风浪中船载直升机着船预报仿真系统

Landing Predicting System for Ship-Board Helicopter in Waves

实施海上搜救、垂直补给的船载直升机,可以藉助着船时机预报新技术,在大风浪中安全着船。本系统利用膜电位姿态测量系统和ACL8112PG数据采集卡完成数据采集和转换,利用软件包记录数据,并进行实时的预测和数据显示;利用多步预测算法来延长预报时间,并对综合考虑横摇、纵摇和垂向速度三种运动的预测效果进行评估。本系统可以自动生成海浪时历和舰船摇荡时历,为研究直升机着船的安全性提供仿真平台。

Using the new technology to predict the touchdown occasion, the ship-borne helicopter undertaking the task of salvage and supply, can land safely in waves. The thin-film tilt sensor and ACL-8112PG data collection card is used for ship motion measurement and analog/digital transform. The software package logs the motion data from the measurement system, runs the predictor, displays actual and predicted motions on line. The algorithm can prolong the look-ahead time horizons. An assess method is provided to assess whether this technique can be used to improve safety on operations which are restricted by limits on both of three channels of roll, pitch and heave. The system can generate waves and ship motion experiences automatically. It's a simulation platform for the safety research of ship-borne helicopter's landing.
