A new 3-wire probe is presented,which is mainly used to measure the aft-deck flow field of a carrier model. A survey of three-dimensional flow field of the aft-deck has been worked out. Mounting the carrier model on a truck and running straight on the runway,the test was carried out. The setting angle 5 between the symmetrical plans of the model and the truck may be changed to meet the wind incidence requirements. It is revealed that a dead-water zone formed on the front of aft-deck is quite complicated. This...

A new 3-wire probe is presented,which is mainly used to measure the aft-deck flow field of a carrier model. A survey of three-dimensional flow field of the aft-deck has been worked out. Mounting the carrier model on a truck and running straight on the runway,the test was carried out. The setting angle 5 between the symmetrical plans of the model and the truck may be changed to meet the wind incidence requirements. It is revealed that a dead-water zone formed on the front of aft-deck is quite complicated. This is the first example in China. Through this test,more experiences of hot-wire techniques in field work are accumulated. Beside those outlined previously,the development of a 3-wire probe,the method of data acquisition and processing in field work,and the result and analysis of flow field around the aft--deck of a carrier model are briefly discussed.

针对车载舰模后甲板流场测量,开发了一种三丝热线探头,测量出三维流场速度和方向。试验是在汽车载着舰船模型沿机场跑道直线行驶下进行的,通过改变模型与车身轴线的夹角β,以满足试验时不同合成风向的要求。结果表明,模型甲板前沿流动分离形成一定的"死水区",流场十分复杂。车载规模试验在国内尚属首例,它为热线技术在外场测试的发展积累了一些经验。文中还阐述了三丝热线探头研制、工作原理、处理方法、外场数据测量及舰船模型后甲板流场测量结果分析等。

In this paper, the dynamical properties of a ship model which was equipped with the floating draft installation were investigated. The finite element analysis was carried out with ANSYS software and the performance of vibration isolation was surveyed through the experiment. Aiming at reducing the energy of structure-borne sound of the ship, the three-dimensional finite element model was setup and then analyzed in which the floating raft system and the ship were treated as a whole. Based on the factors of non-rigidity foundation as well as the damping and rigidity of isolators, the optimization of structural parameters was discussed. The way to improve the good quality of vibration and sound reduction was investigated, and then a series of conclusions which are valuable in engineering were derived.
