ICE TOLERANT GAS TURBINE FUEL SYSTEMS

摘要

A fuel system for a gas turbine engine includes a fuel conditioner. The fuel conditioner has an ice debris separator, a fuel pump, a heat exchanger, and an air oil cooler. The ice debris separator has a fuel inlet and a fuel outlet. The fuel pump connects to the fuel outlet of the ice and debris separator for receiving a fuel flow, pressurizing the fuel flow, and providing the pressurized fuel flow to an outlet of the fuel pump. The heat exchanger is connected to receive pressurized fuel from the fuel pump outlet and has an oil inlet for receiving heated oil, an oil outlet for discharging cooled oil, and a fuel outlet for discharging heated fuel. The air oil cooler is connected to the heat exchanger oil outlet and has an air cooled body configured for further cooling oil from the heat exchanger using an air flow.
