Design of the high-lift device, one of the key technologies of civil aircraft, enhances take-off and landing performance by increasing the circumflexion and effective area of the airfoil section while at the same time enlarging the stalling-angle in the process. As the level of the aerodynamic design of modern aircrafts improves, forms of the high-lift device are increasingly simplified with leading-edge slat and single-slot Fowler Flap used widely in civil aircraft. While ensuring aerodynamic efficiency, they also excel in reliability and overall performance with simple structures, light weight and low noise. Under the restraint of multi-targets, a high-lift device sets several units with each one measuring up to qualified aerodynamic design. In this article, optimization analysis of parameter of trailing-edge flap recession on some civil aircraft is made with conclusions verified by results of wind-tunnel tests.
