Let me show Nose landing Gear 3D model for ATR72 aircraft in order to study easily. This animation is not exactly the same with real one. But, I tried my best. Landing gear system is difficult to see clearly. i.e, unlocking mechanism, Door operation, Bellcrank, Springs, and actuators. etc. After you see this, I hope that you all will like this. I know that some other components are also required and some are not the same. Next time, I hope that I can update.
Thanks for everyone
