The Variable Cycle Diesel as an Aircraft Engine, Part 1 891065

A brief summary of previous significant aircraft diesel engine development and application is presented along with a comparison with the then contemporary state-of-the-art aircraft gasoline engine. Performance results for an Advanced Variable Cycle Diesel (AVCD) engine obtained from a computer simulator code are presented and comparisons made with an identical fixed cycle engine. Some operational benefits of an AVCD engine are discussed along with an alternate method of controlling the engine's pre-compression turbocompressor. Finally, the altitude capability of an AVCD engine is shown and a description of a 750 SHP AVCD aircraft engine suitable for use on a medium size subsonic business transport plane is presented along with its projected performance.
