Drones –<\/strong> Pesquisadores da Universidade Johns Hopkins, nos Estados Unidos, encontraram inspira\u00e7\u00e3o em um esbo\u00e7o de Leonardo da Vinci<\/a> do s\u00e9culo XV para desenvolver drones que produzem menos ru\u00eddo. A inven\u00e7\u00e3o, conhecida como \u201cparafuso a\u00e9reo\u201d, consistia em uma h\u00e9lice em formato de espiral, feita originalmente com juncos, linho e arame, e deveria ser girada por quatro homens em uma plataforma central.<\/p>\n

Da Vinci acreditava que o movimento de rota\u00e7\u00e3o dessa h\u00e9lice criaria for\u00e7a de sustenta\u00e7\u00e3o suficiente para permitir o voo. S\u00e9culos depois, cientistas recorreram ao desenho para pensar em solu\u00e7\u00f5es tecnol\u00f3gicas que pudessem tornar os drones mais silenciosos.<\/p>\n

LEIA: V\u00edtimas de tr\u00e1fico humano s\u00e3o exploradas em \u2018f\u00e1bricas\u2019 de golpes digitais, alerta Interpol<\/strong><\/a><\/p>\n

Os pesquisadores recriaram o projeto em 3D com base nos desenhos originais e simularam o comportamento do ar em torno do rotor enquanto o drone pairava. Os testes demonstraram que o design espiralado espalha os redemoinhos de ar que se formam nas pontas das h\u00e9lices, reduzindo o zumbido caracter\u00edstico desses aparelhos.<\/p>\n

Segundo os cientistas, o novo formato mostrou ser menos eficiente em termos de aerodin\u00e2mica, mas pode ser \u00fatil em situa\u00e7\u00f5es em que o sil\u00eancio \u00e9 mais importante do que a velocidade. A expectativa \u00e9 que a tecnologia seja aplicada em drones usados para entregas urbanas, fotografia a\u00e9rea e miss\u00f5es de resgate, reduzindo o inc\u00f4modo para quem vive nas \u00e1reas sobrevoadas.<\/p>\n
