As airline travel peaks for the Thanksgiving holiday, a newly completed wind tunnel at the University of Florida may help reduce the noise of commercial airplanes as they fly over homes and neighborhoods.
The tunnel is one of only a handful in the country and currently the largest at a university designed specifically to reduce noise from planes passing overhead and landing. Engineers will use the $400,000 tunnel to learn how to reduce the noise caused by the flow of air over wings, flaps and landing gear – the primary sources of the annoying sound that reaches people on the ground when planes are landing.
“During approach for landing, the dominant noise comes from the airframe as opposed to the jet engines,” said Lou Cattafesta, a UF associate professor of mechanical and aerospace engineering. “We need to understand where the noise is coming from, how it is generated and how we can reduce it. That’s what this facility is geared toward doing.”

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
