两种飞行甲板形式的舰船空气流场特性比较

搭载固定翼飞机的水面舰船受多种因素的影响,通常会采用多种飞行甲板形式,尤其是在没有配备弹射器但搭载有固定翼飞机的舰船上,是否采用滑跃式起飞甲板,采用后舰面空气流场会有哪些变化是在总布置设计必须要讨论的问题.本文通过在定常条件下,同一船型上采用的2种飞行甲板舰面布置方案进行了多个工况的空气流场模拟计算,对计算结果进行分析,观察模拟出的二维/三位流线形态,对舰船采用不同飞行甲板形式的气流场特性进行了初步的探讨.

A comparison of ships' airwakes with different flight decks

Ships which have the capability of carrying fixed-wing aircrafts would adopt different layouts of flight decks, such like the ramp-deck and the flat-deck. Especially for those ships which operating with fixed-wing units but without catapult launcher would consider about whether chose the ramp deck or not, and the influence to the ships' airwake coursed by the different laying-out of flight deck need to be discussed. A ship's general design team would always focus on the efficiency of a laying-out decision and whether it is reasonable. Also, the influences to the fixed-wing and helicopters when the flight deck's form is been changed would always be discussed. However, such influences would relatively to the safety operation on the sea. This paper simulated the airwakes of two different flight decks on one platform. The 2D/3D streamlines of different laying-out had been demonstrated. A primary discussion's expressed after the result has been analyzed.
