Abstract

The exchange, removal or addition, as applicable, of media and/or power is provided between the individual shafts of an engine, between individual engines and between the engines and the aircraft. Thus, additional degrees of freedom are provided, enabling engine parameters to be addressed in terms of a reduction or avoidance of negative resonances or beats. It also provides an ability to alter thrust from engines of a multi-engined aircraft to reduce rudder trim.
