Nice to meet you GT.
Seven-G is such a good job. So very Appreciate of it.
But I\'ve found some small problems with the flight simulation like
Why was that the flight parameters of F-18 in 7G always change rough but not continuously during high frequency and high scope control of AOA, and easily lead to a stall even in an AOA lower than 25 Degree?
For example, when I roll 180 degree to change heading of turning when in a scissor.
commonly,pushing the stick to decrease the AOA might help to increase the rolling speed, But in Seven-G, when I push the AOA from 25 degree to 0 or -5 degree quickly, and very next, I pull the joystick again to build anothor high AOA of turning, The AOA limmit of contol system seems not woking and the AOA increases fast exceeding 34 degree(critical AOA) easily and lead to a rough stall...... Meanwhile, the movement parameters of F-18 start to change suddenly.
This situation puzzled me a lot. I can\'t imagine that AOA limmiter of a fly-by-ware fighter such as F-18C has the bug such like this. Even training Jet of China Hongdu(L-15) serves this problem well. So I suggest you sincerely to check for the control model (especially the AOA limmiter) again, maybe there\'s still some bugs[s:6]
By the way,was your flight model be based on NASA-TM-107601(Simulation Model of a Twin-Tail, High Performance Airplane)?Where can I find its whole modeling data?
Thank you for your exellent work again. And I wish I could see an exellent flight simulation of F-18 in the near future[s:6] |
