الملخص EN

In this paper, a comprehensive optimization approach is presented to analyze the aerodynamic, acoustic, and stealth characteristics of helicopter rotor blades in hover flight based on the genetic algorithm (GA).

The aerodynamic characteristics are simulated by the blade element momentum theory.

And the acoustics are computed by the Farassat theory.

The stealth performances are calculated through the combination of physical optics (PO) and equivalent currents (MEC).

Furthermore, an advanced geometry representation algorithm which applies the class function/shape function transformation (CST) is introduced to generate the airfoil coordinates.

This method is utilized to discuss the airfoil shape in terms of server design variables.

The aerodynamic, acoustic, and stealth integrated design aims to achieve the minimum radar cross section (RCS) under the constraint of aerodynamic and acoustic requirement through the adjustment of airfoil shape design variables.

Two types of rotor are used to illustrate the optimization method.

The results obtained in this work show that the proposed technique is effective and acceptable.
