GENERAL RESISTANCE TEST OF A SHALLOW STEP PLANING HULL WITH APPLICATION TO A HYDROFOIL CONFIGURATION.
Abstract
General resistance tests of TMB Model 4335-2, a shallow-stepped planing hull, were conducted. This hull is the second in a series of planing hulls to be tested by the general resistance method to determine its suitability for use as a hydrofoil hull. Resistance, trimming moment, and wetted length were measured for several load, trim, and speed conditions. All data are presented in nondimensional form for use in comparing hull forms. The tests showed that the model has high resistance and is unstable due to afterbody wetting at certain combinations of trim, speed, and load conditions that might be encountered at some time during takeoff and landing. The high resistance and instability appear to be the result of spray interference and step ventilation problems. (Author)
