Schultz Nucleon

TerryLeave a comment

The Nucleon designed by Art Schultz, which first flew in 1954, has a wing bult of Styrofoam around a spar and convered with a fiberglass shell. To save weight, struts were used with cuffs at both ends. It has full span flaps, with drooping ailerons, and a horizontal tail which folds up for trailing.

The structure was I-strut braced all-wood wings, steel-tube/ fabric wings and braced tail.

Schultz ABC / TG-16

TerryLeave a comment

The ABC, an Art Schultz development of the simpler, shorter span Midwest MU-1 designed three years earlier, won the 1937 Eaton design competition. The result was due largely to its design and ease of construction, while the much higher performing Ross-Stephens RS-1 Zanonia placed second due to complicated construction and emphasis on ground tow capability. The first all-metal Schweizer sailplane, the SGU-1-6, was third.

The structure was steel tube fuselage and tail, two-spar two-strut wood wing, all fabric coverd. The ABC was offered in plan form and a few were built prior to World War II. After the outbreak of war, one was used as the TG-16 at the USAAC glider training school in Mobile, Alabama.

Schülke Flügelfliegermodell

TerryLeave a comment

This machine with two four-blade propellers but no wings was the subject of a detailed article in Flugsport and patents in several countries. It was constructed by Ingenieur Julius Schülke of Jena, Germany, in 1909 together with his son Oberleutnant Schülke. Nothing is known of tests, but it looks very unlikely that they would have led anywhere.

Sclaves 1910 Biplane

TerryLeave a comment

This tractor French biplane, constructed of metal pipes and an abundance of wire bracing, powered by an acetylene motor was tested at Amberieu in 1910 by a man from Lyon named Sclaves. At least one photo shows a 50 hp Prini-Berthaud engine. The rectangular wings were braced entirely by one pair of outboard struts on each side and wires from double kingposts on top. The heavy forward box structure seemed made of pipes; the rear fuselage was uncovered. The two wheels were castering.
