Beschreibung
Zusammenfassung:	A fuel supply system (10) for a gas turbine engine includes a fuel tank (12), a pumping unit (18) downstream of the fuel tank (12) and configured to receive fuel from the fuel tank (12), and a sharing valve (24) downstream of the pumping unit (18) and configured to receive fuel from the cruise pump (36) of the pumping unit (18) during a first operating condition. The pumping unit (18) includes a boost pump (34), an actuation pump (38) downstream of the boost pump (34) and in fluid communication with at least one actuator of the gas turbine engine, and a cruise pump (36) downstream of the boost pump (34) and in fluid communication with nozzles of a gas generator of the gas turbine engine.
