Research on Load Conditions Selection for Large Amphibious Aircraft Full-Scale Static Test
The load conditions selection of large amphibious aircraft full-scale static test was studied.According to the design load conditions and load conditions pool,the guiding principle of load condition selection for large amphibious aircraft full-scale static test is presented.According to the scope of static test,based on the analysis of critical load conditions of components,the comparison of internal force envelope and the comparison of static strength margin,the selection ideas and methods of the whole aircraft conditions and component conditions are proposed.Taking steady pitch condition at 2.5 g and engine mount as well as its attachments static test for large amphibious aircraft as examples,the selection process of the whole aircraft and components conditions is explained.The research results show that the load condition set of the full-scale aircraft static test can be given after the load conditions selecting,which can meet the purpose and requirements of engineering verification test,improve the efficiency of the full-scale aircraft static test and speed up the development of the project.This study can provide reference for the design and implementation of other large aircraft static test.
