Design Development and CFD Simulation of a Variable Twist Wing

Sources
Abstract
: Wing twist is an  aerodynamic feature added to  aircraft wings to adjust lift distribution along the wing. Often, the purpose of lift redistribution is to ensure that load distribution is uniform from wing tip to root, it ensures that the effective  angle of attack is always lower at the wing tip than at the root, meaning the root will stall before the tip. This is desirable because the aircraft's  flight control surfaces are often located at the wingtip, and the variable stall characteristics of a twisted wing alert the pilot to the advancing stall while still allowing the control surfaces to remain effective, meaning the pilot can usually prevent the aircraft from stalling fully before control is completely lost . Twist that decreases the local chord's incidence from root to tip is sometimes referred to as  washout . In this project the design is done in GAMBIT software, and CFD simulation of twisted wing is done in fluent software, the designed model is tested in software at different twist angles, and at different angles of attack to find the aerodynamic properties like C D , C L , and pressure.
