Studies of the screening surface proximity on integral aerodynamic characteristics of rectangular high-lift wings of different aspect ratio

Resumo

In this paper, we examine the aerodynamic characteristics of models of rectangular wings with double-slotted flap at conditions of ground proximity near the screen. We determined a number of parameters that made it possible to represent the aerodynamic characteristics of high-lift systems in generalized and parametric form. Also determined is the dependence of the effective aspect ratio increment on the relative height.
