Mass Properties

Description

The Estimate Center of Gravity block calculates the center of gravity location and the rate of change of the center of gravity.

Linear interpolation is used to estimate the location of center of gravity as a function of mass. The rate of change of center of gravity is a linear function of rate of change of mass.

Dialog Box

Full mass

Specifies the gross mass of the craft.

Empty mass

Specifies the empty mass of the craft.

Full center of gravity

Specifies the center of gravity at gross mass of the craft.

Empty center of gravity

Specifies the center of gravity at empty mass of the craft.
