  • 摘要:
      目的  舰载机着舰过程是其整个飞行过程中的一个关键环节,由于受到舰船运动的影响,技术难度较大。
      方法  基于舰船极短期运动预报,开展舰载机着舰过程的仿真研究。首先,基于传统的舰船极短期运动预报方法,采用波形匹配和仿射变换,提出一种最优预报算法的确定方法;然后,建立基于光波束导引的舰载机着舰导引系统模型,并提出3个衡量着舰导引系统性能的终端误差指标;最后,开展舰载机着舰过程的仿真研究,分析舰载机对光波束运动轨迹的跟踪偏差及落点分布,得到着舰终端误差。
      结果  由仿真结果可知,舰载机的着舰点相对集中,大多位于理想着舰点范围内,着舰终端误差满足着舰引导系统规范的要求。
      结论   研究成果对于舰载机的着舰引导具有参考价值。

     

    Abstract:
      Objectives  Aircraft carrier landing is the key part of the whole flight process of carrier-based aircraft, and the technology design is difficult due to ship motion.
      Methods  Based on the extremely short-term prediction method, this paper develops an aircraft landing simulation. First, based on the traditional extremely short-term prediction of ship motion, a method is proposed for determining the best prediction method by matching the waveform of the predicted signal combined with affine transformation. Next, an aircraft carrier landing guidance system is built on the basis of light beam guidance, and three landing end point errors for measuring the landing guidance system are presented. Finally, the aircraft carrier landing process is simulated, the errors between ideal approach path and tracking error of landing aircraft analyzed, and landing end point errors obtained.
      Results  It can be seen from the simulation results that the landing points of aircraft are relatively concentrated, with most located within the scope of ideal landing points. The end point errors satisfy the requirements of landing guidance system standards.
      Conclusions   The simulation results in this paper offer great reference value for the study of aircraft carrier landing.
