WebIn this video we consider a turbofan engine on a commercial aircraft. These engines are started through a set of switches in the cockpit. The start sequence of the engine, gets … Starting of a gas turbine engine requires rotation of the compressor to a speed that provides sufficient pressurised air to the combustion chambers. The starting system has to overcome inertia of the compressor and friction loads, the system remains in operation after combustion starts and is disengaged once the engine has reached self-idling speed. WebFor turboprops, the NG parameter is an indication of turbine health and the amount of energy present in the engine. Remember that NG is the gas generator speed. NG references the rotation speed of the compressor section of the engine. During starts and shutdowns, N G is a primary instrument to determine proper engine operation. ctrl symbols list
