METHOD OF FUEL SUPPLY TO GAS TURBINE ENGINE AT ITS STARTING AFTER LONG PERIOD OF STANDING AT LOW TEMPERATURES AND FUEL SYSTEM OF GAS TURBINE ENGINE Russian patent published in 2001 - IPC

FIELD: aircraft industry; gas turbine engine fuel systems. SUBSTANCE: according to proposed method ice formation fuel is separated from fuel delivered into fuel filter before heating. Ice is melted and water, thus formed is mixed with heated fuel. Fuel system of gas turbine engine has fuel-and-oil heat exchanger and fuel filter installed in tandem in fuel main line. Ice separator and collector furnished with heater are installed in fuel main line before fuel-and-oil heat exchanger. Outlet of collector is connected with fuel main line between fuel-and-oil heat exchanger and fuel filter. EFFECT: improved reliability of take-off after long standing at below-zero temperature by freeing fuel from ice. 4 cl, 2 dwg
