GAS TURBINE FUELS
106. Fuels for aircraft gas turbine engines must
conform to strict requirements to give optimum
engine performance, economy, safety and overhaul
life. Fuels are classed under two headings, kerosine-
type fuel and wide-cut gasoline-type fuel.

for the governor weights, resulting in fuel being
metered on mass flow rather than volume flow.
105. Changes to a lower grade of fuel can lead to
production of carbon, giving a greater flame
luminosity and temperature, leading to higher
combustor metal temperatures and reduced
combustor and turbine life. Fig. 10-20 Fuel flow distributor.
