Are there anyone else interested in lighter than air flight
for FlightGear/JSBSim?
Comments and suggestions are welcome!
There is a balloon fdm in FlightGear but the last time I tried it
I got some very strange results, and accelerations;)
Well, it is a hot air balloon FDM and not a gas balloon FDM.. :)
I'd _would_ like to do some Zeppelins though...
Me too, but I'm not quite there yet, or, rather, I do think the basic
functionallity needed is there (although crude), but I don't have
the skills needed to write a working Zeppelin JSBSim specification
using it yet. (My attempts tend to behave like pendulums while either
floating skywards or sinking through the ground..)
If someone wants to try, please do!
You are absolutely right about incorporating the dynamic lift
aspects of airships - it was a vital factor in their operation.
Yes, and that is why I choose to work on adding the static lift capability
to JSBSim instead of starting with some thing like the balloon FDM and add
aerodynamics - to me the static lift seemed relatively simple to
model while aerodynamics and propulsion seem (very) hard.
Cheers,
Anders
