摘　　要：本文重点研究带自动驾驶仪的“海豚”直升机的纵向飞行品质。文中首先给出自动驾驶仪的调节规律,继而列出装备有自动驾驶仪的单旋翼带尾桨式直升机的无量纲运动方程。其次,编制FORTRAN程序,在IBM-4341计算机上对悬停、小速度、中等速度和大速度前飞共五个速度进行调参研究。最后,按照我国航空工业部新近发布的《军用直升机飞行品质规范》对悬停、小速度和中等速度、大速度两类状态进行分析与讨论,并且得到了满意的评价。In this paper, emphasis was put on the study of longitudinal flying qualities for 'Dauphin' helicopter with autopilot equipment. At first, control law of the autopilot equipment was given, then the non-dimensional dynamic equations of the single rotor helicopter with autopilot equipment were derived. The next, FORTRAN routine was programed, and the influence of various parameters were investigated on the IBM4341 computer for five velocities (including hovering, low speed, medium speed and high speed). Finally, two conditions for hoveriag,lowspoed and forward flight were analyzed and discussed according to 'Military Helicopter Flying Qualities Specification' which was issued newly by Ministry of Aeronautical Industry of China, sad satisfactory assesments were acquired.
