The acoustic beacon,which installed in the cone shell of a flying vehicle,exists big deviations between the actual installation location and theoretical installation location, leading to the cutting trajectory not be accurately generated. Therefore, a method of new trajectory design is proposed,including measuring, programming, cutting and detection. First, the actual location of the acoustic beacon is measured, and established the relationship between the spatial position and the measurement reference position through the coordinate system. And then cutting trajectory control algorithm,acoustical beacon space position control point and axial vector calculating method are designed. In this way, we verify the correctness of the cutting path, propose optimization for post-processing,constrain the rotation angle of the device and check the cutting path characteristics. At last, we make sure the acoustic beacon spatial position control point corresponds to the axial vector measurement data by test verification. The proposed method is reasonable, reliable and effective.
