Perhaps one day in the future. My plans right now are to do a Fokker Eindekker after this, but I'll definately keep it on the list.
Fokker what? ;\)

Great start to the Eindekker.

Can it be animated for wing warping? If so, I imagine it will be difficult to do.

That DH-2 is looking amazing Aladar! Can't wait to fly it!

I have been hoping that someone was going to do the Fokker Eindekker. Looking very good RussoUK2002!

Aldar:
Thank you for including all that torque in your DH-2 FM. Most people do not realize just how much torque is in a rotary engine and to be historic/real, it needs to remain in the FM.

I just hope all the other FE FM modelers keep the torque in for their rotaries too. After all, this is one of the main reasons that WW1 planes were so manuverable (using the torque to help in flying).

I read one account a couple of years ago of a modern pilot flying a "reconstructed" Nieuport 11 and he said that it's small rotary engine made so much torque that in flying straight required him to put the stick clear over to the right side to counteract all the torque. As a result, rolling/turning left was very easy, but rolling/turning right was very difficult. So keep all your torque please because the DH-2 was not an easy plane to fly either from what I have read.

Actually, wing warping would be very easy to do. FSWWI taught us many cheats.



Anywho, Russo, I didn't say Fokker Eindecker, I meant Morane Bullet. :p

Tiresome point of physics, there's no more torque in a rotary engine than any other of the same HP and RPM. No, really, there isn't.

These a/c have high torque because they have low rpm. And big fat props. Also a reason why a modern replica with a higher-revving radial and a smaller prop doesn't quite fly the same.

Actually, in FE it doesn't even require any cheats or trickery... The warping can simply accomplished by twisting/warping of the verts in an animation key frame.

Hmmmm.... thats too easy.

This animation would be similar to the way the afterburner aperture movement is accomplished in other TW titles (which is scaling..BTW)

5054,

Sorry, won't wash. In piston engine aircraft the overall torque effect is a combination of rotating mass and prop pitch. Changes in propeller pitch will cause short-term torque-like reactions. The torque from the rotating mass never goes away, though it varies by engine speed and its effects are mitigated by the stabilizing influence of the aircraft's slipstream. Thus, a P-51 had to be handled carefully on takeoff, when engine speed and prop pitch were both increasing, yet had fairly stable flight characteristics at cruise.

Early rotary engines rotated the entire cylinder and block assembly, which masses much more than the crankshaft, rod, and pistons of a radial engine, for instance.

I think you may be confusing modern rotaries like the Mazda with the older types. The rotor on the Mazda spins within an outer housing -- block assembly, if you will. That's not how WW1 rotaries worked.

The heavy torque had advantages and disadvantages.

One reason "full motion" rotaries quickly became obsolete was the substantial stress they imposed on the mounts and airframes, not to mention the pilots. As I recall (my library is in storage pending a move) that there were more Camel pilots killed in crashes than by enemy action.

Mmmm, a Fokker to be fodder for the DH2's gun. I can't wait. An EIII is essential.

TK says wing warping is possible via animation...heres what he said...(topic was for animating control surface wires with ailerons and elevators originally)
...
Capun asked..."It looks like you can animate the control surfaces like rudders, ailerons, etc. So for the WWI stringbags we could animate all of those wires moving the control surfaces.

So to animate a control surface, lets use the Elevators as an example

AnimationID=X

Frame 1= Elevators Up

Frame 5= Neutral

Frame 10=Elevators Down

I think you can also use the ReverseModelOrientation=TRUE with this animation"...

heres TK`s reply...
"You have to animate everything so

1=Up
10=Down

And if you watch carefully, keyframe 5 isn't at the center. (because frame 1-10 gets mapped to time 0-1.0, exact halfway point ends up being at keyframe 5.5).

If you're careful, you can also do wing-warp animation with this.

TK "
