Neural network system for estimation of helicopter gross weight and center of gravity location
First Claim
1. A system for estimating information on gross weight and center of gravity location onboard a helicopter by using variable input parameters measured during airflight in a reference frame fixed relative to the helicopter, including:
- means for generating successive signals representing said variable input parameters measured; and
means for determining from said signals the estimated information in terms of real time values of the gross weight and center of gravity location in accordance with a learned relationship.
