초록

A method for accelerating a gas turbine engine (10) with an air turbine starter (14) employs sensor data (48, 50) indicative of both starter speed and engine speed to enable speed-synchronized engagement of the starter output shaft (16) with an engine input shaft (18), thereby minimizing clutch damage and engine restart time.

청구항

A method for accelerating a gas turbine engine with an air turbine starter, wherein the starter has an output shaft that is selectively engageable in driving relation with an input shaft which is engaged with the engine, and wherein the starter is adapted to receive and be driven by pressurized air delivered to an inlet of the starter via a flow control valve, comprising the steps of: (a) sensing the rotational speed, “F1”, of the output shaft; (b) sensing the rotational speed, “F2”, of the input shaft; and (c) selectively responding to the sensed rotati...
