舰载机着舰下滑道指示一致性分析

Analysis of Carrier-Based Aircraft Landing Glideslope Indications Consistency

针对着舰引导系统中各设备出现引导偏差,提出下滑道指示一致性指标。对“肉球”偏移和飞机下滑偏移之间的关系进行分析;分别在光学助降装置和中线相机出现引导误差时,对舰载机着舰点和下滑偏移量产生的影响进行仿真计算。对下滑道指示一致性进行分析,计算光学助降装置和中线相机的引导不一致引起的“光球”偏移量。通过仿真验证,可以将一致性指标作为是否需要对系统进行标校的一个依据。

Aiming at the problem that the guidance deviation of each equipment in the system affects the safety of landing,an index of the consistency of the landing glideslope indications was proposed.The relationship between“meat ball”offset and aircraft glideslope offset was analyzed and calculated.When the guidance errors of optical landing aids and midline cameras occur,the impact of landing point and glideslope offset of carrier-based aircraft was analyzed and simulated.The consistency of glideslope indications was analyzed,and the“meat ball”offset caused by the inconsistency of guidance between optical landing aids and midline cameras was simulated and calculated.Through simulation,consistency index can be used as a basis for system calibration.
