SYSTEM AND METHOD FOR EFFICIENTLY DETERMINING A PHASE SHIFT IN A PROPULSION SYSTEM
This abstract first appeared for US patent application 18335340 titled 'SYSTEM AND METHOD FOR EFFICIENTLY DETERMINING A PHASE SHIFT IN A PROPULSION SYSTEM
Original Abstract Submitted
A propulsion system includes at least two propulsors. The at least two propulsors each comprising a fan having a plurality of fan blades. A controller includes memory and one or more processors. The memory stores instructions that when executed by the one or more processors cause the system to perform the following: determine a pairwise phase difference between one propulsor of the at least two propulsors and another propulsor of the at least two propulsors; generate a reference phase angle; determine a target phase shift for each propulsor of the at least two propulsors; and adjust a speed of each propulsor of the at least two propulsors based on the target phase shift until the pairwise phase difference is equal to the reference phase angle.
