Systems and methods for underwater descent rate reduction |
摘要 |
Systems and methods for underwater descent rate reduction are provided. In one embodiment, a method for underwater descent rate reduction for an underwater delivery vehicle is provided. The method comprises: opening a first valve based on a first hydrostatic pressure to permit water to flow into a first chamber of a hydrostatic pressure driven piston assembly; developing a pressure differential across a piston head separating the first chamber from a second chamber of the hydrostatic pressure driven piston assembly; pushing the piston head into the second chamber to extend a piston rod from the hydrostatic pressure driven piston assembly; and pivoting a deflecting flap downward into a direction of vehicle descent as the piston rod extends.
