What effect does changing the camber of a wing have on lift?

• A. No effect on lift
• B. Increases thrust
• C. Reduces drag
• D. Increases the coefficient of lift

Answer: (D)

Changing the camber of a wing influences the airflow characteristics over the wing, and as a result, it directly impacts the lift generated. When the camber is increased, the curvature of the wing changes, which alters the pressure distribution around it. This enhanced curvature enables the wing to generate more lift at a given angle of attack because the air traveling over the top of the wing moves faster and creates a lower pressure area compared to the bottom surface. The coefficient of lift is a dimensionless number that reflects the lift characteristics of a wing design at a specific angle of attack. An increase in camber effectively raises this coefficient because the wing can produce a larger amount of lift under the same flight conditions. Therefore, the correct answer acknowledges that modifying the camber increases the coefficient of lift, which is crucial for improving aircraft performance during various stages of flight.
