Using multiphysics simulation to reduce airport noise challenges
Thursday, April 20, 2017

Airport noise regulations have tightened in the last decade, making it ever more difficult to operate in urban environments. At the same time, the demand for air travel has been growing.

Airport airframers have been searching for ways to reduce the level of perceived noise caused when aircraft land. To that end, innovative companies like ATA Engineering recently demonstrated a prototype aircraft drag management device called an engine air-brake (EAB) in a series of ground tests.

The EAB uses a deployable swirl vane mechanism to switch the operation of a turbofan’s exhaust stream from thrust generation to drag generation during the approach and/or descent phase of flight. The drag generated could enable operational benefits such as a slower, steeper, aeroacoustically cleaner flight on approach.

The testing was the culmination of a 27-month Phase II Small Business Innovation Research (SBIR) project sponsored by NASA. During the course of the project, ATA Engineering used leading simulation tools to develop the aerodynamic design and tailor its performance to multiple competing design constraints.

This On-Demand webinar provides an overview of the technology maturation process and illustrate some of the ways simulation was utilized to satisfy design objectives.
