Tailplane Lift and Pitch Moments
Posted: 19 Jun 2006, 03:26
At the outset I should point out that I am not a FlightSim aircraft designer, I know nothing about the inner workings of FlightSim, my FD expertise is extremely basic (ie: of the sometimes hazardous "Trial & Error" variety) and my piloting skills are none too crash-hot either.
That said, I'll dive in at the Deep End and ask ....
Can anyone explain to me why FlightSim aircraft designers and/or their FD "experts" completely ignore the Lever Arm Principle when determining Lift/Side Force and Pitch/Yaw Moment parameters for Elevator, Horizontal Stabilizer and Rudder in Record 1101 of the .air file ?
I'm no aerodynamics expert either, but it is my understanding that [Lift/Side Force] multiplied by [the longitudinal distance from the FS Reference Position to the Point of Lift/Side Force] equals [Pitch/Yaw Moment].

David.
