Lateral direction motion modes (Dutch-roll, Spiral Mode, Roll) in JSBSim #1086

Do you understand the flight dynamics of the Dutch roll etc and just need to understand how to move the controls in JSBSim in order to excite them? |

Some techniques are going to be easier than others. For example for the Dutch roll https://en.wikipedia.org/wiki/Dutch_roll
So in this case you could simply use JSBSim's trim routine to trim the aircraft at some specified altitude and speed and then simply input a singlet or doublet of either the rudder or ailerons and then graph the output. And if you wanted to/needed to you could edit the relevant stability derivatives in the aircraft's FDM in order to demonstrate how the Dutch roll dynamics change. For some of the other techniques, e.g. you'll need additional logic over and above simply inputting a singlet, doublet etc. Take a look at the following discussion for an example where I used Python to implement a rudder-kick maneuver that someone was asking about - #519 |

Hello,
I'm interested in exciting and visualizing lateral directional motion modes such as Dutch-roll, Spiral Mode, and Roll using JSBSim.
Could anyone please guide me on how to excite and visualize these lateral modes? Any pointers or resources would be greatly appreciated.
Thanks!
