The Aircraft Roll Aerodynamic Characteristics Numerical Simulation

Abstract

The roll control is fighter aerobatic training subjects, often. Usually includes the dive, roll and barrel roll and other operations. According to the roll maneuver characteristics, based on the finite element method to complete the analysis of the flow field of the wing. The finite element method to solve the basic idea is to divide the flow field which has be used in the discretization procedure were established equilibrium equation of each unit, in accordance with each element node displacement compatibility conditions and equilibrium conditions, the equilibrium equation of the whole system is established.
