Abstract:

Based on solving the generalized dynamic equation, and analyzing the problems of dynamic loads of the aircraft due to the ejection of an external store, various calculations were realized including the dynamic loads of ripple ejection by using Direct Matrix Abstraction Program(DMAP), the dynamic loads of a complete aircraft of unsymmetrical ejection by using a half aircraft model, and the dynamic loads of multi degree of freedom on the suspended store due the ejection of the other store. The results of calculation show that the method of this report can be effectively used to solve the different problems of dynamic loads of the aircraft.

Key words: loads, structural dynamics, external store, dynamic response
