Intake Valve and Feliks' ideas

[Holm86]

Would'nt it be better to let the jet exhaust exit further out the circle?? Nearer the tips of the blade??

Then it would need less energy to turn the blade right??

No Exactly. after I explained that as it is the end of the blade mount these outlets, it turns these very slender blade, which introduces them to an extremely dangerous vibrations, preventing restful flight. Besides, most of the energy would be lost in a very long thin hole in the middle of the blade. So with a total that is not profitable, despite its larger radius. But here safety is a priority and not efficiency. Such " supposedly efficient " has been....

Are those jet engines on the ends of rotor blades??
I think you would struggle to lubricate them

[Anth]

Also, I guess the engines would be sucking quite a bit of exhaust gasses in, instead of fresh air

In the 50 theses similar already done. of hard and even had the gear, not have . But it was not a very safe (vibration propeller blades ). for my Heron Apache, also without a gearbox, but it is completely safe. Prop blades are the same as in the best designs helicopters. But the gear no longer needed....

No the Rotordyne had a gas-driven rotor, like your design. The Eurocopter has a jet engine driving the rotor through a free turbine & gearbox so the main rotor creates torque that the lateral props have to counteract. So at zero speed one prop is blowing air backwards and the other forwards. As the chopper speeds up, the thrust differential between them decreases and no doubt at some point both props are pushing the chopper forwards, though there would still need to be a net thrust differential.

Thanks for the many substantive comments. Sure, and this design will require a few more problems to solve, which in practice can only be....

Here are a few solutions that can some of the problems to solve..

Surely you will need to test them in practice, before se makes the right decisions as to the shape of the structure of the drive.
Perhaps such a solution with a single tube might be the most efficient, because it will most laminar flow



Or a Cutter Heron



Of course, a whole can be properly enclosed guard areodynamic...




Well, here an example, if the electric drive can also adapt to the helicopter. Turbine itself would be inside the helicopter, but it would not be permanently linked to the rotor, so that no torque moved...

Ok, ok , but why write " is invented by a German scientist."????

And you do not need to share the head of the block, because the valves go up and not down.

I was with my friends in the Museum of aviation again. "I'd like him to show this demo in which the effect of the vacuum State at the top of the wings, which blows the wind from the fan, the ball is sucked in by a transparent tube

provided in the middle of the wings and a peg that pops up on the wing.

Doing this experience again, so your friend can see it, I am surprised that the ball a is NOT sucked in tube!!

It is that this experience has been vandalized, and the ball is sucked on

Vandalized based on this, with a transparent tube to the bottom was several times the seeds.

But this was not the reason for the lack of vacuum in the tube.
After arrives home, thoroughly by looking at the about the well running the show.

http://www.youtube.com/watch?v=Fb8IFfnb ... r_embedded

I noticed that the tube on the film extends over the upper surface of the wings have 70 mm
The vandalizet show the tube was brought down to equality with the upper surface of the wing.
And this was the main reason for the lack of vacuum in the tube !
Simply air her upper surface of the wing, when it encounters a simple hole in the wing, just get it and seeking to keep the pipes, eliminates any vacuum in it.!!

That is, that the ball could be the suck by the vacuum arising at the top of the wings, in this case the pipe must extend over the upper surface of the wing by about 70 mm !!!

When this tube does not extend, this does not transmit its down this vacuum, even in the smallest degree.

Why is this, explain the following drawings:










Yes so we are one of the one cases where due to vandalism, we fully the specificities of of the Red Baron Windmill...

According to estimates, the surface of the wing of a 100 m square, with a wind speed of 30 km\/h can produce approximately 750 KG lift.
To get 100 KG of thrust of the propeller to the ultralight trike, the engine must have a power of about 50 KW
You can take also denied that the 100 KG over da US 50 KW electrical Dynamo.
Which had managed to seize the entire lift such 100 m ^ 2 wings which is 750 KG, a power Dynamo would be 300 KW.

The Windmill of the Red Baron 100 m x 30 m = 3000 m ^ 2 and this will give us the 9000 KW.

Now you can build 10 such wings one above with which 30000 m ^ 2 = 90 MW.

No and now depends on how many% of this theoretical power we capture this lift and exchange it into electrical current.

And in the meantime since the formation of the ideas, changes a lot. For example, go beyond the "magic circle of the cylinder" was the hardest thing.
When I discovered it, a new type of timing, was the new 4 stroke engine:

Can have two times less cubic capacity, because that is two times smaller turnover at the flywheel.

I think the era of steam comes to an end. At most in obsolete nuclear power plants will be still used.

Half supports the engine has one very big advantage. Piston not friction on the walls of the "cylinder""Only the seals frictions cylinder

Thanks to these properties, the engine may be running on ... the coal dust.
Rudolf Diesel's first engine was built just on the coal dust, but unfortunately zacierał is at work. In the case of half rotate, will not look any login problems.Simply does not have any large surface friction








Only the directory should be chosen for personal seal. Each round you can straighten lines, of course, resistant to coal dust.....
