Rocket test No.1

 This Thursday MNL went out for our first rocket test. The rules were that you can change the water level and the air pressure up to 60 psi. We were trying to test the best amount of water to add and the air pressure. The goal was to go as far and high as possible. My group was up first and we did 60 psi and 300mls. Here's how it went, 



It turned like most of the other rockets, but there were 2 or 3 that went well. Most of the rockets with less water did well  since there would have been less weight and more air. The one with 50 psi also did well since it wouldn't have gone out of control from the air coming out so fast. Here is my data table about the flights:

Notes

1.

60psi

300mls

Went up and did a u-turn.

2.

60psi 

500mls

It went high but lost control and started flipping.

3.

60psi

700mls

Started straight but the wind pushed it so it turned.

4.

60psi

200mls

Went well then ran out of water losing its fuel

5.

60psi

150mls

Went great not catching any wind.

6.

50psi

400mls

It went high then the wind pushed it.



After the first 6 flights we put on these plastic fins, to add aerodynamics and stability. The fins helped dramatically doubling the furthest distance and height easily. After a few different attempts with fins we went back to class and had finished our first test.
