Coast Guard Academy cadets studying mechanical engineering here have been prototyping a new and improved rescue basket, which could revolutionize the way the Coast Guard conducts search and rescue missions with MH-60 Jayhawk helicopters.
First class cadets Christian Breviario, Riely Brande, Benjamin Crutchfield, Nolan Richerson and Spencer Smith spent the last year working closely with the U.S. Coast Guard Research and Development Centerto improve upon the current rescue basket design after receiving input from search and rescue operators in the fleet.
Coast Guard Study
“In 2009, the Research and Development Center conducted an internal Coast Guard study,” said M.J. Lewandowski, a research project manager for the RDC. “The study noted that the Coast Guard’s ability to respond to mass rescue incidents was, and still is, somewhat limited in the methods available to remove large numbers of people from a hazardous marine situation quickly and safely.”
The RDC and academy leaders approached Breviario and his capstone group at the beginning of their senior year to see if improvements could be made to the current design that would increase the Coast Guard’s effectiveness during mass rescue incidents.
“We have added a means of entry that is easier for people who may be injured or have limited mobility,” Breviario said. “We have also maximized the space dimensions of the basket, given the dimensions of the MH-60 Jayhawk cabin. With these modifications we have made the basket more accessible, decreased the amount of time needed per hoisting evolution, and improved upon the effectiveness of the Coast Guard during mass rescue incidents.”
New Basket Design
The new basket design, which is roomy enough for two individuals to sit comfortably, enables Coast Guard operators to save precious time during mass rescue situations. During mass rescue scenarios where 18 or more victims require helicopter assistance, the cadets have determined that the new basket could cut the time required to get everyone hoisted onboard by half.
“The team was tasked with improving the Coast Guard’s response in a search and rescue scenario,” said Ron Adrezin, a mechanical engineering professor and project advisor. “The RDC needed the project to meet very specific criteria and the cadets were able to produce a well-designed project that met all of these needs.”
The cadets also reconfigured the flotation system of the basket, which increased the buoyancy of the basket by 79 pounds of force. This upgrade will also allow for increased comfort of victims within the basket, as they will be surrounded by buoyant material on all sides.
Breviario and the rest of his capstone group will graduate this May with degrees in mechanical engineering and will enter the fleet as ensigns. Their project has garnered interest from the Office of Aeronautical Engineering and the Aviation Logistics Center, who will consider whether to take the project further into a refinement and testing phase.
“Their project absolutely showcases what they’ve learned during their four years as engineering students, as well as pushed them to go beyond what we taught them and learn new topics and techniques on their own,” said Coast Guard Cmdr. Matthew Walker, a mechanical engineering instructor at the academy and a pilot. “I am intrigued by the team’s approach to this project and to see where it goes from here.”
Breviario said he hopes to see the design implemented into the fleet as the new standard rescue basket used in Coast Guard operations. The capstone group is pursuing a patent for their design and waiting on the RDC to decide if they are interested in further testing.
“We feel extremely proud of what we have accomplished this semester, and along the way, we have gained a lot of traction from our sponsor and aviation operators in the fleet,” Breviario said. “We would love to see our project make it to the fleet in the future, but even more so we feel that we have taken the next steps in providing a solution to a problem the Coast Guard faces on numerous occasions each year.”
