Rocket Motor Performance Science Fair Projects

Rocket Science

Rocket science is a mixture between chemistry and physics. Chemistry is used to develop fuel and physics is used to develop the physical design of the rocket.

Objectives/Goals

I wanted to see what type of rocket motor will achieve the highest altitude in a high performance rocket, testing a low-thrust sustaining burn, or a high-thrust short burn motor.

Methods/Materials

I used a C6-5 and a C11-7 class rocket motors for the rocket, also used was a "scratch" built rocket with fiberglass construction. A logging altimeter to get the altitude. Also a triangulation measurement device for backup in case the altimeter failed.

Results

I found that the rocket with the C11-7 flew to 1300 feet and the C6-5 flew to 900 feet.

Conclusions/Discussion

Based on my experiment, I concluded that my hypothesis of low-thrust sustaining rocket motor was wrong. The C11-7 boosted the rocket to highest altitudes. I did have a few difficulties executing my experiment, and I plan on further research. 3rd party contributor
