Ensuring the safety of aircraft from adverse aeroelasticity phenomena and, in particular, flutter plays an important role in creating a new aircraft. The problem is especially relevant nowadays, because intense competition in the global market requires the creation of a modern aircraft with high weight perfection. This results in minimizing the structural weight of an airframe, and, therefore, in reducing its stiffness thus decreasing flutter speed. This paper shows the methods of research into SSJ100 aircraft flutter and steps based on the analysis of research results, which have been taken to increase the critical speed of the determining flutter mode to ensure the required flutter speed margins.
