US Patent 11105268 Fuel polishing system for test cells

Systems and methods for providing an automatic fuel polishing and on-demand fuel delivery for one or more gas turbine engine test cells are provided. The system can have a polishing loop that can continuously polish fuel. The polishing loop can have at least a fuel storage tank, a pump assembly, a filtration system, and a flow meter. The system can also have fuel delivery path coupled to the polishing loop at a three way junction. The three way junction can enable the continuous polishing loop when no test cells are operating. Upon initiation of one or more test cells, the delivery path can draw fuel from the polishing loop via the three way junction for use by the test cells. The flow meter can measure a corresponding drop in flow within the polishing loop and cause an increase in flow by the pump assembly.
