BGT (ATPL Systems) verified to pass

BGT (ATPL Systems)What is Thrust output a product of? - Mass airflow - Acceleration What is EPR? Engine pressure ratio Exhaust gas (Jet pipe) : Inlet air pressure Brainpower Read More Previous Play Next Rewind 10 seconds Move forward 10 seconds Unmute 0:02 / 0:15 Full screen What is the most important indication of thrust output in a turbojet? EPR What effect does a blocked EPR gauge have? Overread (actual power output is lower) How does high by pass engine produce thrust? By giving a relatively small acceleration to a large mass of air? How is by pass ratio measured? By-pass air : Core air What are the advantages of a free power turbine? - Lower starting torque - lower variable prop speed - High torque at low rpm What does the reduction drive/gearbox in a turboprop do? converts very high RPM/low torque to manageable low RPM/high torque for use by the prop. How much thrust is produced by exhaust from a turboprop engine? Around 10%
