Pressure in the context of aircraft design refers to the force exerted by a fluid (usually air) per unit area. It is an essential parameter in aerodynamics and aircraft performance calculations. Pressure can vary at different points on an aircraft’s surface and within the airflow around it, influencing lift, drag, and other aerodynamic forces.
Pressure Formula: The formula for pressure (P) is defined as:
- Pressure (P): Pressure is measured in pascals (Pa) in the International System of Units (SI). 1 Pascal is equal to 1 Newton per square meter (N/m²).
- Force (F): The force applied by the fluid (e.g., air) is typically measured in newtons (N).
- Area (A): The area over which the force is applied is measured in square meters (m²).
