About

Rotor Dynamics Test Facility at AERDC, HAL Bangalore for evaluation of the functional and operating characteristics of Rotor-Bearing-Support system. The Rotor Dynamic Test facility covered under this tender includes the design, manufacturing, supply and commissioning of equipment, systems, software, spares and any other tools if any not explicitly mentioned in this specification required for the smooth functioning of the facility. The test facility proposed is of generic nature for Rotor Dynamic testing of Rotor-Bearing-support systems covering various configurations such as both sides over hanging, simply supported, one side over hanging etc.
