Archangel Awarded SBIR Contract to Study Continuous Estimation of CG (Center of Gravity), Inertial and Loading (CECIL)

Archangel Systems, Inc. announced today that it has been awarded a Phase I Small Business Innovative Research (SBIR) contract to study the feasibility of a technical and forward-thinking solution for optimized vehicle loading: the Continuous Estimation of CG (Center of Gravity), Inertial and Loading (CECIL). The investigation will determine the sensors and algorithms for continuous monitoring of both CG and load. Simulated measurements and algorithms extracts total load, load distribution, CG in three dimensions, and how all three change throughout the mission, both during the loading process and during operation. Advanced algorithms detect signature changes in a vehicle’s dynamics in real time which are mapped to CG shifts and weight changes. This investigation compares optimized conventional methods of load sensors for weight estimation to the proposed inertial method to show a full picture of feasibility. Furthermore, algorithms project the vehicle dynamics forward in time and input the future vehicle state to a 3-D model for the vehicle’s stability along with the CG and loading measures. The model computes future rollover risk and alerts the crew before rollover is imminent.
