AI Technical Summary

Technical Problem

The existing flap design of the NASA MS(1)-0317 airfoil has insufficient aerodynamic lift enhancement capability and a complex deployment mechanism with a large weight, making it difficult to meet the comprehensive performance requirements of general aviation aircraft.

Method used

A fixed-hinge flap structure for the NASA MS(1)-0317 airfoil was designed. The flap relative chord length is 29%, the fixed hinge relative sag is 15%, the flap leading edge relative radius is 6%, the flap relative thickness is 22%, the flap cabin horizontal length in the airfoil chord direction is 12%, the maximum designed flap deflection is 25°, the flap slot width is 1.4% of the airfoil chord length, and the slot overlap is 4.5% of the airfoil chord length. This design simplifies the flap deployment mechanism and improves aerodynamic lift enhancement.

Benefits of technology

Without increasing weight and complexity, the aerodynamic lift capability of the flaps is improved, meeting the lift requirements of general aviation aircraft during takeoff and landing, while reducing production and maintenance costs.
