Watertight Model Self-Propulsion Propeller Dynamometer

This additional sealing equipment can be taken out easily and can be replaced by the sealing arrangement for use in ship models in the towing tank in order to reduce friction So if the additional equipment for use of the dynamometers in a cavitation tunnel is ordered, the dynamometers are also suitable for use in ship models in a towing tank. In the first case, they are provided only with a sealing arrangement suitable for sealing against water pressure whereas in the latter case, they are supplied with additional equipment that seals the propeller dynamometers against relatively high vacuum and against pressure up to 1 bar above atmospheric pressure.
