Click image to enlargeAn Ottawa, ON, manufacturer has developed a cost-effective machining process for complex impellers and propellers and just completed delivery of a series of its machined products for the US Navy. 

Dominis Engineering manufactured a series of monoblock propellers for Wärtsilä Defense, Inc., in support of a US Navy’s program.

The propellers are critical components of a ship’s propulsion system. “The completion of these monoblock propellers is an important achievement for Dominis and demonstrates that we are a leading player in sophisticated machining of large and complex components” says Bodo Gospodnetic, president, Dominis Engineering. “Propellers and impellers are strategically important components and we are proud to have developed capabilities which are internationally competitive.”

Manufacturing of impellers and propellers requires that 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 over twenty years ago. 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.

Dominis has achieved world-wide recognition for its capabilities as evidenced by business such as the machining of water jet impellers and monoblock propellers for Wärtsilä Defense, Inc. Wärtsilä Defense, based in Chesapeake, VA supports the U.S. Government market segment, primarily with sales and service of marine propulsion equipment and shaft sealing solutions.

In addition to marine propulsion systems, Dominis has the capabilities to manufacture components for hydro-electric turbines, power systems and large compressors. Ongoing development of software systems and specialized tooling is the core of the company’s business. 

Gospodnetic’s ambition is to maintain the company’s leading position and to develop new applications for its basic technology. The Company is positioned for growth and expects to bring new products to market in the next two years while continuing to supply critical components in the marine propulsion sector.
