Abstract:

The two-dimensional flutter equations of Theo dorsen are modified to approximate three-dimen sional circulation and virtual mass conditions. This is accomplished by multiplying the circula tion and virtual mass terms of the two-dimensional equations by appropriate factors. The circula tion factor is the ratio of the three-dimensional to the two-dimensional steady lift expressions. The virtual mass factor is the ratio of the three-dimensional to the two-dimensional virtual mass expressions. Results of the modified analy sis are compared with results obtained experi mentally for a foil with aspect ratio of 3.0 and analytically from the two-dimensional theory. Author
