Abstract

This thesis report explores the effect of the Clark-Y wing geometry on lift and drag to use as a reference during aircraft design stage. The different characteristics investigated are fixed slot span, taper ratio, washout, and sweep angle. Plain wings, half slotted wings, and fully slotted wings were built in CATIA with an aspect ratio of 6 and different taper ratio, washout, and sweep angles. Using the CATIA models to generate the 3-D grids in Pointwise. All the simulations were tested in Ansys-Fluent under sea-level conditions with a Reynold number of 609000. The relationships between the aerodynamic characteristics and the geometric parameters are discussed, which can be used during the aircraft design stage as a reference. The optimum choice for the wing geometry is obtained for the highest maximum lift and high angle of attack for maximum lift. In the end, there is a proposal for future work opportunities to improve the conclusion.
