Abstract: The present invention relates to a method of noise reduction including the steps of filtering reference signals and representing noise by an adaptive filter comprising adaptive filter coefficients to obtain actuator driving signals, outputting the actuator driving signals by loudspeakers to obtain loudspeaker signals. The method further includes detecting the loudspeaker signals by microphones and filtering the reference signals by estimated transfer functions representing the transfer of the loudspeaker signals output by the loudspeakers to the microphones to obtain filtered reference signals. The method further includes updating the filter coefficients of the adaptive filter based on the filtered reference signals and based on the previously updated filter coefficients of the adaptive filter multiplied by leakage factors.

Abstract: A wheel drive system for an aircraft that features at least one electric motor and at least one fuel cell as energy source for the electric motor, wherein the electric motor is coupleable to at least one wheel of at least one landing gear of the aircraft. The wheel drive system reduces the fuel consumption and lowers the emission of CO2 and pollutants—primarily carbon monoxide and unburned hydrocarbons. Persons, vehicles and other aircraft furthermore are not endangered by a jet blast while the aircraft is taxiing because the main engines do not have to be started until the take-off and landing strip is reached. The operation of the wheel drive system furthermore leads to a reduced noise pollution.
