Abstract
Exciting developments have occurred over the past two years in the technological status and production aspects of Stratified Charge Rotary Engines. A program is currently underway for the development, certification and production of a 400 HP aircraft engine in early 1990. The joint program is being conducted by John Deere’s Rotary Engine Division and AVCO Lycoming Williamsport Division. The engine will offer to the General Aviation community Jet-A fuel capability at substantial cost savings, improved altitude capability and lower fuel consumption over turbine power plants. Application to fixed wing and rotary wing aircraft are planned. Other stratified charge rotary engine development work in progress involves ground power units, airborne APU’s, shipboard gensets and vehicular engines, supported by Deere production capabilities and DOD interests. Technology enablement efforts by NASA, aimed at highly advanced output and efficiency are in progress leading toward revolutionary engine capability for aircraft and other applications.
