 Week 4: Taking Flight

What is Aerospace Engineering?
Aerospace engineering is the type of engineering that involves the design/construction of aircraft and spacecraft, along with other things like making cars aerodynamic. 
 
Our Finished Plane
Our Plane Takeoff
We had calculate the center of pressure, shown above.
We also had to calculate the center of gravity, which in order to do so we balanced the completed plane on our finger.
In order to make sure the plane was stable, we made sure the center of gravity was before the center of pressure.

Our plane didn't fly well and we believe it was either due to the operator of the controller or the motor didn't provide enough thrust.

Our Landed Model Rocket
The Launching of the Model Rocket
The calculations for the center of pressure for the model rocket are shown above.
The center of gravity was determined by balancing the rocket on our finger. 
We wanted to get the center of pressure behind the center of gravity, so the rocket would be stable, but we were not able to do this, even when we added weight to the front of the rocket and decreased the area of the nose. 
Bottle Rocket/ Glider
Our rocket/glider didn't go anywhere because, when the tether was pulled, it just exploded shooting water and the fins off. If we had more time we would go back and see calculations to see what went wrong.
