Study Notes
Elliptical Wing Planform
- Produces consistent lift across the entire wing span, maintaining the same effective angle of attack (AOA).
- Manufacturing is complex and costly due to its shape.
Rectangular Wing Planform
- Easiest type of wing to construct, benefiting from simple design principles.
- Generates larger wingtip vortices and downwash towards the tips, resulting in reduced effective AOA and lift at the wing tips.
Tapered Wing Planform
- Reduces downwash in the mid-wing area, improving overall aerodynamic efficiency.
- Experiences significant downwash at the tips, where tip vortices are more pronounced, potentially affecting performance.
Tapered Sweepback Wing Planform
- Downwash is maximized at the wing root and decreases towards the tips, enhancing lift near the fuselage.
- Intense wingtip vortices can lead to increased downwash, complicating flight dynamics.
Methods to Decrease Lift at Wing Tips
- Implementing washout, which involves reducing the angle of attack at the tips to lessen lift.
- Adjusting camber change, allowing for flexible wing profiles to manage lift distribution effectively.
