AN EXAMINATION OF THREE SAILPLANE CONFIGURATIONS

Gary Weir

Abstract


The purpose of this paper is to examine different possible configurations for sailplane design. As an alternative to the conventional layout, a number of people have tried canard designs in the quest for improved safety and efficiency. A conventional sailplane frequently has a negative load on the tailplane, particularly at high speed. Probably the most famous canard sailplane design is the Solitaire. It appeared to have good performance in a straight line, but not in circling flight. It will be interesting to try and understand why this mightbe so. A third possible configuration is that of the three surface aircraft; that is one with both a canard surface at the front and a conventionalhorizontal tail at the back. To the author's knowledge no sailplane has yet been built with this configuration.
