- Chapter 5: Physics for Aviation › Angle of Attack
relative wind is the angle of attack. As the angle of attack increases, the lift on the wing increases. If the angle of attack becomes too great, the airflow can separate from the wing and the lift will be destroyed ... When this occurs, a condition known as a stall takes place. Figure 5-56. Venturi with a superimposed wing. There are a number of different shapes, known as planforms that a wing can have. A wing in the shape…
- Chapter 5: Physics for Aviation › Boundary Layer Control
keeping the boundary layer air under control, or lessening its negative effect, is to make the wing’s surface as smooth as possible and to keep it free of dirt and debris. As the friction between ... surface of the wing increases, the boundary layer thickens and becomes more turbulent and eventually a wing stall occurs. With a smooth and clean wing surface, the onset of a stall is delayed and the wing can operate…
- Chapter 5: Physics for Aviation › Supplemental Lift-Modifying Devices
drop down slightly, a slot opens, which lets some of the high-pressure air on the bottom of the wing flow over the top of the flap. This additional airflow over the top of the flap produces additional lift ... Fowler flap attaches to the back of the wing using a track and roller system. When it deploys, it moves aft in addition to deflecting downward. This increases the total wing area, in addition to increasing the wing camber…
