text: To get thrust, an aircraft engine is either a shaft engine – piston engine or turboprop, with its efficiency inversely proportional to its brake-specific fuel consumption – coupled with a propeller having its own propulsive efficiency; or a jet engine with its efficiency given by its airspeed divided by the thrust-specific fuel consumption and the specific energy of the fuel.[need quotation to verify]
