Noise Test and Simulation of Military Aircraft

Based on the demand for noise control and protection,a study on the noise diffuse and intensity of military aircraft is carried out.A boundary element model is established,making use of the ANSYS.In the noise simulation SYSNOISE is applied to get estimable simulation results of aircraft noise close to ground.A minitype wireless noise measure system is designed to act as an automonitor,which has been proved to be a practical device.
