Seriously skilled heli pilot

You beat me to it. I had the intention to post it here, so I settle for the YouTube version.

And yes, I am duly impressed.

I have never seen that impressive helicopter flying since I saw that video of a clown and a helicopter in a in a stock car arena. To bad I can not seem to find that video again.

[Buckaroo]

I watched this again and again and again. It's almost unbelievable.

Here's a different view of the operation from the helicopter perspective:

If anything, that for sure did not make it less impressive. Wow!

Thanks Buck for that view!

[someguy]

Thanks for that one, Buck.

[Groucho]

And yes, I am duly impressed.

Not to mention the stress he puts on air frame, mechanics and engines. That stresses the MTBF a lot.
BTW on the second view from the cockpit one can see that there are at least 2 helicopters operating.

[Hooray]

That looks like a lot of fun, I think if we could replicate this in FlightGear, it would be an awesome addon to FlightGear, sort of a challenging gaming element based on real life
I think we should have most ingredients for this ready in FlightGear, i.e. the bo105, support for external loads and -of course- Nasal scripting.

I am volunteering to help with the scripting side of things, now we only need guys familiar with FDMs, helicopters and 3D modeling/animations.
Any takers ?

I think JSBSim has better support than YASim for modeling external loads and external forces, right ?
And this could help convince some of us that flight simulators (and especially helicopters) should not be flown with just a keyboard

[StuartC]

Yasim has the better payload support + Yasim Choppers are also better as the fuselage is taken into account. I believe JSB chopper FDM's dont do that.
Not sure how you would go about including a payload thats basically flexing and changing position with the relevant forces in ether FDM though.

Not sure how you would go about including a payload thats basically flexing and changing position with the relevant forces in ether FDM though.

The payload gets its position updated by an equation of motion computed in Nasal.

It feels its intertia and the gravitational pull, based on last and present position we have a velocity vector on which to operate drag, and the distance between load and helicopter is pushed into a rope force equation - when the rope is tight, it exerts a lot of force propertional to the tension, when it's not then there's no rope force. Oh, and we need to check if it touches the ground of course...

Assuming the payload is approximately symmetric that should do the trick - we have frame spacing, so we have a Delta t, we have present and last position, i.e. a Delta x, which combine into a Delta v - that's all we need to solve a discretized equation of motion.

It's not actually that complicated

[Johan G]

I believe JSB chopper FDM's dont do that.

It's all up to the numbers one uses for the tables.

[Hooray]

we should add a new branch for this and see what we can come up with

please keep it coming folks!

[Johan G]

Finally possible in FlightGear thanks to wlbragg.

[...] here is video demonstrating the main concept that inspired the creation of cargo hauling capability.

[Hooray]

Just in time for christmas
That's one of those things that could be integrated with Marius_A's missions system, so that people get a score for their flying performance

[www2]

@Hooray you can better say: Just in time for FSweekend

[Hooray]

not sure how well it is currently suited to be really used as a "game" (or even just a challenge) - some kind of evaluation may make sense, and maybe some Flite TTS integration live commenting on your performance

Also some kind of GUI dialog to start/reset the whole thing and change a few parameters.
I guess wlbragg would be in a better position to judge if this is even suitable to be shown at FSWeekend ?
