Subject: [Jsbsim-users] Problem in trimming the aircraft

 

Hi friends, I am a flight dynamics student, I am new to jsbsim as well. I am trying to simulate a trim maneuver. I have run jsbsim with both the stand trim script file for the 737 aircraft and also tried the tutorial by  Bill Galbraith, I see that there is a step change in output . Please kindly see the plots. I don't  see any  gradual trimming. like the plots given in  Bill Galbraith's tutorial document, 

 

Attached files  are 

Altitude vs time plot for Bill Galbraith tutorial case : 

Theta Vs time plot for 737 with the 737_cruise.xml script file .

 

Please kindly help , I would like to reproduce the results in Bill Galbraith's tutorial and then do similar runs of the 737 aircraft

Please also kindly guide me and correct me if I am doing something wrong. 

I have made no changes to any of the default xml script or aircraft xml files 

 

Sincere Thanks, 

Regards 

Shree .
