According to Bernoulli's principle, how is lift generated in aircraft?

• A. Faster air flow over the wing creates high pressure
• B. Slower air flow under the wing creates low pressure
• C. Faster air flow over the wing creates low pressure
• D. Wings must be flat to create lift

Answer: (C)

Lift generation in aircraft according to Bernoulli's principle is primarily explained by the relationship between the speed of airflow and the pressure exerted by that air. When the wing of an aircraft moves through the air, its shape causes the air to travel faster over the top surface than it does underneath. This faster airflow results in a decrease in pressure above the wing, creating a pressure difference between the upper and lower surfaces. This pressure difference is what generates lift, which allows the aircraft to rise. The principle specifically highlights that as the speed of the airflow increases, the pressure decreases. Hence, the faster air flow over the wing is responsible for creating low pressure, which effectively lifts the aircraft. Understanding this principle is crucial for comprehending how different wing designs and flight dynamics affect an aircraft’s performance and stability in the air.
