Fixed Transition Experimental Study on Airfoil Aerodynamic Characteristics of Kinds of Damaged Carborundum Strip

Abstract:

For the sake of improve the veracity and the reliability of the simulating the configuration of the bound layer above of the aircraft by manual fixed transition, discussing the influence of the dynamic coefficient and pressure coefficient of different types of the carborundum strip to enhance the efficiency of the experiment which of 3mm width from the leading edge at the location of 7% chord. At subsonic condition of Mach number is 0.5, The characteristic of the lift coefficient keeps insensitive of three breakage, and the drag coefficient shows the influence coming forth after attack angle greater than 6 degree, and the infection less as the breakage longer instance of the symmetry. When Mach number is 0.75, lift coefficient and drag coefficient shows the influence coming forth after attack angle is equal or greater than 6 degree, and the infection less as the breakage be longer instance of the symmetry.
