Bell Helicopters has named KUKA Systems as its supplier partner for developing the manufacturing line for the new Bell 525 Relentless super medium-class commercial helicopter. Design and engineering work are under way for the Bell 525 Relentless production line, which will assemble the entire airframe. When the design is finalized and all tooling and processes are confirmed, the Bell 525 is expected to become the second largest line KUKA Systems has built in the North American aerospace sector. The largest is the Integrated Assembly Line being built for Northrop Grumman Corp. to construct the fuselage of the F35-II program. The Bell 525 Relentless will be a hybrid of composites and metal, requiring different processes and tooling. The line is scheduled for setup in Bell's Amarillo, TX, plant.
