The center of pressure is the specific point on a body—like a wing, rocket, or airfoil—where the total (net) pressure force from a fluid (air or water) effectively acts.
Key points:
- It represents the average location of all aerodynamic pressure forces.
- At this point, the resultant force (lift or drag) can be considered to act, simplifying analysis of stability and control.
- Its position can change with the angle of attack or shape of the object.
Examples:
- On an aircraft wing, the center of pressure shifts as the wing’s angle of attack changes, affecting pitch and stability.
- In rockets, designers ensure the center of pressure stays behind the center of mass to maintain stability during flight.
Understanding the center of pressure is crucial in aerodynamics, engineering, and design for ensuring stability and control of flying or floating bodies.
