The Aristocraft II was a six-place homebuilt aircraft designed by Terrence O'Neill.[2]
Design and development
The Aristocraft II was a redesigned aircraft built off the prototype airframe of the WACO Aristocraft. The Franklin-powered Aristocraft pusher was rebuilt using the wings and most of the internal structure of the original. The layout was drastically changed from a twin-tailed, mid-engined, pusher to a conventional tractor arrangement. The intent was to develop a homebuilt aircraft from the design with the flexibility to carry six passengers, or fewer people with extended range.[3][4] An effort was made to certify the design, under the name Model W Winner but money ran out before completion, with only two orders.
The Aristocraft II was a strut-braced, high-wing, tricycle gear, six-passenger aircraft designed for Franklin or Lycoming 200 hp (149 kW) engines.[5] The fuselage was made of welded steel tubing with aluminum skin. The cowling was split vertically, and could hinge open for maintenance.[6]
Variants
The standard engine was a six-cylinder Lycoming, however plans were drawn for a 245 hp (183 kW) Jacobs L-4MB radial engine installation and also for a Continental R-670 radial installation. This specified that the engine would be mounted closer to the firewall and also incorporated conventional landing gear, a 93 in (236 cm) propeller and the outward appearance of "Mr. Muligan", this evolved into the O'Neill Magnum.[7]
