Discussion:
AS332 L2: Main and tail rotor with Yasim

Hello YASIM-Rotor-Profis

Some weeks ago I started a model of an Aerospatiale AS332-L2. Now I
tried to configure the main and tail rotor in the FDM. I was reading the
README.yasim from CVS carefully but I do not understand some parts of
calculating the rotors.

I collected a lot of information needed (like NACA airfoil definition
etc.) but I still can not do some of the calculations. Can someone help
me calculating some of the yasim props for the rotors? I can send a list
of props I miss and also any technical data I collected.

Another question is how to configure the rotorgear right with two
engines and how to set the h- and v-stab correctly.

Is someone interested to help me making this as332?

Thank you!

Just send them to me.

Up to know the rotorgear does not support proper simulation of engines.
You can just define the maximum torque of the engine (by defining the
power). For a better engine simulation you need to simulate it with a
nasal script, which calculates the maximum torque the engine can produce
at the actual rpm. Or, by setting the target rpm of the rotorgear to a
value higher than the real target (to overrule the rotorgear governor),
you can calculate the actual torque of the engine with nasal and
simulate a governor within nasal or let the pilot doing this.

yes, me ;-)

Hi,
I can be sure that the Super Puma will be in swiss colors, or? (and there is hopefully a multiple liveries over mp-system?)

In the moment the Bo105 simulates two engines best, and it even simulates blade vortex (not ring vortex state) so you have the the typical rattle at certain situations like in real. So much In know, FGFS is there even better than MSFS and X-Plane. So it is worth to look at the bo105.nas for the Super Puma!

There will be one livery from me and hopefully in the future a lot of
liveries from others ...

Thanks for all your answers. I was having a closer look into the
structure of Bo105 and I decided to change my starting point. Bo105 is
done very well and I will take it as base for my further work on as332.
Actually I am cleaning up the model. Then I will do some instruments
again and after its I will come back here with my questions about
yasim-props. Or I will send all the data to Maik - maybe one of the best
ways to get this Superpuma flying ;-)

Yep- the bo105 is made great- though I fear that the main author is gone...:?:
a good starting point for all two-engines helicopter!

I'm sure Maik can't wait for all the datas for making a good fdm, so you should have enough time for making the 3d-work.

Who can't wait for another helicopter to fly

Nope, still here and working on the bo105. (I just won't assist
in the planned degradation of the property system, so I won't be
working on general code for the time being.)

Fine to hear- do we get this feature from the PAH as well some day? :http://www.flugzeugforum.de/forum/showpost.php?p=1115796&postcount=5 and http://www.flugzeugforum.de/forum/showpost.php?p=1131883&postcount=6

Wasn't on my TODO list, but sure. It has rather low priority, though,
as the missiles are very unrealistic. They aren't propelled and not
steerable, so you won't hit anything with them, anyway. I could model
them with some nasal, though, rather than via submodel manager.
