Halbeegyada ugu muhiimsan ee GE 7FDL Engine
Taxanaha GE 7FDL waa mishiin naafto ah oo afar-stroke ah oo dhexdhexaad ah oo uu soo saaray General Electric (GE). Waxa ugu horayn loogu talagalay jiidashada socodka tareenada, iyo sidoo kale lagu dabaqi karo nidaamyada tamarta badda iyo unugyada tamarta taagan. Hoos waxaa ku yaal xudduudaha farsamada ee asaasiga ah iyo qeexitaan faahfaahsan oo ku saabsan moodooyinka leh tirooyinka dhululubada kala duwan.
