Abstract

A Lightning Protection System (LPS) was designed and built at Launch Complex 39B (LC39B), at the Kennedy Space Center (KSC), Florida in 2009. This LPS was instrumented with comprehensive meteorological and lightning data acquisition systems that were deployed from late 2010 until mid 2011. The first direct strikes to the LPS were recorded in March of 2011, when a limited number of sensors had been activated. The lightning instrumentation system detected a total of 70 nearby strokes and 19 direct strokes to the LPS, in 2011, 2 of the 19 direct strokes to the LPS had two simultaneous ground attachment points (in both instances one channel terminated on the LPS and the other on the nearby ground). In addition to the 70 nearby strokes, some more distant nearby strokes where captured on video records for which limited data were acquired. Instrumentation deployment chronological milestones, a summary of lightning strikes (direct and nearby), high speed video frames, downconductor currents, and dH/dt and dE/dt typical waveforms for direct and nearby strokes are presented in this paper.

2011年佛罗里达肯尼迪航天中心39B发射场直接和附近雷击的总结

雷电防护系统(LPS)于2009年在佛罗里达州肯尼迪航天中心(KSC)的发射综合体39B (LC39B)设计和建造。从2010年底到2011年中期，该LPS配备了综合气象和闪电数据采集系统。第一次对LPS的直接攻击发生在2011年3月，当时激活的传感器数量有限。雷电仪表系统共检测到70次近雷击和19次对LPS的直接雷击，在2011年，对LPS的19次直接雷击中有2次同时有两个地面附着点(在这两种情况下，一个通道在LPS上终止，另一个在附近的地面上终止)。除了70个附近的笔划外，还有一些较远的附近笔划被记录在视频记录中，这些记录获得了有限的数据。本文介绍了仪器部署时间顺序里程碑、雷击(直接和附近)、高速视频帧、下导体电流以及直接和附近雷击的dH/dt和dE/dt典型波形。
