摘要
随着火箭发射频次的提高,全天候发射的需求日益增长。为研究火箭动力系统电子设备在雷雨天气下的适应性,首先对火箭动力系统常见的电子设备进行了插脚注入试验。结果表明,与集成电路或精密仪器相关的接口对雷电敏感,需要采用雷电防护措施。继而详细介绍了浮地电路和接壳电路的雷电防护电路设计方法,并提出了瞬态电压抑制二极管(TVS)的选型参数计算方法。最后通过试验验证了所设计的雷电防护电路的有效性,该电路能够将雷电间接效应降低到可接受的水平。该研究为掌握火箭的综合雷电防护技术,提高火箭全天候发射的可靠性和安全性提供了有力支持。
With the increasing frequency of rocket launches,the demand for all-weather launch capabilities is on the rise.To evaluate the adaptability of the equipment to thunderstorm conditions,pin injection tests were conducted on typical electronic equipment utilized in rocket propulsion systems.These tests confirmed the susceptibility of the devices to lightning indirect effects.The tests identified lightning sensitivity in interfaces associated with integrated circuits or precision instruments,necessitating lightning protection measures.Detailed descriptions of lightning protection circuit design methodologies for floating ground and shell connection circuits were provided.Additionally,parameters for selecting transient voltage suppressor(TVS)were proposed.Test verification confirmed that the designed lightning protection circuit effectively mitigates lightning indirect effects to an acceptable level,thereby safeguarding the electronic equipment.This research contributes to the advancement of comprehensive lightning protection technology for rockets,thereby enhancing the reliability and safety of all-weather rocket launches.
