MTS Systems, a global supplier of high-performance test and simulation systems and sensors, completed the acquisition of R&D Group, which designs and manufactures test systems that accurately simulate the extreme operating environments often encountered by large, rotating structures, such as wind turbines, and aircraft engine propulsion systems, for $80m. "We are very excited about adding R&D to the MTS family as we continue to expand our technical offerings and customer applications in the Test & Simulation space. With their demonstrated success in the wind energy market, and successful expansion into aerospace propulsion applications, R&D has delivered strong growth momentum and margin performance which we believe is sustainable as we leverage the MTS global sales and service infrastructure. Moreover, the combination of MTS’s long history of innovation in materials and structures testing for the energy and aerospace markets, in combination with the added capabilities of R&D, will position MTS as an even more valuable partner to these rapidly growing customers and markets around the world," Dr. Jeffrey Graves, MTS President and Chief Executive Officer.
