POSTER: computer news   ||   THE NEW SHAPE OF BLADES WILL REDUCE THE NOISE LEVEL CREATED BY HELICOPTERS	DATE:2017-03-29
Electromobiles move around the ground almost silently.  It is much more difficult for other participants of the movement to learn about the approach of an electric vehicle, so in many countries a requirement is made to equip such vehicles with noise generators that, when driving at low speeds, would prevent pedestrians from approaching the vehicle. Meanwhile,  fewer companies want to create electric aircrafts - various aircrafts on electric traction, for the management of which in the future a pilot license will not be required, since everything will be done by automatics.  Similar plans are borne not only by the American and European aerospace agencies, but also by the largest manufacturers of passenger airliners, as well as by Elon Musk and Google founder Larry Page. As the resource Golem.de notes, German specialists have developed blades shape  , which will reduce the noise of the helicopter during takeoff and landing by 5-6 decibels, which will be subjectively perceived by the man as a reduction of "noise irritation" by half.  The first owner of blades of a new shape with characteristic breaks will be an Airbus H160 helicopter, which was already introduced in early March, but will not be available until 2018. In conditions where helicopters are increasingly used in the city, the appearance of noise-optimized blades opens the prospect for the creation of relatively quiet aircraft on electric traction.   Related Products :
