摘　　要：针对通用飞机失速警告装置防冰验证缺少具体的技术标准和指导资料的现状,开展相关技术研究。按照25部附录C中的连续最大结冰条件、间断最大结冰条件以及失速警告装置防冰功能延迟启动条件分别提出三项验证符合性要求;建立以冰风洞试验为核心的验证技术和验证方法,论述试验模型设计技术要求以及适用的试验相似准则技术。针对冰风洞试验结果无法满足更临界的防冰功能延迟启动符合性要求情况,提出在《飞行手册》的操作程序中增加专门的等效安全规定和限制。所论述的验证要求和验证技术在某型通用飞机失速警告装置防冰验证中具体实施并获得适航当局的认可,为进一步建立和完善失速警告装置防冰验证的通用技术要求提供参考和借鉴。This paper starts research on anti-ice validation technology for the stall warning device of general aviation aircraft based on the fact that no detailed relevant standards and references are present. Three validation compliance requirements are proposed under corresponding conditions of Part 25 Appendix C’s continuous maximum icing, Part25 Appendix C’s intermittent maximum icing, and anti-ice function activation delay of the stall warning device. The validation technology and methods are established through adoption of icing wind tunnel tests, and test model’s design requirements, as well as applicable test similarity criteria. Special equivalent safety requirements or limits are suggested to add in AFM’s operation procedures for occurrence of test results that can not meet the more critical compliance requirement under anti-ice function activation delay of the stall warning device. The proposed validation requirements and validation technology in this paper are applied in a stall warning device’s anti-ice validation program of a general aviation aircraft and are accepted by airworthiness authorities, which can provide further references for establishing and perfecting a general technology requirement for stall warning device’s anti-ice validation.
