Canadian manufacturer supplies waterjet impellers to US Navy
- September 2, 2013
A Canadian manufacturer has supplied the US Navy with 2 sets of four waterjet impellers. Dominis Engineering, Gloucester, ON, is one of only a few manufacturers in the world capable of machining these large, complex rotating components, says president Bodo Gospodnetic.
The waterjet impellers, a critical component of a ship's waterjet propulsion system, were delivered to Rolls-Royce Naval Marine Inc., in support of the US Navy's LCS program.
“The completion of these impellers is an important achievement for Dominis. It demonstrates that we are a leading player in sophisticated Computer Numerically Controlled (CNC) milling of large, complex rotating components” says Gospodnetic. “Impellers and monoblock propellers are strategically important components and we are proud to have developed manufacturing capabilities which are internationally competitive.”
Manufacturing of impellers and monoblock propellers requires large parts be machined to complex curved shapes with high precision. The technology to do this economically has been developed by Dominis Engineering, which spun out of the Ship Research Laboratory of the National Research Council. The ongoing development of Dominis’ IPMS (Integrated Propeller Manufacturing System) keeps the company at the forefront of this field and allows it to bring in contracts from around the world, says Gospodnetic.
Dominis has achieved world-wide recognition for its capabilities as evidenced by its clients such as Rolls-Royce Naval Marine Inc. based in Walpole, MA, who are using Dominis high precision machining capabilities in supports of its US government market segment.
Gospodnetic says his ambition is to maintain the company’s leading position and to develop new applications for its basic technology. “Support from NRC’s IRAP and Industry Canada has been key to the company. We are now in an excellent position to bid on supply of propulsion components for NSPS (National Shipbuilding Procurement Strategy) in the coming years,” he says.
