고속 활주선의 저항성능 개선에 관한 연구

Abstract

The development of optimum forms for planning hull is a unique

technical problem, It is necessary to study some experimental data for

the improvement of planning hull performance.

However there's bot so many model test or experienced data for planning hull forms as those for displacement hull forms.

It seems worthwhile to consider some of the systematic approach and

analysis by carrying out model tests.

Some experimental evaluation techniques for special type of hull from -

planning hull from - are introduced.

The optimum speed and trim angle are decided by obtained data of

resistance, trim, heave, wetted area, proposing tendency and diving

tendency.

As a result of study generating cavitation on the bottom of planing

hull is recommended to reduce frictional resistance.
