摘要
文章针对大展弦比飞机机翼挂载外挂物的状态,分别按照GJB67A-2008和CCAR-25-R4的规定,计算全机离散阵风动态响应,提取机翼及外挂物在两种规范下的动响应包线,分析阵风梯度对阵风载荷的影响,给出离散阵风动响应分析的建议。
Aiming at the high-aspect-ratio wing with stores,the dynamic response of the full-aircraft discrete gust is calculated in accordance with GJB67A-2008 and CCAR-25-R4 respectively,and the dynamic response envelope of the wings and stores under the two specifications is extracted.The influence of gust gradient on the gust load is analyzed and suggestions on the dynamic response analysis of discrete gust are given.
