Parts of a wind turbine gearbox have to be lightweight and long-lasting. About two years ago, while developing automation equipment for a major wind turbine manufacturer, leaders of Advanced Design Industries Inc. realized they had a way to overcome some problems known in the industry. Support from a Lorain County Community College Innovation Grant and the Defense Metals Technology Center helped the company design and build a 125 kW prototype gearbox as well as a test bed. ADI Wind now is an offshoot of Advanced Design specializing in the new unit. ADI Wind is also developing an integrated generator, which will be placed directly with the same gearbox housing. ADI Wind is finalizing designs and working on a demonstration model to show potential investors.
