Abstract

The paper presents an analytical method in the classical problem of flow around a thin rectangular plate with and without winglets. There is described the method for calculating inductive reactance of the thin plate. The method for calculating the suction force, to calculate the inductive reactance of the plate with winglets is considered. There is also described a discretization of equations, to calculate inductive reactance. Then we demonstrate a comparison of the aerodynamic quality for plates with and without winglets. After that, we give some conclusions about the influence of winglets on the aerodynamic quality of the thin plate with winglets, taking into account the suction force.

Keywords:

aerodynamics, thin rectangular plate, winglets, lifting force, aerodynamic quality
