1 Introduction
When designing an aircraft, it’s all about finding the optimal proportion of the weight of the vehicle and payload. It needs to be strong and stiff enough to withstand the exceptional circumstances in which it has to operate. Durability is an important factor. Also, if a part fails, it doesn’t necessarily result in failure of the whole aircraft.
The main sections of an aircra
First, Substrate is consists of a plastic or glass, a portion of the OLED is supportive.Anode is a role that make electron holes when current flows by removing electron. And the upper Conducting Layer is the place that Electron Holes is being created.Emissive Layer is the place accepting an electron from Cathode and produce light.
Emissive layer and conducting layer are called organic layer beca

4.1. Wing structure
Wing structure
The wing on the plane is a part that the highest load take. The large bending moments especially act on the point near the root of wing. Also, we should consider the number of spar, rib, position, skin thickness and taper ratio.

Beam theory shows that the I-shaped section is a very efficient form f
