摘　　要：针对直升机着舰过程中的下滑进场环节,从流场环境对直升机飞行品质影响的角度出发,研究了直升机着舰策略。分析了下滑进场区域的流场分布,研究表明流场的分布与距离甲板的高度相关,高度越低,气流速度均值越大,且下洗气流主要集中在迎甲板风方向的路线区域,对直升机的飞行品质造成影响。分析了不同甲板风(Wind on deck,WOD)条件下直升机平衡状态量,分别从旋翼所需功率、操纵量和机体姿态等方面对进场方式进行了研究,表明合理的进场方式有利于着舰安全。For the processes of the approach and glide-down in helicopter landing, the landing strategy of shipborne helicopter is researched to study the influence of airflow environment on flying qualities. The airflow distribution on flight deck is analyzed, and the result shows that the downwash airflow distribu- tion has relation with the flight height, that is, the lower height, the bigger airflow value. Besides, the downwash airflow mainly concentrates on the upwind approach chart, which has influence on helicopter flight qualities. The results of helicopter trim states in different wind on deck （WOD） are analyzed, in- cluding the required rotor power, control sets, body attitudes, etc, which show that the suitable ap- proach method is the beneficial to the helicopter safety during landing process.
