摘要
M2轻型运动飞机机翼结构采用复合材料,通过静力试验对其机翼强度进行验证,对发现机翼结构设计薄弱环节以及结构改型和发展具有重要意义。首先分析ASTMF2245-16机翼强度适航条款的要求;然后通过对M2飞机载荷包线、环境影响系数、限制载荷和极限载荷的研究,计算得到复合材料机翼载荷;最后进行机翼限制载荷静力试验、机翼极限载荷静力试验和机翼破坏载荷静力试验,并对试验结果进行分析。结果表明:M2飞机的极限载荷满足试验要求,复合材料机翼试验破坏载荷相对设计极限载荷的偏差为2%,M2飞机的复合材料机翼结构设计满足静强度设计要求。
Composite material is used in the wing structure of M2 light sport aircraft.The strength of the wing is verified by static test.It is of great significance to find the weak links in the wing structure design and the structural modification and development.Firstly,the requirements of strength airworthiness clause of ASTM F2245-16 wing are analyzed.Then,the composite wing loads are calculated by studying the load envelope,environmental impact factor,limiting load and ultimate load of M2 aircraft.Finally,the static test of wing limited load,wing ultimate load and wing damage load are carried out,and the test results are analyzed.The results show that the ultimate load of M2 aircraft meets the test requirements,the deviation of the damage load of composite wing test from the design limit load is 2%,and the structural design of composite wing of M2 aircraft meets the static strength design requirements.
