Thanks to the online project enornis, everyone can easily assess the potential of your device. Also, moving the sliders back and forth, the scams of the AWE industry are easily understood. It seems that investors do not attract experts at all, or the entire AWE industry has become an object for investment bubbles.
Let’s have a look:
One of the most high-profile projects and, probably, the most expensive. Purchased by GoogleX in 2014.
The company claims that the test sample produces 30kW, but there are ambitions up to 600kW.
Let’s check the project.
The wingspan is 26 m. Why this information is not very clear, but leave the conscience of advertisers. Based on this figure, each screw has an outer diameter of 1.8 m and an internal diameter of 0.45 m
online AWE design shows the following data.
Over Google headquarters, the wind at 10m / s blows at an altitude of 3.5 km. I suppose that the tests are conducted somewhere in another place and at an altitude of about 500 m. But let’s say that they still had 10m / s. Then each propeller produces 390W. A total of 8 pieces, respectively, the energy will be 3.1 kW.
How did they get 30kW? This for each fan is 3750W. This speed is obtained at 25 m / s, or otherwise 50 nodes. Heavy storm.
I fully admit that when falling into a tailspin the plane has a counter flow of 25 m / s. But how much energy is spent to lift the device up again? I think that the total efficiency is 10%, if at all positive.
