Image: Evaluating the noise of future aircraft

As air traffic continues to surge in the U.S., neighbors who live near airports are complaining about the escalating noise. All the while, the demand for faster aircraft that travel at supersonic speeds is accelerating.

Low pressure reduces bubble trouble

Spray coating and inkjet-based electronics manufacture are among the industrial applications in which liquid droplets are applied to a surface. But minuscule air bubbles that get trapped beneath the droplet as it lands can ...

New study changes view on flying insects

For the first time, researchers are able to prove that there is an optimal speed for certain insects when they fly. At this speed, they are the most efficient and consume the least amount of energy. Corresponding phenomena ...

Bats anticipate optimal weather conditions

Millions of animals fly, swim or walk around the Earth every year. To ensure that they reach their destination, they need to perceive precise changes in environmental conditions and choose the right moment to set off on their ...

Big data project aims to make breathing easier

Heavy city traffic contributes significantly to air pollution and health problems such as asthma, but UT Dallas researchers think another kind of traffic—data traffic—might help citizens better cope with pollution.

Fast and loud—how to create sonic booms and curious clouds

Growing up beneath the Concorde flight path, I learned early on that if you heard its characteristic roar overhead you had to look far towards the horizon to see it. If you were lucky, you would see Concorde first. You could ...

Designing ice repellent materials

Materials that actively repel water and ice very strongly are sought after by the aviation industry and for many other technical applications. ETH researchers have now found out how to specifically design the rigid surfaces ...

Falling faster—researchers confirm super-terminal raindrops

Five years ago, a research team at Michigan Technological University and Universidad Nacional Autanoma de Mexico (National University of Mexico) detected tiny, super-fast raindrops. The finding was unexpected—small drops ...
