Liquid fuel from a rotary fluid trap is atomized by a sharp edge on an inside surface of an aft cavity of a bladed rotor of a gas turbine engine and directed into each of a plurality of associated hollow blades through corresponding blade inlet ducts that are in fluid communication with corresponding aft hollow interior portions of each blade. A radially-extending central rib within each blade partitions the hollow interior thereof into aft and forward hollow interior portions that are in fluid communication through an associated opening in the central rib and through a radially-extending gap between the central rib and the interior surface of the blade. A blade outlet duct provides for fluid communication between the forward hollow interior portion and a forward cavity of the bladed rotor, and a rotor outlet duct provides for discharging the fuel from a radially-inboard portion of the forward cavity.

Fuel-cooled bladed rotor of a gas turbine engine

Fuel () is supplied to a rotatable portion () of a gas turbine engine () comprising a rotor () and at least one blade () operatively coupled thereto, so as to provide for cooling at least one of the rotor () or the at least one blade () by transforming the fuel () to a vapor or gaseous state. The fuel () is discharged in a vapor or gaseous state from the rotatable portion () directly into a combustion chamber () of the gas turbine engine ().

Gas turbine engine cooling system and method

A multi-spool turbofan engine has a plurality of circumferentially spaced poppet valves with diverters secured thereto for precisely controlling bleed of combustion gas aft of the high pressure turbine whereby the high pressure spool operates at high idle RPM so as to power accessories and the low pressure spool operates at low RPM so as to minimize noise and fuel consumption.
