Zjednodušený aeroelastický průkaz pro malý sportovní letoun

Abstract

The master thesis deals with a simplified aeroelastic proof of a small sport airplane of ultralight aircraft category. To determine the current requirements of this category there is carried out research of selected construction regulations in a field of aeroelastic loading. A proof of absence an aeroelastic phenomena is performed by Simplified Flutter Prevention Criteria method and there is researched possibility if this methodology could replace a rational flutter analysis. As a part of the requirements of the Simplified Flutter Prevention Criteria method among others a modal analysis of the airplane is performed. Analysis is performed with respect to simplicity of the method in obtaining sufficiently accurate results. In the conclusion there is made an evaluation of a simplified aeroelastic proof of the airplane. According to this evaluation there is carried out a discussion in the field of an aeroelastic control of ultralight category.
