The design of a light weight, medium performance powered glider, with particular reference to various international performance requirements, is presented. The aircraft was designed as an efficient two place touring aircraft with the characteristics of a powered glider, which could be fabricated by amateur builders from commercially produced kits. This work was undertaken initially as a group project for the Engineering 88-510 class, winter term 1971/72, with the class divided into various design groups. This thesis represents the basic design work done during this period by the design groups as well as the follow on analysis done by the author to combine the various design studies into a comprehensive and complete performance analysis of the BW-1 powered glider.
