Mitsubishi Heavy Industries (MHI) has awarded Flow International Corporation a second-round multimillion-dollar contract to supply MHI with Flow's composite waterjet machine tool to cut the carbon-fiber wing components for a major commercial jet aircraft program.

Flow's composite waterjet machining system for the precision machining of carbon fiber composite stringers will measure 80ft long. It will be utilized for cutting the composite stringers, which are part of the composite wing structure.

As a result of breakthrough development work, it will be equipped with multiple patent-pending "side-fire" nozzles. The system will be built and tested in Jeffersonville, IN, one of Flow's six worldwide manufacturing plants. The UHP pumps that provide the ultra-high-pressure water will be made at the Kent, WA, headquarters.

"The second-round award of Flow's commercial wing structure machining system proves the effectiveness of Flow's waterjet technology and its ability to create 'state of the art' aircraft parts in a cost-effective manner," says Charley Brown, Flow's president and CEO.
