What follows is a brief introduction into some methodologies and analyses typically carried out during the design of a new wing structure. %PDF-1.7 Examining the mathematics behind a shear flow analysis is outside of the scope of this introductory tutorial; rather the methodology and rationale will be discussed. Limit loads are therefore multiplied by a factor of safety to arrive at a set of Ultimate Loads which provide for a safety margin in the design and manufacturing of the aircraft. An example of the distributed lift load and resulting shear and bending moment diagrams arising from this loading is shown below. Welcome to part 6 of a series on an Introduction to Aircraft Design. Before the structural layout of the wing is designed, a preliminary sizing of the wing planform should have been completed to size the wing for its required mission.

I’m only “assuming” there are similarities to how the B737max wings are also held in place. of an aircraft wing. However, starting with some hand calculations, similar to those shown above is a good way to begin the design process as it ensures that the engineer understands the resulting load paths before creating an FE model. � QE �p��U�)�M��u�ͩ���T� EPEPEP0��(��er0X�(��Z�EP0��( ��( ��( ��cȫ�'ژ7a�֑W��*-�H�P���3s)�=Z�'S�\��p���SEc#�!�?Z�1�0��>��2ror(���>��KE�QP�s?y�}Z ���x�;s�ިIy4�lch>�i�X��t�o�h ��G;b]�����YN� P}z�蠎!�/>��J �#�|��S֤�� (�� (�� (�� (�� J(4PEPW}MU�G�QU�9noO`��*K In part 5 we looked at the role that the airfoil profile plays in determining the flying characteristics associated with its selection.
