Improved Solution of Whirl Flutter Using MSC.NASTRAN
Original language description
This paper deals with whirl flutter of turboprop aircraft structures. Paper is focused on the improved solution of propeller blade forces, that is used for the whirl flutter analysis using MSC.NASTRAN program system. First, paper gives an overall theoretical background on whirl flutter phenomenon. After that, propeller blade forces solution and the applicable options of a blade force modeling are described. The problem is demonstrated on the example of a twin turboprop aircraft structure. The influenceon the propeller aerodynamic derivatives and the influences on the whirl flutter (flutter speed and flutter margin) is evaluated.
