Ok, that's what I thought would happen. In my previous model I had the main lift vector over the CG and just took into account wind pushing the nose down due to the elevator. I now understand the CG is in front of the main lift vector so in a falling condition, I would have a force on the...
@berkshire Ok, I was under the impression they were balanced the opposite way for some reason and thought the elevator would provide upward force to balance. That makes sense now.
@rb1957 I'm going to modify the program to do treat the elevator and rudder as lifting surfaces and that all makes...
Sorry but I'm not clear on that last part. Are you saying that I should take the lift produced by the elevator and then add in a force created by velocity perpendicular to it?
So should I use the same model for the rudder as well?
Thanks,
Reggie
What the current simulation does is provide a fairly convincing simulation of an airplane. What it doesn't do is provide accurate results for certain scenarios. (orientation is stored in a quaternion ).
In thinking about what rb1957 said, I realized one of the problem situations is caused by...
If I take the force due to lift on the wings and calculate the torque from that and do the same for the elevator, and add a translational force for the elevator, would that correct the problem?
Also, do I need to continue adding a second force for velocity perpendicular to the elevator? If the...
Hey Rb, thanks for the reply. I suspect my modeling of the elevator and rudder may be where my problems are coming from. For the elevator, I don't do the balance you were referring to as I just assume the wing lift is above the CG and causes no rotation. I can then just treat the elevator as...
I'm in dire need of assistance in fixing an aircraft sim. I was a Math/Physics major before switching to electrical engineering so I have a good background in the area but could use a true ae to help with some of the areas that are not quite right.
If I adjust the rudder parameter for example...
