ABSTRACT:
In an apparatus for generating a propellant gas, such as is used in propeng projectiles, at least one rotation chamber acts as a propellant gas generator containing a ring-shaped flow of propellant. A closed circuit is connected to the chamber for circulating a liquid propellant to it. Either monergolic or hypergolic propellants can be used with the rotation chamber being formed of at least two sub-chambers when hypergolic propellants are used. The two sub-chambers are connected by an overflow weir. The closed circuit which is provided for each of the chambers involved in the generation of the propellant gas, includes a valve for regulating the quantity of propellant disposed in a ring-shaped flow within the chamber. The valve regulates the amount of propellant required for the gas-generating operation. Further, the closed circuit includes an arrangement for sealing flow into and out of the rotation chamber or chambers during the generation of the propellant gas so that a rapid pressure buildup can be attained.
