The purpose of the present investigation is to evaluate by experiment the theoretically predicted wave-making drag of ACV. The calculated wave drag of an ACV model according to the NEWMAN POOLE theory is compared with the wave drag calculated from the wave pattern measured along a longitudinal cut (NEWMANSHARMA method).
The measured wave drag shows close correlation with the theory except at low speeds. For Fn<0.5 the experiment do not show the hump drag predicted by the theory.
Why wave pattern drag has no drag rise at slow speeds seems to be reasonably explained by HOGBEN'S interpretation which pointed out the wave steepness limitations on Hovercraft wave drag.
