Embodiment Construction
[0053] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0054] The present invention proposes an aeroengine noise prediction method based on multiple regression, such as figure 1 shown, including the following steps:
[0055] Step 1: Obtain the time-domain signal of the internal noise of the aero-engine and the parameter matrix X of the working state of the aero-engine n×k , n is the number of aero-engine working states, and k is the number of selected aero-engine working state parameters.
[0056] In this embodiment, the working state parameters of the aeroengine include: the total temperature T of the inlet section * , the total pressure of the inlet section P * , air flow G B , residual air coefficient α, that is, the number of aeroengine operating state parameters n=4.
[0057] Step 2: Preprocess the time-domain signal of the internal noise of the aero-engine to obtain the 1 / 3 octave s...
