Abstract

Lever-arm effect and flexure are the major error factors for transfer alignment of carrier aircraft´s INS which affect the speed and accuracy of transfer alignment. The conditional compensation method of lever-arm effect is directly compensated according to the value which is gotten from calculation with the angular velocity and angular acceleration with lever-arm length under thinking the lever-arm length is fixed. Because of the influence of wave and so on, the flexure will be caused and the lever-arm length will change with the flexure. The new model of lever-arm effect with flexure was built according to analysis variability of lever-arm length with flexure, with the simulation, the relationship between the flexure and lever-arm acceleration is given and rationality of model is validated.
