Front frame of the helicopter Winner B250

Same context as the previous project. This project focused on the front part of the frame, supporting the control system and the passengers. This frame must resist to extreme cases given by the Airworthiness Requirements. The main difficulty was stating the right assumptions without compromising the resistance and the lightness of the frame. I also had to think about the way the frame will be built to reduce the cost and the building time. The pictures hereunder show the results given by Abaqus and Ansys for several load cases.
