Abstract
Steady state results of lift developed by varying the
momentum blowing coefficient (C(ϻ)) upon a refurbished
Circulation Control Rotor (CCR) airfoil section were favorable.
This thesis was an experimental investigation to
quantitatively evaluate whether the steady state results
could be applied by a quasi-steady assumption when a harmonic
perturbation of C(ϻ) was superimposed upon the steady
value. Results suggested an attenuation in the dynamic
transfer function of dC(p)/dC(ϻ) as the oscillating blowing frequency was increased.
