Linear Actuator for Large Space Structure.
Abstract
The impending use of large structures in space has created a requirement controlling their alignment. Structures used for energy gathering, such as antennas or solar energy concentrators, must maintain accurate mechanical alignment in order to operate at maximum efficiency. This paper describes a linear actuation approach designed to meet the alignment requirements of space structures. The approach is based upon using a fluid pump to expand and contract two chambers enclosed by metal bellows. The general configuration is valid for a wide range of force, rate and stroke requirements required for different structure designs.
