摘　　要：本文设计的密助薄壁结构声纳导流罩，解决了大载荷情况下导流罩的强度、透声和空化问题，强度储备大于２．５倍；平均插入损失小于１．０ｄＢ，空化数为４．０时，导流罩表面无空化。设计满足使用要求。In this paper, some design features of a thin walledsonar dome with closely spaced stiffeners is de- scribed. The design improved its strength,sound transmission and cavitation performances under the condition of heavy load.The reserve strength is over 2.5 times.The average in- sertion loss is below 1.0dB; And the cavitation would not oc- cur on the dome surface when the cavtiation index equals 4.0. The design meets the requirements for use.
