Right now wind is leading the renewable energy surge and records for the largest turbines are being set. Just how big is the largest one? Siemens is creating a single blade that is 225 feet long, basically as wide as a 747 airplane 다운로드.
Siemens manufactures the mammoth B75 blades in one, smooth, streamlined piece — with no joints — using its IntegralBlade process 다운로드. The technique — which requires glass fibre-reinforced epoxy resin and balsa wood to be cast in a mould — renders the blades steadfast and less likely to develop faults while being beaten with 181 tonnes of air energy every second, when wind speeds are ten metres per second (30 mph) 다운로드. The huge strain it is put under means no blade can leave the factory without being carefully inspected for even minor cracks.
The size of these things is almost unimaginable, like trying to picture three 747’s spinning around a massive pole Twrp download. They will also have to shoot up into the sky several hundred meters.
According to Siemens, when fully constructed this mammoth would generate 6-megwatt’s, while another group is looking into 20-megawatt versions 다운로드!
Chip Yates does not like sitting still. Just a day after piloting his electric-powered Long EZ airplane to over 200 miles per hour – making him the fastest electric-airplane pilot in the world – he had to disassemble the airplane, pack it up and drive 2,000 miles east to Oshkosh, Wisconsin 리얼 스틸 apk. Here at Airventure, Yates continues to be busy answering questions about his record-setting run. And perhaps one of the more surprising answers is that Yates is a not a veteran test pilot 다운로드. He just got his license in June and has about 58 hours of experience, including the record-setting run last week.
When the electric vehicle pioneer bought the used airplane it had a 118 horsepower, four-cylinder gasoline-powered engine that is fairly standard for a Long EZ 다운로드. Over the course of several months Yates and his team pulled the four-cylinder engine out of the Long EZ. They then pulled the 193 kW (258 hp), liquid cooled electric motor out of his record setting battery powered motorcycle and mounted it to the back of the Long EZ realtek HD 오디오 관리자.
With the very well used (Yates calls it “abused”) lithium polymer battery back from the motorcycle in the back seat, the Long EZ was being prepared as a test bed for some of the technologies Yates needs to develop for his transatlantic flight다운로드. But after setting speed records for an electric motorcycle, first up for the Long EZ was a speed run.
Right here, on this blog I share everything about my crazy plan to build my own wings 리눅스 ftp 파일. My goal? To fly with it! Something Leonardo DaVinci, my grandfather and I dreamed of for a long time. But this summer I decided to really start building it 다운로드.
There was some discussion about the authenticity of this video, but the MythBusters team tackled that:
The video of Jarno Smeets’ flight is cool, and I don’t see evidence that it was faked 다운로드. It seems reasonable to accomplish, and is something I have wanted to try for a long time.
The still photos of the parts on a table are helpful and the components are appropriate to what the item does in the air 하나뿐인 사람 다운로드. The motors are rare earth magnet low RPM, high torque, outrunners that look in the neighborhood of 3000 watts or so each. So you could have an output of just under 10hp there 다운로드. The speed controllers look to be appropriate to those motors, and the batteries are lithium ion. This is all appropriate…
