设计1套局部气垫双体船模型拖曳试验方案，用于静水阻力试验。试验方案包括船模的设计、垫升系统、气垫内压强测量系统、气垫波形摄像系统等部分。试验除测量船模的阻力、纵倾角、重心处升沉，还监测气垫内压强的分布以及波形。并根据船模内外吃水情况，计算出湿表面积，采用二因次法换算出实船的有效功率。

This paper presents a partial air cushion catamaran towing tank test scheme forresistance test. The scheme includes ship model design, pressure measurement system in air cushion, waveform capture system etc. This test not only measures resistance, pitch angle, heave of gravity center, but also monitors the air pressure distribution and waveform in the air cushion. Besides, according to the draft situation inside and outside the model ship,it calculates wet surface of the model and gets the effective power by using two-dimensional method.
