Abstract

In order to solve the technical problem that the dynamic compensation for lever arm effect in transfer alignment of airborne weapon, an improved dynamic compensation method for lever arm effect was proposed. Firstly, through the establishment of the flexure model of wing, the nominal dynamic lever arm vector under flexural deformation was obtained. Then, combining with the dynamic lever arm, the dynamic compensation mechanism of lever arm effect was analyzed in detail. Finally, the proposed method was analyzed and validated by using the "velocity plus attitude" matching transfer alignment model. The simulation results show that the proposed method can effectively solve the dynamic compensation problem of lever arm effect.

Key words： airborne weapon; transfer alignment; flexure deformation; lever arm effect; velocity plus attitude matching
