Abstract
This invention relates to the exchange, removal or addition, as applicable, of media and/or power between the individual shafts of an engine, between individual engines and between the engines and the aircraft. Thus, the present invention provides for additional degrees of freedom 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.
Claims37
A method for the control of at least one engine of an aircraft, wherein an amount of at least one of energy, fluid and other media that is at least one of supplied to and taken from the engine, is altered to alter the speed of at least one shaft of the engine.
A method for the control of at least one engine of an aircraft, wherein an amount of at least one of energy, fluid and other media that is at least one of supplied to and taken from the engine, is altered to alter an excitation frequency of the engine.
A method for the control of at least one engine of an aircraft having at least two engines, wherein an amount of at least one of energy, fluid and other media that is at least one of supplied to and taken from the engine, is altered to alter thrust from that engine to alter trimming of a rudder of the aircraft.
