Which components do we calculate for center of pressure? Where is the distance of components while computing the cp and cg of a rocket?

everybody!

I have 4 questions about center or pressure (cp) and center of gravity (cg) of a rocket system.

Questions

1) While computing the center of pressure of rocket system, which components do we account? Are these components only components that come in contact with air or all components of a rocket system (including componenets that inside the structure of rocket)?

2)

In the above figure, we have a rocket with it's values about calculating it's center of gravity. The question is, the d-payload, d-ox, d-structure, d-fuel, d-wings values are where of the component's body? Is center of gravity or the component or most close side of the component or where?

3) The same question with 2. question but it's about center of pressure. Where is?

4)

In the above figure, we see a rocket system with it's 6 Degrees of Freedom except Thrust and Drag Aerodynamic Force. How the movement in x-axis (roll or rolling maneuver) affects rocket's flight path negatively?

Thanks!

• The coordinate frame in the second figure looks off. Assuming that the "axis" labels are in the axis "positive" directions, the "roll" and "pitch" rotational arrows seem to be in the wrong directions.
