Assignee: RTX CORPORATION
Field: Engines, pumps, turbines (Mechanical engineering)
Classification: CPC F  B | IPC B  F

Claim 7:
8. A method for treating a fuel system of a turbine engine, the method comprising:
connecting a treatment system to the turbine engine, the connecting comprising fluidly coupling the treatment system with a fuel system interface, wherein the fuel system includes an injector, the fuel system interface and a flow regulator, and the flow regulator is fluidly coupled between the injector and the fuel system interface; and
drawing preservation fluid out of the fuel system using the treatment system, wherein the preservation fluid is drawn out from the fuel system at the injector through the flow regulator,
wherein the treatment system includes
a control system configured to signal the flow regulator to open;
a fluid system including a fluid system interface and a first pump fluidly coupled with the fluid system interface, the fluid system interface configured to fluidly couple with the fuel system interface, and the first pump configured to draw the preservation fluid out from the fuel system; and
the fluid system further including a second pump configured to prime the fuel system with fuel after the preservation fluid is drawn out of the fuel system by the first pump.
