I suspect that twist to vary with load.
The twist should not vary with load, but the coning angle

Indeed so. ;) (already sorted out)
The chinook used to have just an Stability Augmentation System the SAS for
short. You still did not want to take your hands off the cyclic but it made
it somewhat smoother.
Yea I read a little about

But you don't *want* the rotor to be straight. Assuming a constant
airfoil section along the length of the blade, you would want a constant

Actually, I thought that was just a brain fart and you wrote higher and
meant lower :) It was a little confusing.

Using Tomcat but need to do more?

There is (was?) also an odd bug occuring from time to time, where some

AFAIK, the yasim fdm-engine does not simulate rotor blades with twist.
Chinook blades are twisted as much as 12°. (for stability reasons)

I suspect that twist to vary with load. It's the tips that has a 12° higher
incidence (sic!) than the root, when the rotor is stopped that is. I guess
that's

Is there any other helicopter (3D-model) in preparation?
Hello Maik,
I was fiddling with mainly the FDM for the Chinook last winter, and have a
simple 3D for it. (only an untextured exterior fuselage with two non-rotating
rotors
and the four wheels)
Hi Joacim,
I am surprised how many helicopter types are (more or less) in process.
The ch47 simulation is only a proof of concept. It shows, that the rotor
simulation is able to simulate this rotor configuration (It has 4-blade
rotors, it is much to small, no parameter of the rotor is form the
Hi Josh,
yes, it has impact on the autorotation. But I hope that it is possible,
to simulate autorotation as a first attempt without it. Most model
helicopter have no twist and are able to fly autorotations.
