Abstract:
Comments are presented on the instrumentation necessary for tests of two tandemly placed hydrofoils suspended from the forward projected boom of a Sea Sled. For complete correlation of results it is required to have the simultaneous dynamic recordings of boat speed, surface wave characteristics, and the lift and drag of the two foils. Hot wire anemometers and strain gage balances used in conjunction with amplifier oscillograph combinations will yield the desired results. It is pointed out that extreme stability and steadiness of the Sea Sled proper is an absolute prerequisite to the attainment of satisfactory test results and the subsequent correlations.
