Abstract:

A model investigation was undertken to define the effects of waves, loading, and hydrodynamic configuration on the over-all take-off performance of waterbased aircraft. Complete take-offs were made using dynamic models towed at constant thrust in calm water and in regular waves. Performance is evaluated by means of the average resistance-to-gross-weight ratio obtained from the time-distance-velocity measurements made during take-off. At a given loading, average resistance increases in proportion to wave height for take-offs made in wavelenghts on the order of twice the hull length. Curves are presented showing the effects of loading, and comparisons are made between the different configurations tested. The model data show trends generally similar to those of available full-scale take-off results, when take-off time and distance are properly defined. Author
