无人机飞行品质评定准则探讨

Discussion on flying qualities evaluation criteria of UAVs

基于无人机的任务特性,建议按照任务快速性与精确性的要求将无人机飞行阶段重新划分为4个阶段;在此基础上借鉴有人机飞行品质主观评定方法,修改给出了适用于无人机飞行品质主观评定的Cooper-Harper评价尺度;然后以纵向飞行品质客观评定准则为例,分析了有人机飞行品质评定准则对于无人机飞行品质评定的适用性,认为部分有人机飞行品质准则可借鉴应用于无人机飞行品质评定,但其准则边界必须针对无人机的飞行特性进行修改。通过研究,初步形成了无人机飞行品质评定准则研究框架,对无人机飞行品质评定具有一定的参考价值。

Based on the task characteristics of Unmanned Aerial Vehicles（ UAVs）,we proposed flight phases of UAVs to be divided into four phases,according to the control requirements of aggressiveness and precision. Referring to Cooper-Harper rating scale for the piloted aircraft,a Cooper-Harper rating scale for evaluation of UAVs flying qualities was raised. Illustrated by the case of longitudinal flying qualities criteria,applicability of the piloted aircraft flying qualities criteria to UAVs flying qualities evaluation was discussed. Research results indicate that a part of the piloted aircraft flying qualities criteria can be applied to evaluate UAVs flying qualities,but with modifications to margins of the criteria. This research work has a certain reference value for the evaluation of UAVs flying qualities.
