I am trying to wrap my head around drag separation, particularly as it applies to nose cones.
Definition: Drag Separation - The unintended (or in a few cases, intended) separation of bodies while in flight that occur after motor burnout, due to the inertia of one section having more force to separate the bodies than another section has force to keep the bodies together.
As I understand it, the heavier a nose cone is, the more prone it will be to drag separate with high thrust motors.
Can someone show me the way to calculate out these forces? I did a cursory search and didn't find much.
With this knowledge, it would be easier to make a determination on when to think about the use of shear pins.
