    摘要:

    民用飞机燃油箱/滑油箱装载的燃油/滑油在惯性载荷的作用下,会对邻近结构带来冲击力,可能造成油箱结构件的疲劳或强度问题,引起油箱漏油,进而引发其他安全问题。依据第25.965条、第25.1015条中燃油箱及滑油箱晃振试验的相关要求,分析了晃振试验的适用性、验证实施及审查方式,梳理了审查风险点并提出了对应的审查重点。结合具体型号审查案例,对审查的过程及符合性判定进行了分析。分析了燃油箱、滑油箱设计特征并与条款判据进行对比,明确了25.965(b)、25.1015(b)的符合性验证思路,以说明性文件的方式进行符合性表明。通过审查案例说明,采用符合性判据,并与飞机设计特征进行对比,可直接对晃振试验的适用性及符合性进行判断。梳理总结得到的符合性判据、审查重点及风险点为燃油箱及滑油箱晃振试验的型号审查工程实践的具体实施提供了一定的参考及明确判据。

    Abstract:

    Under the action of inertial load, the fuel or oil loaded in the fuel tank/oil tank of civil aircraft will bring impact force to the adjacent structure, which may cause fatigue or strength problems of the fuel tank structural parts, cause the fuel tank to leak, and cause other safety problems. According to the requirements of the fuel tank and oil tank sloshing test in 25.965 and 25.1015, this paper analyzes the applicability, compliance implementation and methods for sloshing and vibration test, sorts out the compliance risk points and puts forward the corresponding compliance focus. Combined with compliance cases, the review process and compliance determination were analyzed. In the compliance cases, this paper analyzes the design features of fuel tank and oil tank, compares them with the clause criteria, clarifies the compliance methods of 25.965(b), 25.1015(b), and conducts compliance in the form of explanatory documents. The compliance case study shows that the applicability and compliance of the sloshing and vibration test can be directly judged by adopting the compliance criterion and comparing with the design features. This paper summarizes the compliance criterion, review focus and risk points, which provides certain references and clear criteria for the specific the specific aspects of the engineering practice of the fuel tank and oil tank sloshing and vibration test.
