1. A control apparatus for angling guide vanes of a torque converter, the control apparatus comprising:

  • a modeling unit configured to receive current condition data, to determine a current input power supplied by a starting motor from the current condition data and to output a result of the determination as a control signal; and

    a controller, which is coupled to the modeling unit and thereby receptive of the control signal,the controller being configured to execute a comparison of the current input power with a rating of the starting motor and to angle the guide vanes of the torque converter at an angle in accordance with a result of the comparison, wherein the current condition data comprise at least one of;

    a current rotational speed of an input shaft to which the starting motor and the torque converter are coupled;

    a current guide vane angle of the guide vanes of the torque converter; and

    a current rotational speed of an output shaft to which the torque converter and a compressor of a gas turbine engine are coupled,wherein the torque converter and the starting motor form a first pair and an additional starting motor and an additional torque converter form a second pair to apply torque to the output shaft, the control apparatus controlling respective operations of the first and second pairs.
