HOW TO COOL YOUR WANKEL BOOK

This 100 page book can be used as a guide when designing a liquid cooled Wankel rotary engine installation in an experimental aircraft. Information from the Aircraft Rotary Engine Internet Newsletter and a compilation of the published information from the established international experts in the field over the last seventy years. Includes a bibliography. The information applies to any liquid cooled aircraft engine. Printed on heavy weight gloss paper with many color illustrations and pictures
(Sizes 8-3/8 x 10-1/2 x 1/2).
