    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 gas turbine engine (44) having a longitudinal centerline axis (12) therethrough, including: a fan section (16) at a forward end of the gas turbine engine (44) including at least a first fan blade row connected to a first drive shaft (40); a booster compressor (20) positioned downstream of and in at least partial flow communication with the fan section (16) including a plurality of stages, each stage including a stationary compressor blade row and a rotating compressor blade row connected to a drive shaft (40/51) and interdigitated with the stationary compressor blade row; a core system (45) positioned downstream of the booster compressor (20), where the core system (45) further includes an intermediate compressor (47) positioned downstream of and in flow communication with the booster compressor (20), the intermediate compressor (47) being connected to a second drive shaft (51), and a combustion system (46) for producing pulses of gas having increased pressure and temperature from a fluid flow (52) provided to an inlet (54) thereof so as to produce a working fluid (48) at an outlet (50); and, a low pressure turbine (36) positioned downstream of and in flow communication with the core system (45), the low pressure turbine (36) being utilized to power the first drive shaft (40). The core system (46) may also include an intermediate turbine (49) positioned downstream of the combustion system (46) in flow communication with the working fluid (48), where the intermediate turbine (49) is utilized to power the second drive shaft (51). A first source (64) of compressed air (52) having a predetermined pressure is provided to the combustion system inlet (50) and a second source (66) of compressed air (65) having a pressure greater than the first source (64) of compressed air (52) is provided to cool the combustion system (46).

    摘要: A pulse detonation system (40) for a gas turbine engine (10) having a longitudinal centerline axis (12) extending therethrough includes a rotatable cylindrical member (42) having a forward surface (44), an aft surface (46), and an outer circumferential surface (48), where a plurality of spaced detonation passages (52) are disposed therethrough. Each detonation passage (52) includes at least a portion having a longitudinal axis extending therethrough oriented at a circumferential angle to the longitudinal centerline axis (12). The pulse detonation system (40) further includes a shaft (36) rotatably connected to the cylindrical member (42) and a stator (62) configured in spaced arrangement with the forward surface (44) of the cylindrical member (42) and a portion of the shaft (36). The stator (62) has at least one group of ports formed therein alignable with the detonation passages (52) as the cylindrical member (42) rotates. In this way, detonation cycles are performed in the detonation passages (52) so that combustion gases exit the aft surface (46) of the cylindrical member (42) to create a torque which causes the cylindrical member (42) to rotate.
