Sep 30, 2011, 06:35 AM Registered User Thread OP Well, maybe but the full electric version: These eight electric motors: http://shop.rc-electric-jets.com/RC-...DF120-1A83.htm 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 Bumblebee Andrew I have no problems with leaking oil... Last edited by Feliks; Oct 01, 2011 at 06:23 AM.

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.

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

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

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.

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...

Seems to me that the project Herons Apache version "FEL -X" will not have these disadvantages, and will be missing heavy and very unreliable gear.... Andrew
 Oct 17, 2011, 07:01 AM Registered User Thread OP 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... It is air- gear drive Andrew

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.....
