Abstract
A flap actuator for adjusting the orientation of a flap or the like, the actuator. The actuator includes: a static arcuate member having a radius of curvature; a piezoelectric motor biased to be in operable contact with the static arcuate member; a housing for housing the piezoelectric motor; and a flap orientation shaft operably connecting between the housing and the flap. The distance between the shaft and the static arcuate member is essentially equal to the radius of curvature of the static arcuate member.
