Airplane Float

Week1 Narrative
My Task

- Creating a updated airplane based on prior designs and experience from previous plane.

First Attempt

- Originally I attempted to soak the wooden skewers in wood and create an arched wing. I would was able to bend but it needed to be clamped down in a form to create the curved shape. I would need to create a form that would keep the wood in place so it could dry into the shape.

Moving On - I then decided to create a plane with a "V- Shaped" wing.

Created the Wing Using - (2) 29.5cm wood skewers bent in half

- (3) 12cm wood skewers connected the ends and middle

- (2) 4.5cm skewers extending out from bottom that will connect to the base

- Wing wrapped with plastic wrap

Created the Body Using

- (1) 30 cm wood skewer - (2) small paperclips bent around the skewer to create the support for the propeller and the mechanism that keeps the rubber-band in place

Next Steps

- Get the propeller from the other plane then create a back wing of similar weight

- Test out the plane to see how long it stays in the air

Week2 Narrative
My Task

- Learning more about dihedral wings

What is Dihedral - Dihedral refers to the angle of the wing. When the wing is tilted upward or has a positive angle to it, then it has a dihedral to it.

Dihedral Effect - When the wings are angled, it contributes to something called the dihedral effect. It is to do with the rolling momentum and factors that can contribute to it include wing sweep, a vertical center of gravity, and the height or size of anything on the aircraft that changes the side ward forces.

Effects of Increase of Dihedral Angle - When the wing angle is increased, this will cause the amount of inherent stability of the roll axis(the planes stability) to increase. However, it will also cause the amount of lift to decrease and the amount of drag to increase.

Next Steps

- Report findings to team

- Decide on which wing design to incorporate into model

Week3 Narrative
Plane is built

-Wingspan is 11.6in, Body Length is 12in, and the weight is 12.1g

Testing

-During the test run, the plane lasted for 1.3 seconds in the air.

Observations/Analysis

- After observing how the plane did multiple flips while in the air, it was evident that the plane's front and back were not balanced. The nose of the plane needs more weight on it to balance out the plane.

Next Steps

- Add more weight to the nose of the plane

- Continue testing and observing/analyzing results

Week4 Narrative
Starting a New Project

- The airplane float project was dropped, now I will be working on a new project for the rest of the semester.

- The project is the create a putt-putt course that is related to Howard Community College, is easily portable in a car, and incorporates numerous obstacles.

Ideas

Panel Obstacle Description- Have an obstacle in front measuring about 41" in length and about 1" deep. There two outside panels measuring 8" will be completely open, and the middle panel measuring 5" will open and close like a door, swinging inward up to 90 degrees.
