Spring 2017 Newsletter – Measuring Center of Buoyancy

Understanding mass properties, such as center of gravity, makes it possible to design and build stable objects and to predict their performance in a medium such as air or water. With aircraft, the center of lift is the point where the sum total of all lift generated by parts, principally by wings, control surfaces, and aerodynamic fuselage parts, balances out and the aggregate direction their force will act on a craft while in an atmosphere. Similarly, the performance of a submersible marine vehicle depends on its center of buoyancy. The center of buoyancy of an object is defined as the point that would be the center of gravity of the displaced fluid, not the submersed object itself. Until now determining the center of buoyancy was primarily done using calculations or indirect measurement. Raptor Scientific has devised an instrument to experimentally determine center of buoyancy to an accuracy previously unattainable. Determining the geometry of the measurement system and validating the theory has been completed with a working instrument ready for shipment to the customer. The instrument is capable of measuring multiple axes with a center of buoyancy accuracy of 0.1″. The new instrument will begin testing at the customers’ facility this spring.
