ENVIRONMENTAL FACTORS AFFECTING THE INSTALLATION AND OPERATION OF GAS TURBINE ENGINES IN AGRICULTURAL AIRCRAFT

The environmental factors influencing the design of gas turbine engines for agricultural (ag-) aircraft are discussed under two categories: operational and atmospheric. Operational criteria relate to engine loads, propeller whirl flutter, engine low cycle fatigue, and fuels (diesel and gasoline as alternative to jet fuel). Atmospheric criteria encompass intake filtration (barrier and vortex generator filters), cockpit environmental control, fuel control protection, material coatings, and engine washing. Engine design itself is discussed in terms of: mount structure configuration, intake design envelope, cowling shape, and position of various accessories and options (oil coolers, exhaust stubs, propeller systems). Operational data are presented for the gas turbine-powered ag-aircraft in terms of performance and mechanical integrity. Future developments of the engine and associated systems are indicated.
