HUGHES PROTOTYPE MODEL XV-9A HOT CYCLE HELICOPTER

From estate of late military helicopter test pilot and holder of Sikorsky built helicopter speed record comes this unique-one of a kind- sturdy resin model on heavy aircraft grade aluminum plinth, with terrain finish. Please check out enclosed link showing the actual prototype. I believe only one was ever built and it was basically a patchwork piece assembled with parts from other military aircraft. The “Hot Cycle” technology did not pan out and the aircraft was never put into production. This model purchased from test pilot’s son in Southern California, shows an obviously different design in the rotor and tail structure as well as the placement of the engines. Therefore my one of a kind claim. I will let my pictures do the talking, should you need more………no problem…I will need your email address included with request. The piece will weigh 11 lbs including packaging and will be disassembled for safety in transit. The plinth and arm are the heaviest parts of the unit.

Note… this is *not* a model of the XV-9. That was a helicopter that actually flew, using the “Hot Cycle” system… turbojet exhaust was ducted through the central into the hollow mast, through the hub, and down ducts through the rotors to nozzles at the tips. This would spin the rotors without the need for a direct mechanical drive, eliminating most of the torque that conventional helicopter drives produce – and thus eliminating the need for a tail rotor. While in development, Hughes engineers had the idea that an advanced application of the Hot Cycle system would be to spin up three-bladed “Y-Wings,” which could, once the vehicle was airborne and moving forward at a good clip, stop their rotation and be fixed in place as wings. This would drastically reduce drag and increase high-speed efficiency. So they drew up a series of “Y-Wing” vehicles… one of which is currently being auctioned on eBay, seen above. Numerous variations on the concept were designed, with varying ratios of “rotor size” to “hub size,” but all were meant to be high-speed aircraft that could take off and land vertically in the manner of a helicopter. Unfortunately, the XV-9 itself, with otherwise normal helicopter rotors, was a fuel hog, as well as loud. The Y-Wing in hover would have burned through fuel like it was throwing it overboard.

Airplane Lockheed Prototype Concept Desk Display Model

 We offer for auction a rare one off prototype model made by Lockheed from around the late 1950’s or early 1960’s.  This model is made from painted wood, it has a 22″ wingspan & is approx. 16″ long.  The propeller nose cones are aluminum & it has a wooden base with a slightly rusted steel support stem. There is a bronze plaque on the base that reads ” GL 136 B-1 Assault Transport Lockheed Aircraft Corp. Georgia Division Marietta Georgia” I think this was a proposal & never built, I cannot find any information about this aircraft.  The model comes in it’s original wooden carrying case.  The model when we found it was dirty, it also had some surface paint cracks were the tip tanks were mounted to the wings & some other areas.  The markings which seemed to be hand painted were smudged in a couple of spots & a number of the prop blades were detached. We gave this model to a master model maker that made similar model for the airlines & the military.  He cleaned it up & touched up the areas needing work. This was not a major job & it is almost impossible to see any restoration. This is a beautiful professional design model & one of a kind model.  The wooden carrying case measures approx. 28″ x 20″ x 12″ & is quite heavy.
