Nicole Sharp<p><strong>Quietening Drones</strong></p><p>A drone’s noisiness is one of its major downfalls. Standard drones are obnoxiously loud and disruptive for both humans and animals, one reason that they’re not allowed in many places. This flow visualization, <a href="https://www.youtube.com/watch?v=5yaAFLpLmVg" rel="nofollow noopener" target="_blank">courtesy of the Slow Mo Guys</a>, helps show why. The image above shows a standard off-the-shelf drone rotor. As each blade passes through the smoke, it sheds a wingtip vortex. (Note that these vortices are constantly coming off the blade, but we only see them where they intersect with the smoke.) As the blades go by, a constant stream of regularly-spaced vortices marches downstream of the rotor. This regular spacing creates the dominant acoustic frequency that we hear from the drone.</p> Animation of wingtip vortices coming off a drone rotor with blades of different lengths. This causes interactions between the vortices, which helps disrupt the drone’s noise. <p>To counter that, the company Wing uses a rotor with blades of different lengths (bottom image). This staggers the location of the shed vortices and causes some later vortices to spin up with their downstream neighbor. These interactions break up that regular spacing that generates the drone’s dominant acoustic frequency. Overall, that makes the drone sound quieter, likely without a large impact to the amount of lift it creates.

Graham Dunning<p>A trip to the Dungeness sound mirrors at the weekend. This is the only place in the UK that all three designs can be seen in the same place. On an island in a nature reserve, they're only accessible up close a handful of times a year. </p><p>These were pre-radar aircraft detection devices. Initially human listeners with stethoscopes would listen to pinpoint the direction of incoming zepelins and aeroplanes (the two dish-shaped reflectors). Later an array of microphones using heated wires across the large rectangular reflector were used, with trigonometric calculations giving location results. The rectangular reflector is a segment of a 200 foot sphere, giving a much longer focal range.</p><p>The common misconception is that the invention of radar put the mirrors out of commission. In fact, we were told by the military history enthusiast at the site, they were made obsolete due to the increasing speed of air travel. Initially planes could be detected giving 30 minutes notice. As speeds reached 400mph+ it only took a few minutes to cross the channel anyway, so the detection time was as good as useless. </p><p><a href="https://post.lurk.org/tags/acoustics" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>acoustics</span></a> <a href="https://post.lurk.org/tags/concrete" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>concrete</span></a> <a href="https://post.lurk.org/tags/brutalism" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>brutalism</span></a></p>
