METHOD AND SYSTEM FOR CALCULATING AERODYNAMIC LOAD OF UPPER WING OF DUAL FOLDABLE WING

摘要

According to an embodiment of the present invention, a method for calculating an aerodynamic load of an upper wing of a dual foldable wing including a lower wing connected to a lower hinge radially protruding from a fuselage to be rotatably installed and an upper wing rotatably installed on an upper hinge attached to an upper end of the lower wing comprises: a position condition determining step of calculating (i) a characteristic length (L_2) from a center of the fuselage to the upper hinge and (ii) a characteristic angle () formed by an extension line connecting the center of the fuselage and the upper hinge and an extension line of the lower wing based on a distance (L_1) to the lower hinge from the center of the fuselage, a first folding angle (_1), and a length (L_3) of the lower wing; and a single equivalent wing model generating step of generating a mathematical equivalent wing model having an equivalent hinge separated from a center of a virtual fuselage having the same standard and mass as the fuselage by the distance (L_2), and a single equivalent wing which has the same standard and mass as the upper wing and is installed to be rotated with respect to the equivalent hinge.;COPYRIGHT KIPO 2019
