초록

Systems and methods for changing a speed ratio between a compressor boost stage (12) and at least one power turbine (16) of a gas turbine engine (10) are described. Such a system may comprise a coupling device (20) configured to selectively transmit energy from the at least one power turbine (16) to the boost stage (12) according to at least a first speed ratio and a second speed ratio. The system may also comprise an auxiliary power device (22, 26) configured to cause a rotational speed of the boost stage (12) to change from a first speed corresponding ...

1. A method for changing a rotational speed of a compressor boost stage driven by at least one power turbine of a gas turbine engine relative to a speed of the at least one power turbine, the method comprising: driving the boost stage at a first rotational speed corresponding to a first speed ratio between the boost stage and the at least one power turbine via coupling between the boost stage and the at least one power turbine;decoupling the boost stage from the at least one power turbine;changing the rotational speed of the boost stage from the first ro...
