4. STRUCTURE DESIGN
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.
I Beam shape
4.2. I Beam
Beam theory shows that the I-shaped section is a very efficient form f
3D printing
3D printing or additive manufacturing (AM) refers to any of the various processes for printing a three-dimensional object. Primarily additive processes are used, in which successive layers of material are laid down under computer control. These objects can be of almost any shape or geometry, and are produced from a 3D model or other electronic data source.

1. 3D 프린터란?
3D프린터는 3차원 물체의 형태를 출력할 수 있는 장치이다. 지금까지의 출력방식인 평면 그림이나 글씨를 종이에 출력하는 것(2차원)과 달리 구와 같이 3차원적 사물을 만들어내는 것이고 그 출력 방식 또한 여러 가지가 존재 한다.
3D프린터의 가장 큰 장점은 복잡한 형태의 형상이라고
Keff, Km, Kp : the effective thermal conductivities of the composite,
Metal matrix, Particles
φp : the volume fraction of reinforcements
a : the diameter of the reinforcement
- hc : the boundary conductivity.
Advantage
The air travels across the short
length of the fins laterally, rather than longitudinally down
the long length.
