摘　　要：为了评估舰载直升机的着舰飞行品质,依据舰面起降任务特点构建了着舰任务科目试飞评估方法,并开展了舰载直升机着舰飞行品质试飞评估。首先,对直升机不同着舰方式的任务科目进行了驾驶员主观定性评估;然后,基于频域法对着舰过程中直升机的操纵及响应特性开展了客观定量分析。结果表明:同一起降位以艉弦进入方式着舰的驾驶员操纵品质等级评定结果优于左舷进入方式,而同样是艉弦进入方式,靠近艉弦的起降位着舰优于远离艉弦的起降位;同时,直升机对于高频操纵输入的幅频及相频响应特性与驾驶员操纵品质等级评定结果具有一定联系。In order to evaluate the carrier landing flight quality of carrier-based helicopters,a flight test evaluation method for carrier landing mission task element was constructed based on the characteristics of surface take-off and landing missions and the flight test evaluation of the landing flight quality of a carrier-based helicopter was carried out.Firstly,the pilot subjectivity of the mission subjects of different landing methods of the helicopter was carried out.Then,an objective quantitative analysis of the helicopter’s handling and response characteristics during the landing process was carried out based on the frequency domain method.The results show that the pilot handing quality ratings with the stern entry method are better than the port side entry method for the same take-off and landing position.By the stern entry method,landing in the take-off and landing position close to the stern string is better than that far away from the stern string.At the same time,the helicopter’s amplitude-frequency and phase-frequency response characteristics for high-frequency control inputs have a certain connection with the evaluation results of the pilot’s handing quality ratings.
