dc.description.abstract |
This report describes work which has been done to investigate the possibility that the flexure-torsion flutter speed of a wing may be less at high incidences than at low incidences, and that this decrease may be due primarily to reduction of aerodynamic torsional damping with incidence. The main discussion is contained in Part I., but the evidence dealt with here is obtained from tests made at relatively very low Reynolds numbers. Part II. (p.11), however, discusses the application of the results to full scale, and is based on more recent tests at larger Reynolds numbers. It is concluded that for modern aircraft the variation of critical speed with incidence is likely to be small. |
