Abstract
A staged rocket apparatus includes first and second stages connected by a releasable connector. A plurality of pressurized gas struts are connected between the first and second stages and provide a separating force urging the first and second stages apart. The gas struts are held in a telescopingly collapsed first position by the releasable connector. The separating force is maintained at a minimum value so long as the releasable connector holds the struts in their first position. When the releasable connector is disconnected the separating force increases due to gas flow through a metering passage having a progressively increasing flow area from a high pressure chamber to a low pressure chamber.
