Oscillating Airfoil in Parallel Streams Separated by an Interface


Lo, Shih-Chun (1951) Oscillating Airfoil in Parallel Streams Separated by an Interface. Dissertation (Ph.D.), California Institute of Technology. doi:10.7907/HR3R-5994.


A new approach to tail buffeting is made by studying the problem of a thin airfoil performing a periodic oscillation of small amplitude in the presence of an interface across which the flow undergoes a constant change in density and velocity. A general solution to the problem is found. Lift and moment for some special cases are obtained in simple forms and are plotted in Figs. 3 and 4 for the two basic modes of oscillation: bending and torsion. A typical application to flutter analysis is made and it is found that tail flutter at low speeds is possible for the tail lying in the wake of the wing.
