Aircraft Crashworthiness
It’s a bit frightening but in the past, to understand how safe an airplane was, engineers had to wait for a crash. There wasn’t much physical testing that could be done, like with cars.
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.
CERAMIC COMPONENTS
Aviation industry manufacturers have traditionally relied upon conventional metals and alloys for constructing internal engine parts. During operation, these engines can generate sufficient heat to raise temperatures to within 50 degrees of the melting point of the nickel-based superalloys, titanium, aluminum and steel used in engine construction.
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.
Understanding airflow at transonic speeds
The complex unsteady airflow characteristics of certain aircraft features, such as landing gears and weapon bays, produce pressure fluctuations that reach unacceptable levels for operation and safety at transonic speeds.
Ablation model measures hypersonic gas plumes
Scientists are developing hypersonic aircraft that can travel at speeds beyond Mach 5 (3,800 mph) and travel from New York to London in less than an hour. In military applications, flight above Mach 8 will be needed for effective homeland security. Several technical obstacles remain, however.
