Dynaspede offers a Moment of Inertia measuring equipment for computation of moment of inertia of liquid contained in tanks along different axes.

For measurement for roll moment of inertia:
The equipment provides a self-contained platform needed to conduct studies on different liquids, contained in different container shapes in order to determine its roll Moment of
Inertia along its Centre of Gravity or with reference to any axis of rotation displaced from its CG. The equipment has a DSP-based control system for high-speed sampling and computation.
Although designed for measurements on liquids, the instrument is equally suitable for direct measurement of MOI of solid bodies of any geometric complexity, falling within the capabilities of the equipment.

While the operating principles are based on well-known concepts of a torsion pendulum, the design of this measuring equipment is proprietary to Dynaspede with many outstanding features in comparison to hitherto known forms of this equipment.

For measurement for pitch /yaw axis moment of inertia and the centre of gravity:
The instrument, in its present form, is designed to provide a self-contained platform needed to conduct studies on liquids filled to required levels and capped within scale models of propeller tanks to determine the location of CG (about hinge point) with and without liquid; computation and display of Lateral M.I. of liquid about an axis passing through its own CG and Damping characteristics.

This equipment is operating on the Principle of Compound Pendulums.
