DETERMINATION OF AIRCRAFT STRUCTURE WHIRL FLUTTER STABILITY BOUNDARIES BY MEANS OF OPTIMIZATION BASED SOLUTION
Čečrdle J.
pages 42 - +16p., full text

The submitted paper deals with the aircraft structure whirl flutter analysis. It gives a summary of the regulations requirements, the theoretical background and the aircraft certification relating issues. The main part deals with determination of critical engine suspension stiffness parameters considering the structure whirl flutter stability at the certification speed. The optimization-based analytical procedure is demonstrated on the two examples. Finally, the future exploitation of the method is outlined.
