John Glenn, from Cambridge, was the first to orbit the Earth. Neil Armstrong, from Wapakoneta, was the first to walk on the Moon. Judith Resnik, from Akron, was the second woman in space. Today, the NASA Glenn Research Center, near Cleveland, runs over 500 specialized research and test facilities.

Global Analytics

Spire Global is one of the world's largest spaceto-cloud analytics companies, providing global weather-forecasting services for the maritime and aviation industries as their satellites travel around Earth.

Noise Generation

The noise from jet-engine exhausts can cause substantial hearing loss for crewmen and airport personnel and activate restrictive regulations and/or fees for airlines. The large turbulent eddies within the jet plume—also known as large-scale coherent structures—produce the majority of the noise in the aft angles of the engine.

Jet Propulsion

For all the different moving parts that go into mechanical engineering systems, the gas turbine is a relatively simple design: a large rotor fitted with vanes is made to revolve by a fast-moving gas flow.

Optimized Fluidic Control

The roar of jet engines is the major source of noise created by commercial and military aircraft, which are bound by numerous stringent noise regulations. A research team led by Ephraim Gutmark, Ph.D., D.Sc., at the University of Cincinnati, is leveraging both experimental and computational tools to optimize existing aircraft noise suppression techniques and to develop new ones. 

Chen developing improved turbomachinery simulation software

Turbomachinery, such as that found in compressors and turbines, is instrumental in today's aeronautic, automotive, marine, space and industrial power generation. To achieve the most efficient propulsion and power systems, engine designers must understand the physics of very complex air-flow fields produced within multiple stages of constantly rotating rotors and stators.
