=Week 0 Introduction=

=Week 1 Narrative= Task: Draw models and refine design solutions based on prior tests.

Past designs:

Video of test: http://www.youtube.com/watch?v=IP1HDcLxiFE&feature=youtu.be

Things that went wrong:
 * Propeller did not generate enough power to push the plane forward
 * Plane tend to swing backwards

Things to consider:
 * Tail too heavy causing the plane to swing back
 * Adding drag to slow down the propeller
 * Adding friction to slow down the unwinding of the rubber band

=Week 2 Narrative= Task

-which wing will create most lift

Types on wings

Different types of wings


 * Last models tend to roll and were unstable. Dihedral is the design that controls roll and stabilizes the plane.

How dihedral will help

-Since the plane will not roll as much and be more stable, it will allow the propeller to move the plane forward while the wings lift the plane upwards.

Degree for maximum lift

Next Steps

-Put into model

-See whats the best option for the final plane

=Week 3 Narrative= Beginning of the week:

Wingspan: 12in

Body Length: 10in

Weight: 7g

Next steps:
 * find a open environment with no wind and test the model.
 * record data
 * refine the testing protocol and include a force used to throw the plane variable.

=Week 4 Narrative= Plan

-Incorporate the keys factors that worked in previous test into this model.

Model

-V shape wing(15.75in X 7in)

-15.5in body (straw with tail at the end)

-flat rectangle tail wing (10.75in X 5in)

-Propeller 17in (last made model)

Moving forward

-The Airplane Float project was recently shut down because it was not being moved forward.

Putt-Putt Golf

Objective

-Built a golf course that:


 * Has a Howard Community College theme
 * Has at least 10 different obstacles
 * Must be transportable (fit in a car)

Ideas

-Duncan the dragon's mouth that opens and closes (powered by an arduino)

-Includes 3 different path options

Design Ideas

Next Steps

-Learn how to use the arduino

-connect arduino with a motor to use for the head on the dragon

-Figure out sizes and dimensions for obstacles in the design
