Forever Electric car ( by wind force generator) - YouTube


But how do you replace the propeller, such as my amplifier, it obviously will not be quite as much as the delightful film ... get it right?
Certainly amplifier and give more energy propeller.

Yes, this dinner is certainly a lot cheaper ... It's just a matter of when the price will be less than zero....

One part of the reply to "when", is for example the case of such a drag, "windmill". Under normal conditions, standing statically on the ground windmill his case at all practically drag, we do not care, because we have any number of fan blowing on the wind. And now the resistance front, as will be larger, only the rigidity of its mounting must also be greater. Practically the value of the resistance front, even if it is larger, a large amount of available free of wind, makes no need to worry, we have the resistance front .... But from the moment when the "wind", we begin to produce, for example, an electric motor car, it is known that the resistance front "fans" will have a major impact on the amount of electricity needed to maintain a speed of "wind" (car). . Know that the windmill of "hole in the middle" will have less resistance. and even the shape of the hole to be similar to the airfoil wing, his leading the resistance may be at the level of resistance of this air wing and have even just 10% of the resistance of a flat plate, with the same profile section ... If it is only 10% of the and the amount of energy required to achieve this speed "wind" (car) will also be at the level of 10% of the energy needed to overcome the resistance of a planar face. So that is one of the first steps to reduce our price lunch, is the study of our "fan" in the wind tunnel in terms of the reduction of the resistance front, just what it is in their cars and their coefficient Cx

Here, such a "small fan", which Viggen fighter driven by a small propeller emergency hydraulic pump to control the plane, in the case of loss of the main hydraulic system.

You can see that at higher speeds, the propeller can be very small ..



As you can see the propeller drive in serious applications
So may be small and of recognition, a lot of power to control such a large fighter, because at higher speeds the propeller is more efficient. Its efficiency according to the speed increases up to the third power in the dependency ..

right on the apron in front of the hangar, and yet it was the Museum of Aviation, I played my models on a Wire ... I made ​​a nice deck Tarpan plane ... Sorry did not start, bi was too small only 2.5 cc engine and was required 5 cc .. but this did not have .. I could only dream of ..

[QUOTE=vwgtiIII;81991698]If you had even a basic understanding of engineering, you wouldn't feel that way.

Feliks has the sort of naive ideas that "environmentalists" have when they make sweeping generalizations about how doing X will save the world.

These designs are hair brained and outlandish, at best, with very little utility in the real world.

That small prop on the airplane is a small generator that powers the hydraulic and navigation software. Yes, when you are flying 500mph, you can generate 10hp by coasting. You WILL NOT power an entire city with the same principle and a 1' dia prop unless you are traveling at the speed of light.

I would LOVE to see some actual calculations. Math is math. Anyone with math skills should be able to read and interpret his calcs. Post those and I'll give him some credit. Until then, this guy is yelling the bible aloud from the street corner.[/QUOTE]



All right, we'll use the math ...
At the beginning of your data correct some of the aircraft speed. If it is to be an emergency control of the airplane, that's for sure, it must be to enable the load, ie the propeller must give sufficient power, as you have specified about 10 HP power control ... It's just that the aircraft lands at a speed of 220 km / h, and it must work perfectly yet. Propeller has a diameter of about 30 cm.

part no 9 :
http://www.temporal.com.au/viggen_final.pdf


Well now using venturi calculator, count the venturi nozzle, which is in its narrowest point is 300 mm, so that the propeller be able to run when inserted into it. As you have specified, at the speed of 220 km / h it will give the 10 Hp.
I asked to facilitate the original input parameter of the nozzle diameter to 1000 mm (1m). her throat identified on the 300 mm. There's a quiet propeller would seem to shoot ... Here are the results of this calculator venturi ... input speed is 25km / h and the speed of the throat is 284 km / h, which is significantly more than the 220 km / h landing ... So we should calmly from the propeller to obtain these 10 Hp power ....











Now you should do such an experience (or as you have enough imagination you can not do): You have to cut out some plywood, or flat plates made of plastic, and cut out the circle with a diameter of 1000 mm (1m). So cut the wheel, you have to fasten themselves to the chest or his back. It should then get on the bike, and try to accomplish this on a bicycle pedaling speed of 25 km / h. I think it lets you easily measure .. A man riding a bicycle is not achieved by 1 Hp ... but quietly get this rate, the pinned wheel with a diameter of 1 m.
This wheel has the same, or even greater air resistance as a venturi nozzle with a diameter of 1 meter original input. But this gives us the nozzle throat, as he You noted about 10 Hp, because in the throat, the air flows at a rate ~ 10 times greater than the speed of Input, or 280 km / h.,
And the propeller can give us the 10 HP. It is 10 times more than we can give strength to propel the bike with the circular wheel strapped to us. I think that in order to achieve a speed of 25 km / h, we do not need more than 300 watts .... So, if the bike mount the front section of the nozzle 1000 mm, it will get the 10 Hp in her throat on the propeller and drive the bike with the nozzle to a speed of 25 km / h, we only need 300 watts ..


I think the only thing I have left is to wait for your points ...

Here, the first aircraft with Ram air turbine. Its ME-163 Komet:



And here the story framework:

stuff here alternators produce. At the same time, such as is sufficient to drive the the bicycle. It gives as much power as the guy who races

Now matching jets such dimensions alternator, it will have the characteristics needed to drive the bike (and other vehicles as well).It will have only 600 mm outer diameter ..






If the resistance front will be much smaller than the flat full circle. In laminar flow, may have only 15% of the value of such a flat resistance, as it has air wing profile....

[Feliks]

And here's a rat, even now encased pipe .. Just make cones .. Aero Albaros plane.





This is a photo of a helicopter engine 400 hp in comparison to my hand. For this engine, only air flows, and its mass generates the power to the motor shaft. Mass of fuel burned is negligible .. If, for example, in a wind tunnel, we will do the same movement entrusted by this engine, as during normal operation in a helicopter, you will be given a power take also the same power. 1 KG air flow gives us the 100 Hp engine PTO shaft ..




I would like to remind my project, called the internal Venturi nozzle. Taking the ratio of change in cross-sectional area, we obtain a nozzle, which has a maximum diameter of the turbine and thus gives the maximum torque greater than the traditional nozzle.

[QUOTE=jetman150;11124380]I've got a bit of fiberglass and pvc pipe ine the garage.. What dimensions of venturi would I need to have, for a "windmill" electric generator, if the average windspeed in my area is 10-15 mph?[/QUOTE]

No thank you, finally, for a very specific question. Because of this specific not yet had my manual is not yet complete. But a few important tips I can already provide, for a good while I'm thinking about it already....




First units 10 and 15 miles is 16 km / h - 24 km / h or 4.5 m / s to 6.75 m / s

Now I think that should do the nozzle of the same size and calculations as in my post # May 29 2013.

Now this: the witrze 15 miles in the throat nozzle of dimensions we will have theoretical speed 167 miles (270 km / h) .. the valve on the power of the fan is due at the speed we can get even theoretically about 20 Hp


to get the power from the electric generator, you must already quite large in size,. I could barely fit for him to die in his throat. and it completely obscured. It must therefore be outside the nozzle and be driven by a toothed belt from the propeller., and this is the biggest problem.



Same cones and these dimensions can all be done the hard styrofoam by cutting the thermal cutting CNC polystyrene. Most important thing is that the external surface of the cone must be round, full, of the 1000 mm dimension. Theses external surface of the throat must have the dimension. So that the air nozzle was skipping necessarily the way to the straight line, otherwise may not have a good performance at all. All these figures are just patterns of cones. The figure pointed to the red line is the nozzle look like on the outside.




Why is it important to air bypassing the nozzle on the outside was the shortest path in a straight line? not because I'm imagining that the venturi nozzle is so very close to collapse like a normal airplane wing over and over. its aerodynamics will surely like this over and over again folded wings. wing and best for low speed is the lower edge of a straight line. here shown theoretically how to wrap the wing sites. Now Lifting force of this wing will also "wrapped" inside, creating a negative pressure in the whole nozzle .....



It's a rough ..

I believe you have Solidworks.

Do you have simulation? I suggest that you test your venturi tube in simulation, and see how the flow works, and how the airflow inside the initial parallel part of the tube does not match the freestream air.
[/quote]

Unfortunately, I was no longer Solidworks for some time .. I Personal Edition 2004, but this version does not support more ... I tried to run a demo in 2012 but received three different serial numbers SW unfortunately no accepted ...
Even so, I'm thinking that the simulation nothing new has been brought to. There is one question that should be answered. Is there an amplifier, which amplifies, without any energy supply from the outside ...
Obviously it is.

http://en.wikipedia.org/wiki/Phonograph

Edison applied it to his phonograph. Without a large conical tubes, the phonograph mined only very difficult to hear the sound. after adding the tube pfonograf game quite loud. So there is an amplifier that amplifies, without any external energy supply. Exactly in the same way all the wind instruments amplify sound mouthpiece. Despite the mouthpiece is similar in all instruments, they are depending on the size of reinforcing a particular frequency, the bass tuba to the trumpet. So we have the next examples amplifiers without additional energy from the outside ....
We just reinforces the venturi nozzle, and is arguably, even though it may be one like it, while others are not ..
Also the plane, which is heavier than air can fly, when his wings around a laminar flow. When the parameters are come forth out of the possible formation of his lack causes that the plane drops like a stone to the ground .. Certainly anyone experienced this building a variety of model airplanes, some of which would not fly ... So you need some piety that everything went well.

Therefore, teeth sprite is activated, the air speed gain amplifier in the venturi, laminar flow to keep it. There should be understood that a laminar flow can not have a strong whirled air. An excellent example is a laminar flow in a plane that has the wings of the propeller engines. . Spite of strong turbulence behind the propeller, wing has a laminar flow conditions and wing create lift for the aircraft.

Also in the venturi nozzle, air turbulence on the turbine dynamo driven machine located in the throat nozzle will cause no disturbance of laminar flow resulting from Bernoulli's law

Anyway venturi nozzle is amplified wind speed, without any energy supply from outside.

Well, this a lunatic continuing science, here's the project added to the venturi such an aircraft for flight litte 300 watts of power. Drew a venturi nozzle such as for example for driving a bicycle. I tried to accurately maintain scale drawings and nozzle. The nozzle has a dimension of 600 mm diameter and 2500 mm in length, and should be according to the calculations give the 300 watt ...

You will agree with me that it does not look unreal :rolleyes:

Maybe that so few students on this board bought the plane, which is just an old record and added the venturi nozzles, so to show that they can, .. and That Daedalus so he could follow the sun all the time to follow .. without excessive risk of his strength or the fuel runs out ...

[quote name='Kelpiecross' post='6313921' date='Jun 13 2013, 11:26']Feliks - maybe you should make a helicopter version - a venturi/RAT assembly on each rotor tip with the electricity generated driving the main rotor motor. The faster the rotor spins - the more power is generated by the venturi/RAT assemblies causing the main rotor to spin ever faster - and so on. You would have to be careful the rotor didn't overspeed - but it's a bloody good idea.[/quote]

You know, I also like the idea .. But is the propeller helicopter vibrations will not fall as a result of the weights on the ends of the propeller? But the speed would be staggering ..

A few houses here do for a small power plant ..
