Innovative weight and balance measurement system for Tiltrotor application


The WEIBAL project aims at developing a complete measurement system able to detect the 3D position of the Centre of Gravity (CoG) of the plane in different configurations on ground. This will be done through the development of four subsystems: the scales, an elevation platform for the front wheel, a system to measure the relative position of the scales and the measurement of the pressure footprint in the scales. This will be complemented with an analysis of uncertainties to control and minimize the measuring error, both in the mass and in the relative positions of the scales.
The achievement of this main objective is complemented with four specific objectives for the innovation activities driving to its development. These specific objectives are related to the development of the different subsystems needed for the WEIBAL measurement system, including the measurement footboards, the distance measurement systems, the actuation system to modify the configuration of the system and an additional system to monitor the load application point in each footboard, i.e. the footprint.
