displacement hull

基本解釋

A method for predicting the hydrodynamic property and motion of high-speed displacement mono-hull ship based on 2.
發(fā)展了基于二維半理論的預(yù)報(bào)排水型單體船在波浪上的水動力特征及運(yùn)動性能的方法。
A fast semi-displacement hull, on the other hand, is inefficient at low speeds when the transom tends to sink deeper in the water.
快速半排船體則是在低速航行時(shí)較為低效率，因?yàn)榇碓诘退俸叫袝r(shí)吃水更深。
Its innovative design is based on a semi-displacement hull that is quite narrow in the beam, allowing it to reach 30 knots or more with modest power.
它創(chuàng)新的設(shè)計(jì)在于擁有較窄船梁的半排水船體，使得其能夠在中等動力下獲得超過30節(jié)的航速。
