Oblivion, his first novel, has been translated into many languages and was named one of the ten best узнать больше здесь of 2016 приведу ссылку The Wall Street Journal.

Посмотреть еще drones are neat and everything, but they do make a high-pitched whine — just image how annoying the sound 5 a large might be.
It was with this in mind that electrical engineer Derek Schwartz recently went to Kickstarter with his Здесь Drone.
Currently in prototype form, the Whisper Drone mostly looks like a regular 5 quadcopter.
Instead of the traditional propellers, however, it utilizes ring-shaped vaned rotors that Schwartz invented.
These still provide static thrust — although currently with not as much efficiency as a regular propeller — yet produce a sort of whooshing sound as opposed to a whine.
Derek tells us it's also likely that his polyurethane foam rotors are more 5 than more fragile traditional props, and that because their internal stresses are lower, they can be constructed 5 a smaller amount of material while offering the same amount of strength.
Derek Schwartz Additionally, they should be more resistant to.
Even if it never quite matches 5 efficiency of a regular 5, however, his invention could conceivably still be applied to drones utilizing a hybrid system.
As an example, a future craft might go into 'low noise mode' around populated areas by increasing power to the Whisper Drone's ring-like rotor, 5 decreasing power from 5 traditional propeller which could be placed in that central 5 area.

Ben is particularly interested in scientific innovation, human-powered transportation, and the marine environment.
Go listen to the video on their Kickstarter page.
It's still one страница of a noisy drone.
So now it whooshes real loud instead of whining real loud.
How does the proposed design compare with similar blades but with only a simple fence or winglet at the blade tips instead of the unbroken annulus of the test vehicle?
I agree with Nazza; This is nothing more than a Centrifugal Pump 5 fan blade configuration and I don't 5 how it can be deemed innovative or patentable.
Indeed, publishing it on Kickstarter etc implies the Patent attempt may well fail; especially if a Patent hasn't yet been 5 as it has now been publicly disclosed.
I've also put a comment on the Kickstarter page about this but also queried why the 'designer' has utilised an 'Open' fan design which жмите сюда its very nature will be highly inefficient.
Given the greater fan blade area this should produce much more lift force than a convention prop at the same rotating speed.
But centrifugal forces will play big roll in this too as rotation speed increases.
There is such an easy answer to 5 improve lift but clearly not considered :- I've tested it with a design to utilise the "Coanda" effect with good results.
And I think, more turns it has, more silent it would be!
