RE: 4 Stroke Redesigned

So is there a working engine yet or has this project died? Don't see much about engines in the last couple of pages and can't be bothered trawling through the
rest.
You should do a special program for such a Cad engine four stroke, because its proper design is very difficult. But then the operation will take and a lot of satisfactionrest.

Old ideas in new study:
This gear drive in a helicopter that is bothering me. Another way to get rid of her. By the way, turned out that the rear propeller and also you can get rid of , because the helicopter does not have the torque of the main propeller.
The helicopter had already been built. But it had drawbacks: no, for example, could not take full advantage of autorotation, because the propeller with a hole through the center did not have good aerodynamic properties....
http://en.wikipedia.org/wiki/Sud-Ouest_Djinn
http://en.wikipedia.org/wiki/File:Helicopter_Djinn...
I missed this problem and the propeller is as it is most optimal.
Also today after assuming control of the helicopter adjustable nozzle (vectoring nozzle) on the outlet gases from the turbine driven, will be very precise.

http://upload.wikimedia.org/wikipedia/commons/0/0e...
In summary the lack of a gear transmission and rear propeller helicopter will certainly reduce weight.

If you do not want to lose a large diameter fan operating in the Venturi nozzle, you should use " internal Venturi nozzles ".
These are just two cones inside a circular tube
Their convergence must be in accordance with the Bernoulli's principle, just like a normal venturi nozzle. So must be kept laminar flow. But we gain a large diameter fan. Theoretically, the energy gain obtained is 10 times larger in relation to the windmill in a narrow place of the normal venturi nozzle....
Field cross-sections must be changed in the same function as in classical venturi

Wind and water have long been a very liked.
So I think that such a solution, consistent with their preferences, will be most effective
It is a Venturi vidmil that drives large enough vane pump with sealing ring via water.
Thanks to such a seal, which is not consumed, and it is tight, you can use all the energy that gives us a venturi nozzle of the vacuum produced.. Because the turbine does not have any leaks. So ,theoretically, this will be the most efficient use of wind...
We can thus take advantage of the vacuum energy, what we get in other ways to obtain it from the wind.

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_experimental_ultraligh...
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....

Well, maybe but the full electric version:
These eight electric motors:
http://shop.rc-electric-jets.com/RC-Lander-DPS-120...
Now just: 8 electric motors, ie 2 3 / 4 Lbs (1,35 kg) each battery X 8 pieces = 22Lbs (~ 10 kg) and can fly for 5 minutes. That is 132 lbs ( 66kg ) meringue can fly 30 minutes at full load... Weight of motors is 132 +16 = 148 lbs (74 kg) fuel + engines.
http://alshobbies.com/shop/lookupstock.php?pc=7178
Weight of the traditional system of propulsion engine of CRE MZ202 is 38 kg, the transmission of about 15 kg, 5 gallons of fuel to the tank about 20 kg, the total weight of 72 kg and the propulsion flight time 1 hour..
When you subtract the tail rotor 20 kg to obtain also a similar range..
Until you can control the direction of these one additional electric motors, administer, only a little smaller.
And this looks like a traditional electric version of the aircraft

Bit of a daft question here, but could these kind of fans actually be used as eletric superchargers? they look powerfull enough / to shift enough air. maybe just use the to help spool a turbo? you could mmaybe mount one in the intake to the trubo (do they do them over 100mm??) then once the turbo it up to speed it can be shut off?.........
I know there is CRAP PC fans that are sold as these for about £100 but these look more like the real deal!

I think that also the propeller airplanes can replenish the idea of Heron's Jet Propeller. The latest toy modelers have superior features, and you may use them for "big air ".
Well let us take a small aircraft engine Rotax 447 to 44 Nm of torque. On the axis of the propeller must gear, have twice as large, ie ~ ~ 100 Nm (10 kgm ). Przytakim driving the propeller with a diameter of 1700 mm will be to spin it properly and give the appropriate string.
So at the end of a single turbine on the arm of Heron 's say a length of 500 mm have a string 200N (20 kg), and two shoulders at 100 N (10 kg). Then we were given the same torque on the propeller, which gives the Rotax engine.
http://www.faston.home.pl/r447.htm
After putting two turbines, modeling of over 10 kg (100 N), we get a replacement Rotax engine.
They even have the parameters several times larger than we need for this example.
Well, the weight of the drive unit will be cheaper too many times, what in aviation is crucial
It turns out that we already have a fairly large selection of gas turbine engines such
http://www.jetcatusa.com/p200.html
http://www.amtjets.com/Titan.php
And of course we have also quite a large number of electric motors to drive the turbines of jet aircraft models, whose parameters are such that we can use them in Heron's propeller well. Their parameters and parameters of the battery used in development Propeller Heron, causes them to become competitive with conventional engines
http://shop.rc-electric-jets.com/RC-Lander-DPS-120...
They can be used in this exemplary model propeller Heron
After viewing a few videos of models turbuny aircraft, I saw that these turbines do not have to be at the end of the model, and may be in the middle, and the aid of additional exhaust pipes just flies out of the model.
http://www.youtube.com/watch?v=TNP9TbkYCrw&fea...
From this reason, and my solution also applied this collective pipe, which is separated into 4 and changes the direction of exhaust gas.
Thanks to this, quite seriously improves the design Propellers Heron....
And weight in relation to the Rotax is 10 times less...
So that is similar in other much larger propeller propulsion system also...
