USA: Bluefin, NRL Round Off Long-Endurance UUV Mission

first_img View post tag: Navy View post tag: Defense View post tag: Endurance View post tag: Bluefin Bluefin Robotics, a Quincy-based provider of Unmanned Underwater Vehicles (UUVs), announced that the company, in support of the Naval Research Laboratory (NRL), has successfully completed a long-endurance UUV mission from Boston to New York totaling over 100 hours with NRL’s Reliant “Heavyweight” UUV.The multi-day mission exercised UUV autonomy methods and demonstrated the capability of a high capacity energy configuration. Further, the endurance test was designed to push the boundaries of traditional UUVs with the objective to uncover the challenges and requirements for significantly extending UUV endurance for new applications. The exercise is part of a series to support NRL’s research in UUV-based technology for the US Navy.Reliant, is an advanced version of the Bluefin-21 vehicle and, when equipped with a Low Frequency Broadband (LFBB) sonar payload, is the prototype SMCM UUV Knifefish system for the US Navy. The vehicle navigates using a fiber-optic gyro-based INS along with supplemental data from a GPS and a Doppler Velocity Log (DVL) to enable precise navigation underwater for long endurance missions. Reliant utilizes Bluefin’s modular vehicle design that enabled the team to easily remove the payload section and add additional energy sections increasing the system’s energy capacity to nearly 40 kWh of power. Configuration took place over only a few days at Bluefin’s headquarters in Quincy, Massachusetts.The team mobilized the vehicle on the Boston Harbor Cruise’s, M/V Matthew J. Hughes, and deployed it outside Boston Harbor. To optimize for endurance and range, the vehicle traveled at an average speed of 2.5 knots at 10 meters water depth, resurfacing every 20 kilometers for navigation updates over GPS. Team members on M/V Matthew J. Hughes and onshore were able to receive vehicle status information over Iridium satellite system. While the support vessel was available, it did not provide navigational updates to the UUV, leaving the system to travel completely autonomously. After 109 hours of operation and transiting over 500 kilometers through strong currents, the system successfully reached its end point in New York Harbor with 10% of its battery life remaining.The overall effort was funded by the Office of Naval Research.[mappress]Press Release, October 31, 2013; Image: Bluefin Robotics View post tag: Naval View post tag: Defence View post tag: News by topic View post tag: Mission View post tag: NRL View post tag: Long View post tag: Round Back to overview,Home naval-today USA: Bluefin, NRL Round Off Long-Endurance UUV Mission Equipment & technology Share this article View post tag: usa October 31, 2013 View post tag: UUV USA: Bluefin, NRL Round Off Long-Endurance UUV Missionlast_img read more
