摘要： A gas turbine engine (10) having a longitudinal centerline axis (12) therethrough, including: a fan section (20) at a forward end of the gas turbine engine (10) including at least a first fan blade row connected to a first drive shaft (32); a booster compressor (28) positioned downstream of the fan section (20), the booster compressor (28) including a first compressor blade row and a second compressor blade row connected to a second drive shaft (33) and interdigitated with the first compressor blade row; and, a pulse detonation system (46) for powering the first and second drive shafts (32, 33). The pulse detonation system (46) powers only the second drive shaft (33) during a first designated condition of the gas turbine engine (10) and both the first drive shaft (32) and the second drive shaft (33) during a second designated condition of the gas turbine engine (10). The first and second drive shafts (32, 33) are powered independently of each other by the pulse detonation system (46).

摘要： A method (100) for reducing loads of a wind turbine (10) includes determining an angular pitch speed parameter of the rotor blade (22) of the wind turbine (10). The method (100) also includes determining an operational state of the wind turbine (10). Further, the method (100) includes comparing the angular pitch speed parameter to a predetermined parameter threshold during turbine shutdown and/or a commanded pitch event. If the operational state corresponds to a predetermined operational state, the method (100) includes yawing a nacelle (16) of the wind turbine (10) away from an incoming wind direction when the angular pitch speed parameter is below the predetermined parameter threshold during the turbine shutdown and/or the commanded pitch event.
