On-Water Motion Relationships Study

Abstract

This report presents an on-water head seas motion analysis of three C/STOL and three V/STOL sea based aircraft configurations. Heave, pitch, acceleration, and slamming/wetness conditions are determined. Different forward speed conditions were studied. The effect of various configuration parameters (length, inertia, c.g. location, water plane area, etc) on head seas motion parameters was established. Sea state conditions from one to seven were studied. Fundamental sea state relationships and their effect on sea basing of aircraft are presented. Recommendations for subsequent model tank testing are indicated.
