船载直升机着船预报系统及评估方法

介绍船载直升机着船预报系统的硬件组成和几种常用的预报方法,提出一种基于微成分分析的新的预报方法。最后,对综合考虑横摇和纵摇2种运动的着船预报效果进行评估。

Landing Prediction System and Ship-Borne Helicopter in Rough Sea

With the presented new technology of forecasting the occasion of touchdown, ship-borne helicopter which undertakes the task of salvage or supply, can take off or land safely at rough sea. The thin-film tilt sensor and ACL-8112PG data collection card are used for ship motion measurements and analog/digital transformation. The software package logs ship motion data from the measurement system, runs the predictor and displays actual and predicted ship motions on line. The algorithm can prolong the look ahead time horizons. In order to assess whether this technique can be used to improve safety in the case that operations are restricted by ship rolling and pitching movements, an assess method is provided in the system.
