Abstract
The invention is directed to an actuation system that is contained within a divided pressure vessel which has two chambers under pressure, separated by a common partition and piston. The system is operated by causing an opening in the first chamber, creating a pressure differential between the two chambers which causes the piston to move and fluid to flow between the two chambers. Movement of the piston may or may not expose flow orifices between the two chambers. Pyrotechnic material is enclosed within the piston to generate combustion products for augmenting performance. The two chambers can be used to contain inert working gases or reacting fluids that are isolated from one another until the system is actuated.
