Empresa cria aeronave que gasta até 10 vezes menos combustível

Avião mede cerca de 37 pés de comprimento e possui uma envergadura de 52 pés Otto Aviation

A empresa norte-americana Otto Aviation desenvolveu a aeronave Celera 500L que consegue voar em velocidade jato – mais de 740 km/h – com consumo de combustível até 10 vezes menor.

Segundo a empresa, enquanto um jato convencional gasta 11 litros de combustível a cada 3 ou 4 quilômetros, a nova aeronave consegue voar de 28 a 40 quilômetros com o mesmo volume. Os custos de operação também são menores – US$ 328 (R$ 1.801) por hora, contra US$ 2.100 (R$ 11.531) de um jato tradicional. Até o momento, foram feitos 31 testes bem-sucedidos.

O avião tem lugar para seis passageiros, mede cerca de 37 pés de comprimento e possui uma envergadura de 52 pés. Seu design, com fuselagem em formato achatado e asas localizadas na parte traseira, ajuda a manter o que se chama de “fluxo laminar”.

“De um modo geral, o fluxo laminar ocorre quando o ar segue camadas muito suaves e não tende a se misturar entre cada uma dela”, diz o CTO da empresa, David Bogue. O executivo compara esse fenômeno com o que ocorre em um rio quando a água atinge um poste que sustenta uma ponte. “O fluxo laminar é onde a água atravessa suavemente.”

As asas fazem a sustentação acontecer, mas também interrompem o ar suave sobre a fuselagem. A hélice fica atrás pelo mesmo motivo – uma hélice na frente seria hostil para suavizar o fluxo.

“O Celera 500 L é uma combinação de uma estrutura aerodinâmica e um sistema de propulsão muito eficiente”, afirmou o CEO da empresa, Bill Otto Jr. ao portal Popular Science. “O objetivo é ser capaz de voar entre qualquer par de cidades nos Estados Unidos, ao mesmo tempo em que permanece com custo e tempo comparáveis às companhias aéreas comerciais”, completou.

Duke Kahanamoku reflects on surfing, Olympics, and old Hawaii in 1966 interview

Duke Kahanamoku is the most influential surfer of all time and is often hailed as the father of modern surfing. There is nearly no one questioning these titles. Recently, Public Broadcasting Service (PBS) Hawaii unveiled a never-before-seen interview with the legendary surfer and Olympic swimmer. In the 1966 episode of Pau Hana Years, a seminal Hawaii television program that aired on KHET-TV (now PBS Hawaii) for 16 years, running from 1966 until 1982, Bob Barker chats with Duke Kahanamoku, then 76. The conversation drifts from royal ancestry to Olympic lanes, from Hollywood sets to a surfboard shaped by hand, tracing the outline of a life that helped define modern surfing and Hawaii's public image in the 20th century. And if you know little about the man who dreamed of getting surfing into the Olympic Games, this is a precious piece of history. A name with history, worn casually The interview starts with Kahanamoku explaining that "Duke" is not a title but his giv...

The hydrodynamics of surfboard fins

Have you ever wondered why a surfboard fin looks like that? It is a single or a set of fixed blades or keels located under a board, near the tail, often no bigger than a hand. Yet that small surface is where much of the surfboard's behavior takes place. Speed, hold, looseness, and the feeling of control all trace back to how water moves around fins. The physics of surfboard fins falls under hydrodynamics, the study of how fluids behave in motion. So, according to science, they feature a shape designed to turn flowing water into several forces. Let's take a look at what's at stake when fins and water interact. Lift and the feeling of control One of the key variables in hydrodynamic terms involving surfboard fins is lift. When a surfer leans into a turn, the board tilts and the fins meet the water at an angle. The angle is enough to create a pressure difference between the two sides of the fin. Water speeds up on one side and slows on the other. The result is a sidewa...

How paddleboarding transforms your body and mind

Adventure is on our doorstep. With so many different bodies of water available to paddleboarders, from city canals to coastal routes, we can find adventure in places much closer to home than people might initially expect. According to the Canal and River Trust, 50 percent of people in England and Wales live within just eight kilometers of a canal or river, and eight million people live less than one kilometer away. I had lived within just a few kilometers of the Leeds and Liverpool Canal for years and never really explored it before stand-up paddleboarding (SUP) came into my life . The challenge created both a new perspective and a deeper love for where I lived and the areas which I passed through. On my coast-to-coast journey, I slept in my own bed for two nights as the route passed through my then hometown of Skipton, yet I felt I was on a grand journey of discovery. We are braver, stronger, and more resilient than we think. SUP not only helps us feel more connected to our va...
