Abstract : A continuous force actuator having a housing, a pair of slidably mounted T-shaped pistons therein and a plurality of resilient, hallow pressure tubes surrounding each of the pistons. The insertion of fluid from the resilient tubes alters the position of the pistons relative to the housing and thereby controls the continuous force applied by the actuator. By operably connecting the continuous force actuator between opposite components of, for example, a variable configurated airfoil, continuous control of the airfoil configuration can be performed in a reliable and accurate manner.
