Modeling, experimental research and critical parameter analysis of glider’s dynamic characteristics

Abstract

The work studies results of glider dynamical characteristics modeling and ground tests. It presents a methodology of defining natural frequencies of glider structure and parameters characterizing flutter phenome-non, analysis of developed means designated for perform-ance of glider ground frequency tests. The paper presents results of modeling of resonant frequencies of LAK-17B glider structural elements, which are compared to experi-mental results of ground dynamical tests. The efficiency of application of the demonstrated methodology allows defin-ing possible flutter phenomena of structural elements of the mentioned glider and their vibration decrements.
