Marine Dynamic Test Facility: recent experiments with the prototype

The Marine Dynamic Test Facility (MDTF) is a 5 DOF captive hydrodynamic model test apparatus being jointly procured by the Canadian Department of National Defence (DND) and the National Research Council of Canada (NRC). This apparatus (Fig. 1) is being built by Bombardier Inc. of Montreal and is exp...

A submarine model will generally be sting-mounted and can be rotated in roll using a hydraulic actuator. The alternative strut mounting option is also available both for surface ships and submarines, particularly when propulsion systems are to be installed in the latter (Fig. 3).

Between the MDTF and the recently acquired PMM for IMD's ice tank, a whole range of captive tests can now be done for a wide range of ship types.
