New Nose Cone

When our rocket landed after our first test launch, the nose cone was dented. We took advantage of this situation and remade the cone using a parabolic shape.

Testing - Day 4

Although our angles to find the height the height were horrific, we were pleased with our results. We are not exactly sure how high our rocket went, but we will keep testing to find out more. Rocket Balboa received multiple impacts, that slightly damaged the nose cone. We added more clay and tape to the cone, to add a parabolic shape.

Rocket Construction Day 3

We successfully attached the nose cone to our rocket, and reinforced the attachment of the fins. Unfortunately, we were unable to get a picture of our rocket.

The Fins!

We made fins using parallelogram-shaped pieces of cardboard. We added pink duct tape for support and style.

The Beginning

This is a picture of our original bottle. It holds 1 liter of water, but will only be filled a quarter of the way up.

Design and Construction

We decided on a traditional cone shape for our nose cone, because a parabolic shape would be too difficult to create. We decided to make parallelogram shaped fins. Both the nose cone and the fins have been created, and the fins have been attached.

Blueprint

Research Summary Day 1

Because our rocket will most likely be traveling at subsonic speeds, the best cone shape would most likely be a parabolic or rounded cone. The fins should be rectangle or parallelogram shaped.
