Abstract

The practical application of the flutter analysis during the design of the sailplane is presented. Preliminary calculations are done in parallel with technical documentation. Ground vibration test and stiffness measurement results are used for data correction and computing model verification. The precise flutter clearance calculation finally decided the design of the sailplane. Results of KR-03 PUCHATEK sailplane analysis are presented as example.
