Abstract: | This article introduces the dynamic analysis of Super-Frelon helicopter mounted home- made blades.The test results of vibration level equipped itself blades and Z8A ones are given out and analyzed by contrast.According to the specification of ADS-27,vibration intrusion index,vi- bration level of 1p/rev and on panel are calculated and analyzed the compliance with ADS-27.At the same time the article presented the calculation results and contrast analysis of ground resonance of Super-Frelon helicopter mounted both blades.Through vibration level contrast measuring and a- nalysis and the contrast calculation of ground resonance,the definite conclusion is made out that the project of Super-Frelon helicopter mounted homemade blades is feasible,which provided guarantee for the safety of Super-Frelon helicopter mounted homemade blades in flight. |
