摘 要:Optimizing flying objects’wing performance has attracted a significant attention in the last few *** this article,some of the main mechanisms for changing the geometry of the wing were investigated and a new mechanism is proposed to improve the aerodynamic performance of the airplane *** designs have been simulated and analyzed from both aerodynamic and control points of *** aerodynamic simulations using CFD methods,two airfoils of NACA series 6 with specifications 65-212 and 65-2012 were *** results indicated that both airfoils used have a better performance compared to others in a certain range of the angle of ***,a new mechanism is proposed to change the wing geometry to optimize its *** the proposed mechanism,the structures of airfoils and wings consist of two fixed and moving parts,which can change their geometry with the help of a control *** fixed part has a grooved track,and as the moving part moves in the direction of the grooves,the curvature of the upper and lower parts of the wing *** design control circuit includes an angle sensor,a micro controller,and a *** CFD results are entered into the micro controller as *** any moment,the micro controller receives the angle data from the angle sensor and by comparing them with the CFD data,and issuing a command to the servomotor,it situates the wing curvature in the optimal state at all *** built mechanism was tested at an attack angle of 0°and 25°.The results showed that the different parts of the mechanism work with very high precision and put the geometric shape of the wing in an optimal state in a completely intelligent *** should be noted that the average error in test for t/c and Xt/c was 15.3% and 9%,respectively.
