Flagmill -A new power generator utilizing flexible sheet-

Journal of Fluid Science and Technology, 2015
The present study proposes “a flagmill”, which is a new power generator utilizing the flutter of a flexible sheet such as a flag. The sheet flutter causes the angular oscillation of the supporting pole. Since the supporting pole is connected to the power

Flutter and forced response of mistuned rotors using standing wave analysis [PDF]

, 1983
A standing wave approach is applied to the analysis of the flutter and forced response of tuned and mistuned rotors. The traditional traveling wave cascade airforces are recast into standing wave arbitrary motion form using Pade approximants, and the ...
