MODAL AND FLUTTER ANALYSIS OF THE SAILPLANE LAK-17B USING NUMERICAL METHODS

摘要

The objective of current work is to determine the V–g and V–f diagrams for the sailplane’s LAK-17B empennage using numerical methods. The article considers the following problems: development of finite element model of the sailplane LAK-17B; normal modes calculation using created finite element model; flutter analysis of sailplane LAK-17B using doublet lattice method.
