Good evening Cuicui!

It seems a bit fair as power in the first video but on the second video the guy even allows himself to make magnifying glasses. it is certain that the weight / power ratio is very high but too bad it is very noisy because the price of these engine / turbine is very accessible since they come from reduced models.

There is also a twin-jet version of the Cricri, but I can't find the video anymore. It consumes a lot!

Hello

A psychopath who defends another psychopath.

Nothing special.

It's stronger than you 11 posts today there are two missing to get your daily ration.
Rotting post we talk about TURBINE here and if you know something in this area speak in we listen to you.
I want to learn about the turbo prop and about airplanes that interest me a lot (not pasted copies of wikipedia but if possible of the experience lived)

You really don't need me for that, you can do it all by yourself:

Before Mr I know everything looking for butts

And in the one above, it wasn't me.

It doesn't remind you of anything, your dirty hypocrite game:

Where did you see a henchman with a kalash who was there to prevent you from posting here? Wouldn't you be a bit paranoid ???

So mingle with your onions and you'll see how much better it will get. Because if there’s just one or two that cause trouble forum. You're a fan club, seen!

And to say that I encouraged you to come back here. I would have done better to be quiet than to worry about an individual with sometimes asocial behavior.

PS: I am leaving this thread, but you have been warned. You spoil my posts and I make a remark in yours.

For the moment I have a remark against 40 of your rots!

There is some margin: with good word, hello.

Another rotting subject on your part!


Obamot you want me to resort to the discussions in PM that we had you and me when you wanted to leave the forum?

You are serious and you are unable to realize that you are the problem here and that it is not the others, your last comments demonstrate a problem between your two ears and only you can remedy it, you take the mouth with everything the world and you ignore all the little messages that everyone wants to pass you staying polite with you but instead you always push the problem on the others!


I tried to help you by warning you without success and that's where we are!


Go get treatment!

André Good evening!


I found this still in the prototype stage as a turbo propeller:

It is not designed with air bearings but still has the merit of being used on a light aircraft.

There is also from the same manufacturer this reactor with 1200 n:

There is also this one smaller from Jetcat:

There is in u more powerful on the German site!

Hello

Amen everything has been said

And to say that I encouraged you to come back here. I would have done better to be quiet than to worry about an individual with sometimes asocial behavior.
As if André needed your help go to the forum ..
Calm down, analyze and check if on someone else forum you do not have the same problem, and also in your entourage, if there is not an alarm that lights up ..
(End of the off topic, before I let myself be led on a ground where there is nothing to learn.)

Let's come back to the subject of turbine propulsion which is much more interesting.

For the video of the paraglider with turbine, the big defect of this propulsion is that at low speed notably acceleration very poor performance, the same problem on the CRICRI with two turbines. there is also the question of efficiency the smaller the turbines the more difficult it is to improve its efficiency even with exchangers.
If in aviation we prefer to use turboprop it is mainly for reasons of longevity of the turbine versus a piston engine the lower cost on maintenance, longevity a piston engine does not often its potential which rarely exceeds 2000 hours, we prefer to sacrifice on consumption for the benefit of safety. Although on the turboprop the reducer is the failble mailon in particular the first gear which have very high speed for small turbines, and the type of oil and the bearing must be of high quality.
Even in the choice of propellers on piston engine aircraft it is a compromise between RPM and diameter.
A small propeller that rotates quickly is similar to a low accelleration turbine bad rate of climb plane difficult to pilot under full load (the only advantage low drag on cruise)
but plane pleasant to pilot see dangerous on small tracks or obstacle or in mountain
A large diameter propeller gives good acceleration, a rate of climb and a capacity to carry more load, despite a loss on cruising speed and also too noisy.
We have the perfect example on a Cessna 150 engine 100hp propeller too small aircraft with poor performance.

Ah yes, there are some who have short memories!

We must salute the return of André, who had made us sad when leaving.

You did not leave the forum perhaps? And I was not there to have done everything to dissuade you from it? Although you were tackling each other?

And at the time, even if I defended Alain G, that you had managed to get out of its hinges (Alain G also has a short memory !!!)

I also took your defense:

It would be better to start "trusting humans" again! As André suggested. (And yes !!!)

What a bad language you have! And you always bring out the same verse. But before playing the game of hot potato, there is no point in lying and you have to have proof of what you are saying. Should we still fear you ...
