中文摘要:
      为了拓展活塞式发动机安装架适航审定思路,对《正常类、实用类、特技类和通勤类飞机适航规定》(CCAR23-R3)、《航空 发动机适航规定》(CCAR-33-R2)及甚轻型(AC-21-05)、超轻型(AC-21-06)飞机适航标准中规定的活塞式飞机发动机安装架设计 要求进行分析,给出了活塞式发动机安装架结构设计载荷工况计算、强度分析和试验验证方法。结果表明:活塞式发动机安装架主 要采用超静定多路传力桁架结构设计;活塞式发动机安装架正常载荷工况共11 组;活塞式发动机安装架静强度分析主要考虑管 材拉压弯剪及焊接接头与螺栓连接接头强度。
英文摘要:
      In order to expand the airworthiness certification of piston engine mounting bracket,the design requirements of piston engine mounting bracket set out in Airworthiness regulations for normal,practical,aerobatic and commuter aircraft (CCAR23-R3), Airworthiness requirements for aeroengines (CCAR-33-R2)and very light type(AC-21-05)and super light type (AC-21-06)were analyzed. The design load condition calculation,strength analysis and test verification method of piston engine mounting bracket were given. The results show that the piston engine mounting bracket mainly adopts the design of superstatic multi-way force transfer truss. The piston engine mounting bracket have eleven groups under normal load conditions. Static strength analysis of piston engine mounting bracket mainly considers pipe tension bending shear and joint strength of welded joint and bolt joint.
