METHOD AND SYSTEM FOR NOISE PREDICTION OF A TIP JET ROTOR

摘要

Disclosed are a method and a system for interpreting noises of a tip jet rotor. The method for interpreting noises of a tip jet rotor includes the following steps of: interpreting blade noises generated by a blade of the tip jet rotor based on a blade shape and a flight condition of the tip jet rotor; interpreting jet noises generated by a nozzle of the tip jet rotor based on a shape of the nozzle formed on the end of the blade and a jet condition; and determining the entire noises of the tip jet rotor by using the interpreted blade noises and the jet noises.
