Abstract
An ullage compensator is disclosed for a stored chemical energy power propulsion system. With the invention, at least one movable wall (16) is provided within a reactor having a chamber (10) which is movable between a first position at which the chamber has a maximum reaction volume to a second position at which the reaction chamber has a minimum volume. A force is applied to the movable wall by a bellows to cause the wall to project into the chamber in response to the force when a reaction is occurring within the chamber. The invention eliminates damage to the interior surface of the chamber and the inlet port(s) for introducing an oxidant into the chamber which sustains the reaction caused by direct contact with a gaseous oxidant which causes the reaction.
