The Use of Ship Model Basins for the Study of Vortex Wake Phenomena.

Abstract

The basic differences between tests in air and in water are discussed relative to the study of aircraft vortex wake phenomena. It is shown that use of large ship model basins is valid for simulation up to critical Mach numbers of flight. Free surface interference is shown to be negligible for tests made at sufficient towing depths and is avoided at typical towing speeds. Effects of Reynolds number mismatch on the test results is analyzed and it is concluded that wing profile drag coefficients should be matched between full and model scale. Consideration is given to the problem of stopping and starting disturbances in towed-model testing. (Author Modified Abstract)
