Abstract

In order to meet the need of modern war, rapid and accurate initial-alignment has become one of key technologies in the field of inertial technology. Finite element model and unsteady aerodynamics model of the whole machine structure is constructed in this paper. The sin gust disturbance is added under some flight condition, the writer elucidates vibration Influence for the transfer alignment about the dynamic interference source influence through the time-domain response analysis of the master and sub-inertial navigation.
