Hi to all

I need to visually model an airship with 4 engine nacelles for an University Project.

The difficulty: some of the engines  have to be tilted....
The configuration:
"Normal" Airship with nacelle under it.

1 engine at the end of the airship, pointing in flight direction, should be able to tilt 90 degrees downward.

1 engine at the end of the airship, pointed 90 degrees to the right from flight direction, fixed.

2 engines beside the nacelle under the airship, both able to tilt up and down.

Sounds strange, I know.
And if this is possible to model, is it possible to control all tilt-processes differently via FSUIPC?

I have experience in X-plane, ut it does not work there this way...

Would be really helpful if anyone could tell me, if all (or some of it) is possible. If not, I have to look for a solution somewhere else...

Sincerely
Jens Klaubert

well.. you could do it via primitively tagging it to the elevators\ ailerons\ rudder, or flaps (That have no effect, just move)..
what\ when exactly do they move?

and which program did you use to model it?

Dan.

Hi Dan,

so I could model 4 different props and lets say tilt two by using the flaps? That was ok.

The FLightmodel itself is running in Matlab/simulink and the data is exchanged by an UDP-interface and FSUIPC.

If you mean, what Program I use for modelling the visual airship itself, i would say gmax.
If you know something better, please let me know.

Jens

As long as you have the flight dynamics taken care of, and you're looking for the visual model, only, gmax can handle it... I presume you're already familiar with 3DSMax, etc, so gmax shouldn't be a problem.

I would suggest that your moveable engines nacelles be children of a small part - lever_stick_fore_aft (I believe) that you can animate with keyframes

Alternatively, like Dan suggests, you can name these nacelles "elevators" and make sure that in the aircraft.cfg file the elevator travel is as desired +/- 90degrees?

Visually, the animations you want are "no problem" the hardest part is getting the flight simulator to recognize and move like you want.
