摘要
为了使国内涡扇发动机满足吞雹试验验证需求,得到有效的吞雹能力验证,根据GJB241A-2010、CCAR-33R2标准中吞雹试验的相关要求,开展了涡扇发动机吞雹试验方案设计方法研究,总结了方案设计过程的经验.通过吞雹试验相关标准的内涵解析和实际应用场景分析,研究了冰雹数量、冰雹速度、发动机工作状态、撞击位置等试验参数的具体设计方法.通过研究国外相关试验中冰雹投射情况,确定了冰雹投射方案的设计和评估方法,明确了针对投射方案的仿真分析方法.以上试验方案设计方法在某发动机上得到验证,能够为涡扇发动机吞雹试验方案设计提供参考和指导.
Abstract
In order to meet the requirements of hailstone ingestion test verification for domestic turbo-fan engines and obtain effective hailstone ingestion capability verification,according to the relevant re-quirements of hailstone ingestion test in GJB241A-2010 and CCAR-33R2 standards,the design method of hailstone ingestion test scheme of turbofan engine was studied,and the experience of the design pro-cess was summarized.Based on the analysis of the connotation of standards related to hailstone inges-tion tests and practical application scenarios,the design methods of the test parameters,such as hail-stone quantity,hailstone speed,engine working state,and impact position were studied.By studying the hailstone projection scheme in relevant foreign tests,the design and evaluation method of the hailstone projection scheme was determined and the corresponding simulation analysis method was defined.The test scheme designed according to the method was verified on a certain engine,which can provide refer-ence and guidance for the design of the hailstone ingestion test scheme of the turbofan engine.
