Latest Patents
One of Purcell's key inventions is a method to control starter/generator cooling fuel flow during engine starting. This patent provides a relatively simple way to automatically turn on and off the fuel to a starter/generator cooling system during engine start. The invention takes advantage of a fuel pressure rise provided by an engine fuel boost pump during the transition from engine start to idle conditions. This pressure rise is utilized to stroke a shutoff valve in a fuel return to tank valve (FRTTV), effectively shutting off the starter generator cooling fuel flow. Notably, this shutoff occurs automatically without requiring external input from an engine controller. Additionally, a check valve is included to prevent backflow through the FRTTV in the event of an engine start with no aircraft pumps running. Purcell holds 1 patent for this innovative solution.
