Tapered wing definition The root bending moment (caused by the lift) decreases accordingly. 1 The General Trapezoidal Wing Figure 2. During the design phase, the basic dimensions of the wing (span and chord at root and tip) are sometimes defined by wing area, taper ratio, and aspect ratio as governing variables. Wing design is one of the most important tasks for a designer to overcome during an aircraft design process. 8a . Trapezoidal : a tapered wing with straight leading and trailing edges: may be unswept or swept. The chord legth decreases towards the tip. Find examples are given. Hence, its efects on wing’s aerodynamic parameters are also (If a wing has a rectangular planform, rather than tapered or swept, then the chord is simply the width of the wing measured in the direction of airflow. Technical Aspects For a conventional trapezoidal wing the spanwise location of the mean aerodynamic chord has a simple equation and it can even be The previous discussions on wings have dealt only with airfoil section properties and two dimensional airflow.
