Weight Engineering - Procedures %X Glasswind brings the next step of modern technology to the homebuilt aircraft community at modest construction and operational cost - truly advanced technology in the grasp of anyone. Gemini is a two place, two engine general purpose airplane constructed of kevlar, kevlar/foam sandwich, and reinforcement with graphite fiber where design sense allows. These materials in combination with selection of two engines, careful configuration to mild and forgiving handling qualities, design detail development, and load sizing to utility and aerobatic factors are all indicative of the goal of paramount safety. Low operating cost is achieved by minimum weight design emphasis and selection of an engine which provides high thrust-to-weight at reasonable fuel use rates. The cost of ownership is reduced by incorporating a removable wing which features removal or installation in a few minutes by one person and which permits storage of the airplane at home rather than a more expensive space at an airfield. In this paper, the presentation of the configuration is supported by an in-depth description of the preliminary design evolution and the design details which were the genesis of Gemini. Details of design trade studies that produced the major minimum weight approaches featured in the structure are shown. Careful attention was given to advanced material application that is easy for the hobby builder to form into airframe structure with common tools. %B 42nd Annual Conference, Anaheim, California, May 23-25 %I Society of Allied Weight Engineers, Inc. %C Anaheim, California %P 17 %8 5/23/83 %G eng %U https://www.sawe.org/papers/1528/buy %9 17.
