Flight modelling trivia

[Krusty]

If a plane is in a steady 45 deg banked level turn to the left.  Which wing is producing more lift.

HiTech

I seem to recall a comment that the wing produces the same lift no matter what the speed. So wouldn't the answer be "both produce the same"? Otherwise you'd be rolling into the turn or away from the turn. Also, this assumes the inner wing is not stalled, which disrupts/kills the lift on that wing.

[Trukk]

Does the aircraft have any dihedral?  If it does the inner/lower wing might actually be producing more vertical lift.

My answer to Fester's original question:

 



-----------

As for hitech's question, very evil indeed.  Almost as evil as what creates lift.  

The answer of course is "it depends" .  There's a whole host of other factors besides differences in relative velocity between inside and outside wings... sideslip, yaw, dihedral, cross-flow, power effects, vortex side-wash just to name a few.

For Krusty & kvuo, rolling moment = 0 doesn't mean that the wings lift are equal because there are various other variables that contribute to rolling moments.

Your a party pooper, btw the form of the equation you posted also can answer my question because the sum of all torque about the roll axis must be zero in the turn I described.

Also for most of the planes in our game, My gut tells me the prop is the primary torque creator hence it would be the wing that counters the engine torque.

Dtango, why this is not possible in AH2 ?

[Zeagle]

it is already, see SpitXVI, P-51, F4u and P-38      

But seriously, that kind of maneuverability has to do with a !@#$ load of thrust from the prop combined with a lot of prop wash over the tail, and low overall mass. The plane becomes kinda like a helicopter...I mean they can and do stand on their tails. Amazing to see. RC or full scale.

A ton of power to weight ratio is what makes that bird do silly tricks.

Your a party pooper,

lol, i should have left my statement at your question was       and stopped there.  But my mother's teaching of not watching people run around with physics scissors got the best of me!

you'll have to ask hitech & pyro about that.

ahh indeed. see, I either thought it was a trick question, or a very complex question.. It turns out to be complex

I did not even think of propeller torque.

If a plane is in a steady 45 deg banked level turn to the left.  Which wing is producing more lift.

HiTech

If engine is a clockwise spinner (engine torque force counter-clockwise) then the bottom wing will be producing a little more lift based purely on balancing the moments.

That's what I thunk anyways.  I'm probably rong.

Ya...let's find that plane in the hanger....


What plane number is it again?

no fair comparison, Lepape is godlike in a P47      that goes for Jug to
