摘　　要：舰载机弹射过程中的高加速度有利于提高舰/机惯导的传递对准速度,但高速运动带来的误差也会影响传递对准的性能。本文对舰载机的弹射流程、拖拽方式、弹射时间、弹射过程中线运动及角运动规律等进行分析,从舰载机弹射时间、舰机相对运动规律,及基准信息来源等对传递对准匹配方法的约束,基准信息精度与品质、动态杆臂误差,及大失准角误差等方面对传递对准性能的影响等,论证实现舰/机惯导传递对准的可行性,提出相应的传递对准方案,并提出各种干扰误差的相应补偿方法。研究表明,舰/机惯导弹射中,基于速度匹配的传递对准方法,可以实现舰载机紧急起飞情况下的快速初始对准。High acceleration of the process of carrier-based aircraft catapult is useful to improve the speed of the transfer alignment of the carrier-based aircraft INS,but will also affect the performance of the transfer alignment caused by the high-speed movement.The carrier-based aircraft ejection process,drag method,ejection time,and the midline movement and angular movement in ejection process had been analyzed in this paper.Considering the constraints of the transfer alignment including the carrier-based aircraft ejection time,the law of relative motion of ships and planes,and the reference source of information,and considering the influencing factors of the transfer alignment including the accuracy and quality of baseline information,dynamic lever arm error,and large misalignment angle error at the same time,the feasibility of transfer alignment methods in the process of carrier-based aircraft catapult has been demonstrated,and all kinds of interference corresponding error compensation method had been proposed.Study shows that the transfer alignment based on the velocity matching in the process of carrier-based aircraft catapult can achieve rapid initial alignment in the case of carrier-based aircraft were scrambled.
