Abstract

A system and a method of noise mitigation for hybrid and electric aircraft are disclosed, the aircraft having a controllable pitch propeller or rotor(s) with a plurality of blades. The propeller or rotor(s) are driven by a drive system to provide thrust for the aircraft, and the blades of the propeller or rotor(s) are further movable about pivot axis to vary a pitch thereof. A controller on- boardthe aircraft is operable to cause rotation or movement of the blades of the propeller or rotor(s) about their pivot axis to alter and / or focus at least one aspect of the propeller generated noise toreduce or mitigate such noise while maintaining a substantially constant thrust, altitude, and / or air speed of the aircraft.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of previously co-pending U.S. Provisional Patent Application No. 62 / 504,169, filed May 10, 2017. [0003] Incorporation by reference [0004] The specification and drawings of U.S. Provisional Patent Application No. 62 / 504,169, filed May 10, 2017, are expressly incorporated herein by reference as if set forth in their entirety. technical field [0005] The present disclosure relates to hybrid and electric aircraft, and in particular, to systems and methods for reducing noise from the operation of such aircraft. Background technique [0006] Hybrid and electric aircraft propulsion technologies can reduce carbon emissions, fossil fuel use, operating costs, and the noise footprint impact of modern aircraft. However, aircraft noise is not a trivial problem and is expected to become a major design issue for hybrid and electric aircraft. For example, when the demands for propulsion and / ...
