Business Case: (“WHY” should this project be done? Identify the specific current and future business needs that this project meets. State how the proposed project aligns with the strategic objectives of the business area and organization.)

Innovative methods to save energy are needed with continued escalation in energy costs. One area is in

automotive applications where the objective is to increase the efficiency in miles per gallon(mpg). Moving an average vehicle through still air at a velocity of 70 miles per hour(mph) requires from 30 to 80

horsepower depending on the design and size of the vehicle. This energy is wasted and not recoverable. One method to recover some of this energy is to utilize a fan or turbine to convert the moving air to

electrical energy. Depending on the size of the fan and generator that is powered by the moving air, up

to 1 to 2 horsepower could be generated at 70 mph. If the air driven generator could supply the vehicle’s electrical load at highway speeds, this would reduce the load to the gasoline driven engine thus

increasing gas mileage. Average gas mileage could increase up to 5 mpg if a wind driven generator could supply the electrical energy to the vehicle at highway speeds. This project is to evaluate the feasibility of

this concept. If proven by laboratory measurements, air driven generation of automotive electrical energy

would have a significant impact on fuel usage. In addition, an engineering project of this type would result in patentable inventions and potential monetary benefit to MTSU. A successful program would lead

to visibility for the University and increased student enrollment. These objectives are in line with the strategic goals of the University.

Scope /Project Deliverables: (“WHAT” will the project deliver? Scope answers the question “What will be done on this project, and what are the products or services that will be provided? Deliverable – What are the measurable products, components, and services produced by the project? How will you know when you are “DONE”)

A laboratory-size wind tunnel will be designed and built to provide an adjustable wind velocity from 20 to 70 mph through a circular tube having an 18 inch inner diameter and 8 feet long. A fan driven D.C.

generator will be positioned at one end of the circular tube connected to a suitable resistive load with the capability to measure generator output current and voltage. Measurements will be taken to determine the

maximum electrical energy generated by the fan driven generator as a function of wind velocity and fan

blade pitch. Maximum electrical energy will be measured for at least three wind velocities and at least 3 different fan blade pitches making a 3 X 3 matrix of data. The project is complete when all nine

measurements have been taken and documented.

Success Criteria: (“HOW” will the output of the project be measured from an operational perspective? What tangible business value

will result from doing this project? What must occur in the business area after delivery for us to say the project was a success??)

Energy data from the measurements will determine if wind driven fan electrical generation is feasible for

automotive and/ or truck applications. If it is determined that sufficient electrical energy can be generated by utilizing wind energy at highway speeds, then the next phase of the program would be

initiated: a field test on a vehicle. A positive result in laboratory measurements will also result in a patent application which could result in monetary benefit to the University. The project is therefore a success if

the data justifies a field test on a vehicle and a patent application for the concept is prepared.

Life Cycle Cost Ramifications: (What are the long term savings and costs of the project to the business area and organization?)

The long term savings resulting from this project are reduced dependence on fossil fuel for transportation. After initial feasibility demonstration costs and costs associated with obtaining a patent,

long term costs to the University are minimal. The University will benefit from royalties paid by

automotive manufacturers to use the idea and also by increased student enrollment from the visibility of a successful development program.

Impacted Organizational Groups: (What business areas will be impacted by the project?)

MTSU/ETIS from patent royalties, increased student enrollment, and visibility to the automotive community.

Options Considered (Technical, Business Process, etc.) (What other options or solutions were considered to solve the business problem or opportunity?)

Feasibility was considered using a motor vehicle. This approach was determined to be too costly and

complex compared to a laboratory demonstration of the concept.

Project Assumptions: (What assumptions or factors could interfere with the project work or compromise the contribution the project can make to the business area or organization?)

Other projects utilizing the resources needed for this project, such as the prototype shop facilities, could impact the schedule for this project. Technical concerns such as generator design, fan design and load

resistor could delay the project.

Constraints: (What factors could negatively affect the performance of the project? Include factors that affect when an activity can be scheduled, or when a resource can be assigned, etc. )

Improper generator fan design, improper wind generation design, resources not available such as shop

time or mechanical design personnel.

Key Project Issues: (What are the barriers to project success?)

Limited resources in design and fabrication of all the components of the system. The possibility that there

is insufficient power generated by highway wind velocities to make the project feasible.

Risk Events: (What events or conditions that, if it occurs, will impact the project objectives, deliverables, schedule, budget, etc. ?)

Mechanical designer and fabricator sick or on unplanned vacation. Physical limitation to how much power can be generated from wind velocity at highway speeds.

Next Steps or Actions to Be Taken: (What are the major steps or actions to be taken to proceed with this project?)

Obtain suitable cylinder for wind tunnel and start design and assembly of frame.
