory, a small space lab that was designed in the early/mid 1960s for the Air Force. Officially just a basic space lab, in reality it was an advanced (for the time) spy satellite. So far there is only Part One on the NRO website, and there’s not much to it… but we’ll see how it goes.
As a reminder, there is a whole freakin’ mountain of MOL documents on the NRO website:
