Aeroelastic Problems Associated with High Speeds and High Temperature

Summary

Two simple examples of aeroelastic effect are given in which chordwise distortion is important. The first relates to static distortion of a solid wing at high temperature using non-linear relations derived by Mansfield. It is shown that the chordwise distortion is stabilising as regards divergence, but leads to considerable loss of lift. The second example shows that chordwise distortion can reduce the flutter speed of a flat plate.
