The wing structure study marked a critically important moment in Leonardo's endeavour to design a machine capable of making mankind fly. This drawing shows a bat-wise wing with a wood and cane frame covered with fabric stretched all over. The wing, with its veins and covering, is made up of a deal shaft with cane spokes leading off from it.
The model is based on the drawing:
