Transcript of Wind Turbine
By: Shirley I., Angel C., Brandon L., Elizabeth C., and Jonathan P.
DC brush less motor
Efficient and economic artifact to produce energy enough to charge batteries without the need of external energy.
The Body Structure
Wood to give support to the rest of the design.
Hollow rectangular box that measures 3ft*3ft*6in
4 basic parts:
They all work together to produce the energy desired and generate power to charge the battery.
Criteria and Constraints
Blades determine how much energy is taken in and turned into volts.
10 degree angle to make them as aerodynamic as possible
Made of PVC pipe
Length of 1 ft.
3 ft tall, horizontal PVC pipe that will support the whole artifact and connect the motor to the base
We don't need taller structure, but we could place wind turbine on top of a taller surface; only need enough energy to charge batteries
If there isn't wind, we'll create wind
Higher altitudes=More wind
Average size-More manageable
The components are the parts of the artifact that hold on to the main parts and make it work.
DC brush less motor because it would give us the least friction and more work.
Disk that will be attached to the blades on one side and on the other side it will be attached to the motor to recluse the energy.
Bike chain that we will attach to the blades' disk to the motor which will make it spin at a more controlled speed.
no bigger than 4 feet
no more than 20lb
Blades- the more blades, the less rotor efficiency
Tip of Blades- Tapered tips means there is less noise
Rotor Diameter-Bigger is better; larger area can be swept
Aerodynamic Rotor Drag- the drag acting on the rotor and blades is the most significant
THANK YOU FOR YOUR TIME AND STAY GREEN MY FRIENDS!
Calendar/ Next Steps
Design model on Autodesk Inventor
Easy to transport
Have a moderate to low RPM
Produce 12 volts
Computer controls motor
No sparking and much less electrical noise
Uses electricity and a magnetic field to produce torque, making it turn
Simple design and reliability=good choice for many uses
AC motors will turn at a constant rate, while with DC motors you can turn supply voltage up or down
The Schematic of the Turbine
Blades and Disc to Attach Blades
Different Types of Blades
