摘　　要：从试飞安全的角度出发,对直升机不可逾越速度下降转弯试飞动作进行研究。首先,理论分析了直升机不可逾越速度下降转弯试飞过程中可能存在的风险点;其次,针对可能存在的风险点,以某型直升机试飞为例,在该机上完成相关飞行状态参数、振动参数,以及载荷参数传感器的加装和校准工作;同时在该科目试飞过程中,对直升机上关键的飞行状态参数、关键振动参数和关键载荷参数进行实时监控,保证了该型直升机不可逾越速度下降转弯试飞的安全,为后续直升机试飞安全进行技术积累。This paper based on the load spectrum flight test of some helicopter, researching the item of helicopter descending and turning at the velocity never to exceed. First of all, theoretically analyzed the possible risks while helicopter doing the item, for the possible risks, mount sensors and complete the calibration of sensor before helicopter fly, to measure flight state parameters, vibration parameters and load parameters. During the whole item flying, monitored the above key parameters. It not only guarantees the safety of the helicopter＇s spectrum flight test while doing the item, but also establishes a reliable method for this items.
