Description
技术领域Technical field
本发明涉及飞机破损安全技术领域，特别涉及一种备份设计的飞机静不定吊挂结构。The invention relates to the technical field of aircraft damage safety, and in particular to a backup-designed aircraft statically unstable suspension structure.
背景技术Background technique
现有飞机的吊挂结构设计有两种思路，一种为静不定吊挂结构方案，如图1所示，C919及波音系列飞机采用此种方案；一种为静定吊挂结构方案，如图2所示，空客系列飞机采用此种方案。There are two ideas for designing the suspension structure of existing aircraft. One is a statically indeterminate suspension structure scheme, as shown in Figure 1. This scheme is adopted by C919 and Boeing series aircraft; the other is a statically indeterminate suspension structure scheme, such as As shown in Figure 2, Airbus series aircraft adopt this solution.
静不定吊挂结构对应的中接头、上支撑杆接头、下支撑杆接头均为单结构设计，如果单个接头发生破损，传力路径将发生改变；静定吊挂结构对应的吊挂上前接头、吊挂上后接头、耳片均采用备份设计，如单个接头发生破损，传力路径不发生改变。The middle joint, upper support rod joint, and lower support rod joint corresponding to the statically indeterminate suspension structure are all single-structure designs. If a single joint is damaged, the force transmission path will change; the upper front joint of the suspension corresponding to the statically indeterminate suspension structure , The rear joints and lugs of the suspension are designed with backup. If a single joint is damaged, the force transmission path will not change.
基于现有技术，有如下缺点：Based on the existing technology, there are the following shortcomings:
1、如采用静不定吊挂结构方案，导致结构在破损安全条件下，吊挂接头载荷过大，导致下壁板厚度增厚，下壁板增重明显；1. If the statically indeterminate hanging structure scheme is adopted, the load on the hanging joints will be too large when the structure is damaged and safe, causing the thickness of the lower wall plate to thicken and the weight of the lower wall plate to increase significantly;
2、如采用静定吊挂结构方案，导致应急断离设计困难，较难实现吊挂与机翼之间的分离，确保机翼油箱的安全。2. If the static suspension structure is adopted, it will be difficult to design the emergency disconnection, and it will be difficult to separate the suspension from the wing to ensure the safety of the wing fuel tank.
