摘要
侧滑角是一个重要的飞行状态参数。考虑飞机真实的飞行状态, 选取快速存储记录器(QAR)中的磁航向、偏流角、风向、风速、地速和俯仰角等参数, 提出一种基于QAR数据的民航飞机侧滑角估算方法。以飞机受西风影响为例, 通过分析4种航向范围的航行速度三角形, 再利用地面惯性坐标系、机体坐标系和气流坐标系之间的变换关系, 推导了侧滑角估算步骤, 最后选取一段QAR数据对侧滑角进行估算。结果表明该方法能够有效地利用QAR数据对飞机侧滑角进行估算。
Abstract
Sideslip angle is one of the important flight status parameters.Considering the true aircraft flight status a method for estimating the civil aircraft sideslip angle based on quick access recorder (QAR) data was proposed by selecting magnetic heading drift angle wind direction wind speed ground speed pitch and some other parameters from the QAR.The aircraft under the influence of westerly was taken as an example and the sideslip angle estimation procedure was derived by analyzing wind triangles of four kinds of heading and using the transform relationship among the earth-surface inertial reference frame body reference frame and wind coordinate frame.Finally a piece of QAR data was selected to estimate the sideslip angle.The result shows the effectiveness of this method.
