Abstract

Scale model testing has formed a vital part of modelling research activities, allowing modelling researchers to validate code and model set ups against experimental data. Generally, scale testing to-date has proceeded at the 1/30th to 1/20th scale which is in line with the size of facilities available for testing such devices. This paper presents a fundamental study into the effects of Reynolds Number and Rotor Solidity when testing HATTs at 1/5th scale, 1/20th scale and 1/30th scale. The paper utilises a mixture of 1/30th scale (0.5 m diameter) experimental data for two, three and four rotor setups, 1/20th scale (0.9m diameters) experimental data for a three-blade rotor setup.
