theo_lift¶
Theodorsen’s solution for lift of aerofoil undergoing sinusoidal motion.
Time histories are built assuming:
a(t)=+/- A cos(w t) ??? not verified
- \(h(t)=-H\cos(w t)\)
param w: | frequency (rad/sec) of oscillation |
---|---|
param A: | amplitude of angle of attack change |
param H: | amplitude of plunge motion |
param c: | aerofoil chord |
param rhoinf: | flow density |
param uinf: | flow speed |
param x12: | distance of elastic axis from mid-point of aerofoil (positive if the elastic axis is ahead) |
