... were individually routed to a common transducer using a 48-channel rotary Scanivalve. The tap diameters were 1.6 mm except near the leading edge where 0.8 nun diameter holes were used. Pressure differences between these on-foil taps and a reference tap located approximately two chord lengths upstream...

... in tangential and radial planes of each probe. Thirty singleended pressure transducers were used, one for each hole in each of five probes, to measure pressures. The transducers resided below the waterline, making air purging practical. Calibration required forty one runs. Defining!, a polar angle, ~. for each...

... a destroyer model in pure heave and pure pitch modes in calm water. One purpose was to measure the added mass and damping coefficients. As well, the model was instrumented with 19 pressure transducers to measure the radiation pressure on the model hull as function of oscillation frequency, amplitude...

The load cells chosen for the discussion in this paper are considered to have a wide variety of applications. transducer gauge plane submarine hull instrument subsea system application design...

... The design of high-performance ships (SES, Hydrofoil, Swath) frequently involves the determination of secondary (wave impacts) loads. An inability to accurately determine wave impact pressures analytically necessitates model testing to provide this in formation. Conventional pressure transducers...
