Abstract
An apparatus for creating on-command buoyancy is provided with an elastically deformable and axially elongated watertight hollow shell having a plurality of leaf springs and enveloped by a flexible skin. When flattened, the shell has a small internal volume and is negatively buoyant. The hollow shell is held in this position by a latch mechanism. When the mechanism is released, the leaf springs expand to increase the internal volume of the shell. In this state, the system is buoyant. A release mechanism for the latch bar is provided in a forward closure to permit transition from negatively buoyant to a buoyant configuration when an external signal is received.
