VSSL and Excel Pattern Works collaborate to smooth waves for U.S. Navy

Collaboration between Vibration & Sound Solutions Limited (VSSL) and Dearborn-based Excel Pattern Works has resulted in the delivery this month of a revolutionary shock-mitigating seat for U.S. Navy vessels.

The semi-active adaptively controlled seats (SAACS) were developed and fabricated by VSSL and Excel Pattern Works for the X-Craft SEA FIGHTER, a 262-foot high-speed aluminum catamaran, which was christened by the Navy on February 5 th by House Armed Services Committee Chairman Duncan Hunter (R-California) and the ship's sponsor, Mrs. Lynn Hunter.

The mission of the companies and their product: to allow the X-Craft and potentially other Navy vessels, to operate in rough sea conditions while Text Box: Navy Secretary Gordon R.

Project Manager Dr. David E. Simon notes that these problems have plagued fast-moving Navy and special operations craft and their operators for years and that the fielding of the SAACS seats represents a significant milestone. "This program marks the first application of active technology for mitigating shock to personnel aboard an operational Navy vessel."

Central to the successful fielding of the SAACS seats was the support of Excel Pattern Works Inc., which designed and fabricated the composite seat structures. "Fabricating the seat structure for this demanding application was right in our sweet spot" said Excel Pattern Work's Vice President Paul J. Maassen . "The SAACS seat, like our company, represents an ideal blend of hand craftsmanship with cutting-edge technology."

Founded in 1941, Dearborn, Michigan-based Excel has applied its expertise and 28,000 square feet of engineering and manufacturing space to a broad spectrum of companies representing automotive, aerospace, appliance, business machines, marine, and many other industries. According to Maassen, these clients continue to rely on Excel for their most demanding moldmaking, tooling, and part making requirements. "Our commitment to our customers is supported by the most advanced facilities and equipment, a staff of highly trained and dedicated technicians, and a depth of experience matched by few other companies."
