COMPUTATIONAL EXPERTISE

Wind tunnel testing time can be reduced by finding ways to redesign fan stages using the latest aerodynamic and noise prediction software.

Hear it before you fly it!
Approximately half of the engineers in the NASA Glenn Acoustics Branch are dedicated to finding practical ways to calculate the noise generated by aircraft engines. Insight gained through fundamental research is incorporated into new computer programs by our team.

How do engine components make noise? How does that noise reach the ears of people on the ground? Which changes to the engine will make it run more quietly? Calculating noise estimates is tougher than it sounds, and NASA research is vital. Without a thorough understanding of how noise is created and spreads, there would be no reliable way to estimate aircraft engine noise.
