Watertight Propeller Dynamometer

Code: LBNY-0005-1970001

The Watertight Propeller Dynamometer of high capacity is sealed against pressure of up to 1 bar above atmospheric pressure and against relatively high vacuum (1 bar = 10 to the power 5 N/m2 = 0.1 MPa). Idle friction of t…

Open Water Podded Propeller Dynamometer

Code: LBNY-0005-1970002

The necessity to support the international ship model testing community with the provision of a Podded Propeller Dynamometer has therefore become imperative the need to carry out tests to establish the hydrodynamic and o…

Ship And Yacht Model Balance

Code: LBNY-0005-1970003

The balance is then connected to the model via a light weight carbon fiber composite free heave towing post, that has height adjustment as well as being free to heave, fitted with a linear transducer for the measurement …

Contra Rotating Propeller Multi Purpose Propulsion Dynamometer

Code: LBNY-0005-1970004

The Contra Rotating Propeller Multi Purpose Propulsion Dynamometer is a generic design for use either within a large Cavitation Tunnel or within underwater models in the Towing Carriage. The design greatly simplifies the…

Watertight Model Self-Propulsion Propeller Dynamometer

Code: LBNY-0005-1970005

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…

Open Water Propeller Dynamometers

Code: LBNY-0005-1970006

The propeller dynamometers are new designs to replace earlier dynamometers only adjustments to the inclination of the propeller shaft could be made, but with the introduction of the adjustment of propeller shaft height c…

Traditional 3 Component Resistance Dynamometer

Code: LBNY-0005-1970007

Equipment is designed for the measurement of resistance and alteration of draught and trim during tests with relatively small ship models on smooth water and in waves.…

Electric Open Water Propeller Dynamometers

Code: LBNY-0005-1970008

The dynamometers can be supplied with the standard height of the vertical streamlined profile or with an increased height of the vertical streamlined profile as described below. The three dynamometers are of the same gen…

Multi Component Balances

Code: LBNY-0005-1970009

However it is suitable for smaller ship models than would otherwise be used. The balance is of the same general type as the balance. …

Electric Single Component Balances

Code: LBNY-0005-19700010

Both balances serve mainly for measurements of forces acting on models which are either towed with the help of a towing carriage through a towing tank, or which are tested in a circulating water channel. Both balances h…

CRP Dynamometers

Code: LBNY-0005-19700011

It is therefore possible to control the speed of the forward and the rear dynamometer independently from each other. All 3 CRP dynamometer types have separate driveshafts for the forward and rear dynamometer to facilitat…
