Intro:

This assignment was to build an airplane out of balsa wood and fly it. We were given a bag with all the parts to make the plane. We are doing this because it is part of our flight unit.

Building:

First I cut my pieces out of the 2 planks we were given and put together the plane. Then I glued the parts and engine in place. Lastly, I sanded it down to make it more aerodynamic and attached the wire to power the engine.

Materials

• balsa wood
• engine
• wire
• propeller
• glue
• elastic bands

Conclusion

What worked well for me was putting the plane together. It went relatively fast and was easy. something I would do differently is making a different type of plane for the challenge of making my own parts because I think that could be fun.

Intro

This assignment was to build a model rocket and create fins and a nose cone on onshape. I am making this because my teacher told me to. I hoped to learn more about how rockets fly.

Nose Cone / Fins

I chose these designs because they looked the best in my mind. I did some research on the nose cone to see which would be the most aerodynamic and my design is pretty close to the one I saw online.

Flight

Conclusion

making my rocket was pretty easy. something that went wrong was that one of my fins broke after my first flight so I would do a better job gluing them next time. Something I would do differently is not use hot glue, hot glue is heavy and gives more drag.
