Bell BAT LHX art

Dec 192022

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.

Beech VTOL: 1971

Dec 032022

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.

Weser Flugzeugbau WFG-P 23 Tiltrotor

Dec 022022

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.

Bell Super Transport Artwork

The Bell 214ST (“Super Transport”) first flew in 1977. Derived from the Bell 214, itself derived from the UH-1 “Huey,” the 214ST was substantially bigger and more powerful than the original design. Bell had great hopes for the type, but in the end less than one hundred were produced. A not-inconsiderable part of the problem was that the 214ST was designed to be produced in Iran which, at the time, was an American ally; of course, Iran soon fall to forces of the Stupid Age, and that put an end to notions of Bell designs being manufactured in Iran. It was roughly similar to the Sikorsky UH-60 in size and performance. Bell continued to push for customers into the 1990’s (the art below was published in 1982), but production ended in 1992 without any big contracts.

The full rez scans have been uploaded to the 2022-11 APR Extras Dropbox folder for $4 and up Patrons/Subscribers.

Bell LHX tiltrotor: Stealth edition

VTOL No Responses »

Nov 272022

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.

Anti-tank Vertol 107

Nov 242022

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 most recently finished diagram took several days. The references were clear and detailed… and difficult to suss out in some ways, a common issue with aircraft that had deployable bits.

JVX Art

Oct 252022

Bell artwork circa 1983 depicting the proposed JVX tiltrotor, which would become the V-22 Osprey. The cockpit and the sponsons display the greatest obvious differences from the aircraft that would eventually be built, but the design seems to be largely just about there.
