### what did we do?
decide the airfoil

| 項目 |GOE56 | NACA0024 | NACA4421 | RAF89 |
| --------| -------- | -------- | -------- | -------- |
| 升阻比 | 2 | 4 | 8 |5 |
| 攻角與升力關係 | 3 | 3 | 9 | 6 |
| 厚度是否可放置伺服馬達 | 5 | 5 | 5 | 5 |
| 製作難易度 | 2 | 6 | 6 | 2 |
| total | 12 | 18 | 28 | 18 |
scale: 1~10/per

* NACA44221 is the best choice**
### what will we do?
- [ ]Make it!

## 3/24
### What did We do?
design the frame of our AUV

### What will We do?
- [ ] make the hardware CAD carefully

## 3/31
### What did We do?
1. Built Tim's plane and Try to Make it fly
2. Take video for the Planes

### resault
1. **"both"** crash
2. Make our video successfully

### What will We do?
- [x] repair the plane

## 4/3
### What did We do?
1. Decorate our plane
### What will We do?
- [ ] Put our sponsors' Logo on our plane

## 4/12
### What did We do?
1. Design the frame of our wing
2. Design how to operate the control surface.
3. Decide the Material

| 項目 | 材質 |密度 or 重量|
| -------- | -------- | -------- |
| Airfoil | Balsa | 0.112g/cm^3 |
| rob | wood | 0.56 ∼ 0.86 g/cm3 |
| SG90 | plastic | 9g |
| square rob | Carbon fiber | 1.98g/cm3 |
### What will We do?
- [ ] Manufacture

## 5/18
### What did we do?
second real flight
#### detail:
fault reason:
the mass center is too back
the wind is too big

## 5/27
### What did we do?
Make the wing frame

## 6/3
### What did we do?
find out the thruster we need

## 6/4
### What did We do?
1. finish the tail

2. find out the mass cinter and moment
質量 = 1359.00 公克
取於質量中心，並且對正輸出的座標系統。
Lxx = 90748398.97 Lxy = 5791603.57 Lxz = -417011.59
Lyx = 5791603.57 Lyy = 162856578.59 Lyz = -111707.05
Lzx = -417011.59 Lzy = -111707.05 Lzz = 77137023.55
## 9/23
### What did We do?
1. 組裝第二代機翼

## 9/30
### What did We do?
1. put the Servo on the wing
2. make a control surface

## 10/01
### What did We do?
1. Make the Wing Covering

# high light Note
## how to find out the airfoil?
1. decide the flying altitude and the flying speed than you can get the Renold number.
2. measure the weight of the plane than we can find out the lift-drag ratio
3. choose the best airfoil in airfoil tools
4. analysis it by xlfr5
5. Safery is the most important thing

## What I'm planning to do by solidworks
1. find out everything we need to put on the plane
