The present paper focuses on the mechanism investigation and parametric analysis of the nacelle strake mounted on the high-lift configuration of civil transport aircraft. Numerical simulation is carried out for this research. Results show that appropriate design of strake could greatly improve the aerodynamics performance of the high-lift configuration. The maximum lift coefficient can be increased by least 0.3 and the angle of attack can be increased by 3°. Through parametric analysis of the nacelle strake, it’s found that the strength of the vortex generated by the strake is a key factor of its stall delay effect. In the research, influences of the installation parameters of the inboard strake are that through affecting the strake’s local angle of attack, the axial location of the strake controls the strength of the vortex; the circumferential angle affects the strake’s incoming flow speed, and then controls the strength of strake’s wake; the area of the strake nearly has no effect on lift coefficient of high-lift configuration, it mainly affects the stall behaviors of the high-lift configuration.
