Day 3

Rocket Assembly

We assembled the rocket using the parts of the rocket, such as the rocket body, nose cone, and parachute we made on Day 2. We attached the motor mount at the bottom of the rocket. This will accommodate the motor engine that will launch the rocket when ignited. Then, we places wadding paper on top of the motor mount. This functions to make sure the charge from the motor shoots straight up. Next, we attached one end of tension string of the parachute to the nose cone and the other end to the body of the rocket. Next, we stuffed the parachute inside the body and closed the top of the rocket body with the nose cone. This parachute is supposed to eject when the rocket is falling.

Swing Test

We tied a string around the center of gravity of the rocket and performed a swing test. Our rocket passed the test because it was able to swing around in a circle, nose first.

Rocket Test Launch

Our test launch was partially a success because the rocket was able to go in a relatively straight line up. However, it did not go very high, and the parachute ejected when our rocket was already on the ground. From our launch, we inferred that our rocket did not reach a high altitude because was too heavy.

Rocket Adjustments

To make our rocket lighter, we decided to reduce the weight in the nose cone, which would require taking off a nut we attached on a bolt that is glued to the nose. We also reconstructed our parachute so it would fit in the rocket body firmly, but is loose enough that it can be easily ejected in the air.

Capacitor Plane Fix

Since the motor broke when testing the plane on Day 2, we fixed the plane by replacing the faulty motor with a new one and resolder the wires that were attached to the previous motor.
