After the invention of the airplane, its bodies, as well as internal designs, were changed to improve its efficiency and performance. Though the latest jets are updated, we find a lot of gaps in improving its capability to reach higher goals. NASA and other organizations aim to develop a domestic flight to space, and researchers and engineers work on various aspects to meet this goal. However, a simple design we observed for reducing the length of the aircraft wings was achieved by the addition of a small weir (winglets) at the edge of the wings. It even avoids the turbulence caused by the sharp tip the acts opposite to the lift.
Engineering personnel from aeronautical and mechanical backgrounds test the models with computational fluid dynamics to develop the designs and study the vortex formation during the flight. It looks simple extension but it was a break-through. Younger engineers are still working in this area to reduce the distance required for takeoff.
Some notable examples of commercial airplanes with unique wing designs include:
- Boeing 787 Dreamliner (Raked Wingtip)
- Airbus A350 XWB (Winglet)
- Boeing 747-8 (Raked Wingtip)
- Airbus A380 (Winglet)
- Bombardier CSeries (High-Aspect-Ratio Wing)
Advantages of winglets:
- It helps to reduce fuel consumption.
- It breaks the vortices formed at the tip of the wings so the opposite drag will be reduced.
Aerodynamic Design of Aircraft Wings using Computational Fluid Dynamics (CFD)
Aircraft wing design is crucial for efficient flight, stability, and maneuverability. Computational Fluid Dynamics (CFD) plays a vital role in optimizing wing aerodynamics.
