Abstract:

A flexible nose assembly for an underwater vehicle provides increased energy-absorbing capabilities and facilitates recovery and handling of the vehicle. The flexible nose assembly includes a flexible nose cap, at least one retrieval device, and at least one cable that is strong in tension, yet weak in compression which is coupled between the retrieval device and the UUV body. The flexible nose cap has a gap formed therein allowing the communication of environmental water into the region between the vehicle body and the nose cap. Optionally, the retrieval device may be recessed into the flexible nose assembly, thereby reducing hydrodynamic drag and overall vehicle length. Energy-absorbing ballast can be positioned within the nose cap in order to further enhance survivability.
