摘要
在低速条件下,由于流场不稳定,飞机出现抖振、高度下降等情况,导致传统的静压源传感器无法测得精确的数据。目前常用的DGPS加拖锥的方法也存在局限性,通过试验对比分析,表明采用扩展卡尔曼滤波算法可以结合测试数据得到较好的失速速度。
Vibration and descent may happen on the aircraft at low speed due to unstable air flow, so the traditional static pressure sensor can＇ t get accurate data. The currently used DGPS also has some limita- tions. By test comparison and analysis, it is indicated that the extended Kalman filter together with the test data can be used to get more accurate stall speed.
