Calling Feliks From Krakow

I found an alternative to these seemingly crappy predators.

This is really cool. It's a 4 stroke with no valves and multiple cylinders.

looks heavy to me, heavy valve train also, how many rpms?

Rotations are limited only to the lower parts of the engine that spins twice as fast than góra.Na example, 20 000 RPM down a mountain, only 10 000 RPM. and never will meet...

Weight popped 75 mm 1000 G
weight piston & rod 76.5 mm 850 G
weight popped 62 mm 400 G
weight piston & rod 62 mm 370 G

But the window of the flight of the valve of 75 mm is only 64 mm, what is very similar to the window of the flight piston 62 mm .

That is it results from it that the valve of 75 mm is giving the same flight as the piston 62 mm that is 1000 G to 370 G !!!!!

==~~ 2.5 more weight popped to piston& rod !!

It only looks impossibly. but this way is.

I am corrected

I would have never thought that the valves were heavier than a piston/rod.

That is why he made such a photograph, because most people thought the same..
And the weight of such a valve, was the first thing when you come up with a basic...
The larger dimensions of this difference is greater.

Imagine that you have a valve with a diameter of 500 mm and a height of 1200 mm shank diameter 120 mm... from the ship's engine. Has virtually not to raise yourself... And now imagine an aluminum pot with the same diameter of your mom in the kitchen...
And you understand everything..

And now, maybe a new idea. Can finally go cart can be equipped with a differential.
It works completely without oil, making it easier construction. The need for only a few sealed ball bearings with grease...

[Feliks]

I had a differential in my kart, it eas easy to steer, exept when you took hard turns it spun up the inside wheel. So, i welded it up.

Its harder to turn but i get better traction.

Good ideas!

Ok, but how will design monstrously truck, remember to think about it ...

Another idea, and engine size of 2000 cm ^ 3 such that it is suitable for go-karting...

And it's a two stroke! Kewl.

 

[fowler]

is that a turbo the size of 1/2 my house haning off the side

 

[Feliks]

Proposes a slightly smaller, but it is stronger.
Presumably to make in your garage if you have a fairly large...


And about half rotate.

Star engines were characterized biggest always force density

Below picture of the star half rotate around 10 (40) with "cylinders". for the transparency of the picture one can see only 3 additional "cylinders" more than is at the animated film.
One can also see dimensions of the whole of the engine in the assumption that every cylinder has such dimensions for the picture half rotate with the set connecting rod of the Sulzer D= engine of 900 mm and stroke 2500 mm .

So 10 (40) "cylindrical" engine half rotate about the same working capacity in comparing to the Sulzer 10 engine cylindrical on the picture below .

Sulzer: 10 Cylinders 20 m long , 15 m hight , 1500 Ton weight

Half rotate star : 10(40) "Cylinders" 4,5 m diameter , 4,5 m long
about 70 ton weight.

And most importantly.. Since in the engine half rotate mass innertia are several times Sulzer smaller than in the engine, engine half rotate can work with the much greater rotation speed.
Slzer : 102 RPM 60 000 KW

Half rotate 250 RPM 150 000 KW

In same intake work volume .

Sure the engines of cars will be similar proportions :rolleyes3:

wow same principal except more efficient exhaust removal and air intake... very interesting

 

[Feliks]

At the same time with this problem long ago have learned a very effective remedy.
In this project, yet much more efficient charge exchange takes place because the road is not something that sent the outlet, the outlet valve in the shape of mushroom ( poped )

Here is a device for high efficiency in the exchange of cargo

In addition, the analysis engine, only on the basis of the animation is even in the 10 % not true with respect to its features.
I myself, a prototype builder and contractor, I was wrong about the engine performance up to 2.5 times ( the fortunate in the right direction )
I found it very seriously risking my life, but not even thought that I could foresee that bad...

....... i think ve have a proble.... lol what is that? i got a feeling the valves kissed the piston right?

Yes you are right Mister Twister. A here a few examples of how this joyful creativity usually ends ...

In my design at all occurs not drink the head gasket, because all the cylinders can be made from a single block of metal...

Thanks to the new Heron's Apache we can build a pretty good quality helicopter

When we begin to design a small personal helicopter similar to this:
http://rotorfx.com/mosquito_experim...erimental_ultralight_helicopters_for_sale.htm
We see the need to drive to the main rotor diameter of 18 feet (5.5 meter)
We see the need to drive to the main rotor diameter of 18 feet (5.5 meter) and 540 rpm rotational speeds. To achieve such a speed we could use a torque 800 Nm ( ~ 80 kgm ).
Returning now to the Hero 's Apache, we can assume that the torque on the main propeller tubes produce more than us four propeller.
Let's say that in May they long 3.5 feet (1 meter ). So, as at the end of each of those tubes you put the engine that gives us a sequence of 10 N (2 Lbs) values ??(1kg) it will be added to the rotor torque of 10 Nm (1 kgm)
So four of these tubes with motors will give us a 40 Nm (4 kgm).
Now, assuming that our helicopter will be lighter with a big motor, gears and tail rotor, we can assume that he will need to drive only the main rotor diameter of 600 Nm at, say, 16 feet (4.9 m).
So if we placed the total at the end of the tube Heron's Apache silnki of values ??within 600/40 = 15
15 X 2 lbs = 30 lbs of force within, we get has fully functional helicopter....
As it turns out, these motors have already modelers....

Weight engines 8 Kg (14 Lbs)....

So it happens that good fun can become a good professional...
