Estimate Center of Gravity
Calculating the position of the centre of gravity.
Description
The Estimate Centre of Gravity block calculates the position of the centre of gravity as a function of mass and the rate of change of the centre of gravity position as a linear function of the rate of change of mass. Linear interpolation is used to determine the position of the centre of gravity.
