Re: [Flightgear-devel] Re: I am new here/ helicopter flight model

[Maik Justus]

Hi Carsten,

oh, I am not so good in writing lines, which explain how to fly a heli. 
And in detail, I only know how to fly a model helicopter. But you can 
find a very detailed explanation written by a "real" helicopter pilot at

http://www.cybercom.net/~copters/

Hi Maik,
I know it's a little early for my question, but I am writing a FG
Flying Tutorial and want to add a chapter about heli flying.
Would you mind sending me a couple of lines describing how to handle a
heli? The only information I got, is the FLY II manual and I do not
know, how good it is.
TIA,
Carsten

Hello Erik,

I tried to add animation for separate blades, but I
failed. (The 
animation file seemed to me that it is possible,
but...).

The helicopter model is working, but I am still
debugging. I use two 
different approaches, one more analytical and one more
numerical, and my 
aim is, that both result in (nearly) the same flight
behavior. Up to 
now, they differ in some details, more than I can
understand. And I 
don't know which approach is wrong, maybe both.

And some garbage collection on the source and some
documentation is 
missing...

Some other details are missing, but they are not
necessary for the first 
version.

Hi Melchior,

meanwhile I am using your bo to fly with fg, but I
       

have a problem. My 
   

flight model puts out the flapping angle and the
       

incidence angle for 
   

every blade, so I wanted to animate the 4 blades
       

separately. But if i 
   

rotate a blade separately ("blatt1" .... "blatt4"), I
       

see no rotating 
   

in the 3D view. If I rotate "rotor", the complete
       

rotor (incl. 
   

blades) is rotated. I supposed the "blatt1"..."blatt4"
       

to be the 
   

blades and "rotor" to be the rotor head, but it seems,
       

that "rotor" 
   

is the complete rotor; but what are
       

"blatt1"..."blatt4"?
   

Maik,

Since Melchior is away for some time, but he sent me
     

the model of the
   

B�lkow to include in the base package in case you got
     

the helicopter 
   

model ready before he gets back.

I did look at the animation file and it looks like he
     

didn't add 
   

animation for separate blades yet.

In case you are creating your own modifications to the
     

animation file, 
   

you have to animate every blade by itself because they
     

don't share a 
   

single rotation axis ...

Erik
