Wants to reduce noise from aircraft

​With better simulations of aircraft noise, aircraft manufacturers can produce components that produce less noise without giving other negative consequences.
Doctoral student Daniel Lindblad has worked with calculating noise from aircraft engines using computer simulations. They are usually cheaper to perform than physical tests, which means that those who manufacture components can afford to test several different variants of each component before moving on and testing the best alternatives in real life. However, for the selection process to be as good as possible, the simulations must be reliable.

In my PhD project, I have worked with evaluating and improving existing models, which also contributes to an increased understanding of the methods used today” says Daniel Lindblad.

Several areas where improvements can be made

Daniel's research has shown that today's methods are already very well developed, which underlines the competence that exists in the aviation industry and aviation research today. However, there are several areas where improvements can be made, and Daniel Lindblad is happy that he has been able to contribute to this.

“I have mainly contributed to an increased understanding of the advantages and disadvantages of different methods for simulating noise from aircraft. I have also suggested improvements to several methods, which hopefully means that future simulations will be better” says Daniel Lindblad.

By collaborating with the University of Cincinnati and the German Aerospace Center (DLR), both of which have strong ties to the industry, he hopes that the results will also be adopted in practice.

Daniel Lindblad will defend his dissertation Numerical Methods forAeroacoustic Analysis of Turbomachines on September 25 at 14.00.
