Experiments on Low Aspect Ratio Hydroplanes to Measure Lift under Static and Dynamic Conditions

Abstract

In support of SUBSIM the computer program which simulates submarine manoeuvres, there was a need for data on dynamic effects on lift forces for low aspect ratio hydroplanes. A thorough literature search was carried out; previous papers usually described two dimensional experiments at much higher frequencies than those of relevant interest. It was therefore decided to perform some dedicated experiments to obtain the required data. This Technical Memorandum describes experiments in the Circulating Water Channel to measure lift forces on low aspect ratio hydroplanes under static and dynamic conditions. Empirical equations to represent the results are given.
