Abstract
Based on unsteady Navier-Stokes equations, dynamic response in vertical gust flow perturbation is investigated for the aircraft. The grid velocity method was introduced to simulate the gust influence in time domain. First, after applying this method to simulate typical NACA0006 airfoil gust response to a step change in the angle of attack, it is shown that the calculated lift responses of the airfoil agree well with calculated value in reference. This example verified the accuracy of the time domain simulation method. Furthermore, gust responses for the One-Minus-Cosine gust profile and Sin gust profile are analyzed for the flying wing aircraft. It is found that the response of airfoil aerodynamic was obvious during traveling the gust. The research of variation of aerodynamic force under the action of gust response is important to the gust load alleviation and aircraft design.
