The Center of Pressure (CP) of a rocket is defined as:

The Center of Pressure (CP) is indeed defined as the point at which aerodynamic forces, including lift and drag, are effectively concentrated. This point is critical in rocketry because it determines the stability of the rocket during flight. When a rocket moves through the air, aerodynamic forces act differently on various parts of the rocket, and the CP is where these forces can be considered to act as a single point.

When the CP is located correctly in relation to the Center of Gravity (CG), the rocket will be stable; that is, it will tend to stay pointed in the direction of its flight. If the CP is behind the CG, the rocket will be inherently stable, whereas if it is in front of the CG, the rocket may become unstable and could tumble or veer off course.

Understanding the CP is crucial for designing rockets that can fly successfully, as it plays a key role in ensuring stability and control during flight. This knowledge helps rocketry enthusiasts when they are designing their rockets, positioning fins, and calculating expected flight paths.
