The present invention relates to a method for optimally designing a paraglider to form an optimal shape of a slot, wherein the paraglider includes multiple compartments divided by partition walls and has a slot formed at a wingtip part to prevent vortex at a wingtip, wherein the slot is arranged in a compartment adjacent to a wingtip and composed of: a first duct having an air inlet which is located at the lower side of the compartment and which air is introduced through and an air outlet which is located at the upper side of the compartment and which high-pressure air is discharged through; and a second duct located at a rear side of the first duct in the compartment to have an air inlet which is located at the lower side of the compartment and which air is introduced through and an air outlet which is located at the upper side of the compartment and which high-pressure air is discharged through, wherein the first and the second duct have a curved shape with a cross-sectional area decreasing from the air inlet to the air outlet. The present invention provides a method for optimally designing a paraglider slot, which comprises a step of calculating wall shear stress by using the following formula while changing values of d1, d2, s1, and s2. |
