“The quest for a small UAS engine that burns diesel or JP-5 fuel rather than aviation or automotive gasoline has been underway since the 1980s. The latest bump in this long road was the acquisition in July of Thielert, manufacturer of the diesel engine for the U.S. Army's MQ-1C Gray Eagle UAS, by China's Avic.

This has forced the Army and General Atomics to adopt Lycoming's DEL-120 diesel—an engine that Lycoming did not show at Auvsi, instead bringing its smaller, 63-hp EL-060 (a spark-ignition multifuel two-stroke). One question is when the new DEL-120 will be able to attain the time between overhauls needed for UAS use. The Thielert engine became notorious in the personal-aircraft market for frequent and expensive inspections and overhauls.”
