This was my first rocket. 3 fins and a pointy nose. Taping the top of the tube and connecting the nose cone was kind of a pain and could be improved. Went pretty far though!

This instructables post was the inspiration for the project. The post is mostly about how to build the launcher, but contains some rocket building instructions towards the end (Step 13)

# data[].attributes.attachment_link.description
Air Powered Rocket Launchers V5.0: This project started as a simple request to make a previously designed paper rocket launcher for STEM events. The original design had many flaws, and hopefully I’ve mitigated most of them to make the launchers safe, easy to use, cost effective, and …

1) What is the design idea you are testing?

2) Insert a picture of your rocket(s)

3) Test your rocket (preferably multiple times) and record the data like so:

Design #X

Test 1:

Air pressure: XX psi

Distance traveled: XXX ft/m

Test 2:

Air pressure: XX psi

Distance traveled: XXX ft/m

Insert a picture of your first rocket?

How well did it work?

Any thoughts on how to make it better?

# data[].attributes.body
As a group, brainstorm ideas for making rockets that travel further. Record these ideas either in a google doc or visually on paper and insert/link in a post

Include:

What design idea are you testing?

Change the angle of launcher

Adding weight (paper clips or dimes)

# data[].attributes.body
Not bulky

Stylish but simple

Rocket nose is taped well (no air gaps)

Weight distribution

Three or four fins

Nose cone is pointed

As narrow as possible

Test Rocket 1:

Narrow nose

Three fins

40 PSI

Horizontal length: 137 feet

Test Rocket 2:

Narrow nose

Four fins

40 PSI

Horizontal length: 154 feet

Didn't travel that well needs to be tighter with tighter cones and fins on all sides.

Flew over to the YMCA parking lot. Never to be seen again

# data[].attributes.body
Flew really far, hit the ground hard

# data[].attributes.attachment_caption
Shorter than others, Flew really fast into a tree

# data[].attributes.body
This definetly not flying

Final rocket 1:

Narrow nose

Regular barrel

Four fins

30 PSI

Horizontal length:

Final rocket 2:

Narrow nose

Short barrel

Three fins

30 PSI

Horizontal length:

Final rocket 3:

Narrow nose

Regular barrel

Five fins; 2 high on the barrel and 3 low
