The development of a lightweight, compact, simple and reliable Heavy Fuel reciprocating engine for aerospace applications has been attempted by numerous companies.  Most of these engines are derivatives of automotive engines. DeltaHawk Engines, Inc. of Racine, Wisconsin has spent well over a decade developing a purpose-built aviation engine targeted both for General Aviation and UAS applications.  The goals of this project have been to produce an engine that burns heavy fuels with high fuel efficiency, manned-aircraft reliability and very low maintenance.  With sufficient funding now in-hand, the engine is nearing completion, with FAA Certification and commencement of production targeted in 2019.

Aviation engines present a challenging set of problems for engineers, many of which are unique to aviation. The engine requirements include race-engine like performance, combined with very low weight, compact size, and extraordinary reliability and durability.  The added challenge is that these engines must meet extremely high regulatory standards and oversight from aviation authorities. Light General Aviation aircraft have historically utilized air-cooled, spark-ignition engines, literally derivatives of World War II technology.  These engines burn specialized aviation gasoline, which is under environmental pressure.  

DeltaHawk has developed a Jet-Fuel powered General Aviation engine that brings the advantages of diesel technology to aviation.

This presentation will give an overview of the history of aviation diesels, the market drivers, and a look at the DeltaHawk engine architecture.
