Free Flight, Free Speech

With doing the ASK-13 lift/normal flight model and working from home it all became a bit of a drudge..... put one lap top down and pick up another one.... So I've taken a few months off to re-charge.

Ya might have noticed I'd been a bit quiet...

Anyway I thought what I'd do on my return is rather than jump straight back into the ASK-13, I'd do the iconic 'Huey' with a jsbsim flight model.

oh ! nice a Huey JSBsim is a very welcome addition

i'm glad you got days off, too.

And I've just discovered who thinks he owns it...

So it's a win win...

She's weight and balanced and sat on the runway... with non of that slow spinning around malarky

Just the engine, props and moments to do now.....

I thought the Scorpion gunships control system would be harder than a single rotor helicopter, what with having 4 rotors and 2 turbines.... But I was SOOOOOO wrong.

There is so much going on with so much interaction.... and procession ! who knew that JSBsim has working procession built in to it's propeller code ?

LOL
Seems the Huey is Hueying you?

What is that working procession exactly?

Well imagine a spinning rotor on a stationary helicopter...

When it comes to prop moments there's just the 1, that of torque expressed as n_moment-lbsft..

But if the helicopter rotates having a p-rads-sec... The propeller suddenly gets a m_moment-lbsft value... Equally true if the helicopter rotates having a q-rads-sec generating a l_moment-lbsft.

The result of this is that if the helicopter rolls the nose raises and falls and if the helicopter pitches the helicopter rolls to the right or left

It's like riding a bull at the moment.
