This week the Humvee was moved to Melheiser's garage in Petersburg, IN. The HEV Wraith team is very excited to begin working and "getting their hands dirty." We are now trying to meet twice a week every week either at the garage or at the school. We are starting to get everything planned and hopefull by the end of the month will have things taken off of the Humvee and have our tools and new components at hand. The students plan on uploading a video blog sometime soon.

Recently the Southern Indiana Director for Senator Lugar's office came and visited Pike Central High School, later an article was posted in The Lugar Letter and here is a copy of what was written.
Larry Ordner, Senator Lugar's Southern Indiana Director, visited with students at Pike Central High School, near Petersburg, who have partnered with Navla Surface Warfare Center Crane to convert a diesel-powered military Humvee into a hybrid electirc vehicle.
The partnership between one of the U.S. Navy's premier research facilities adn a rural southern Indiana high school has challenged twenty-five students, ranging from seniors to frechmen, to put their math, writing, science, public speaking, adn chemistry skills to work on a high-level, real-life engineering project.
"You actually see your ideas come off the paper," said Alex morton, a senior," It has reassured me that I wnat to be an engineer." Among a long list of goals, the students are determined to increase fuel mileage and torque adn decrease vehicle noise, which should result in significant operating savings.
Students are putting long hours on the project, including after school and on weekends, adn hope to have the Humvee retrofitted and fully operational by next April. They also presented their research at the recent Society of naval Engineers convention at Bloomington, Indiana. The project has garnered strong community support from area industries, which supplied tools, equipment and parts.
Teacher Ray Niehaus believes that hsi student will benefit for years to come. "It puts them on the leading edge of battery and electric technology, and in the forefront when they go to college." Pike Central is an active participant in Project Lead the way, a national project and program-based education curriculum to promote careers in engineering.

HUMVEE PROJECT PLAN
HUMVEE PROJECT PLAN
We have decided to go with the 3 clutch 2 motor/generater idea proposed at a meeting we had with Crane and Indy Powers. The team has also decided to scale down to a 4 cylinder engine and would like to go down to a smaller transmission if possible. We currently have space to fit 14 of the 11" x 6" x 12" lithium ion titanate batteries, but we don't have room for the Enerdel. We also would like to look into flat batteries to convert the humvee bed cargo space, then place a steel plate on the batteries to prevent crushing them. Then they will add the same amount of steel to the wheel well tops to make the bed taller. Our timeline is included and is only a estimated plan.HUMVEE PROJECT TIMELINE

Five Students from the HEV Wraith team went to the ASNE Conference in Bloomington, IN. ASNE stands for American Society Naval Engineers. The conference is held every two years at the Bloomington Convention Center. C.M. Brown, Anna Woolery, Brandon Bohnert, Travis Wood, and Alex Morton attended under the supervision of Mr. Ray Niehaus. We had a booth set up with information about what we are doing in the Project Lead the Way program. We also had a presentation set up about the HEV Wraith Project. We talked to numerous people from different organizations from across the country and even over seas. Visitors of the booth could not believe that a high school is working on a project of this magnitude.
The students that are working on the H.E.V. Wraith Project are: Alex Morton Brandon Bohnert, Damon Steltenpohl, Anna Woolery, Josh Steineker, C.M. Brown, Richard Newkirk, Jeff Estey, Emily Burns, Ethan Smith, Josh Greenwell, Dustin Morton, Travis Wood, BreAnn Lane, Eric McCord, Josh Stieneker, and Ian Dudenhoeffer.
The name of the project is H.E.V. Wraith H.E.V. stands for Hybrid Eclectic Vehicle and a Wraith is an evil specter. We are currently calculating the horse power, RPM, and gear ratios. Everything we are calculating must be precise to get the Humvee to run with perfection. We have also decided to change the Humvee from the 8 cylinder to a 4 cylinder engine. We are converting the Humvee to electric as well, and will be using a new type of battery called a Lithium-Ion Titanate battery that does not have thermal events. A thermal event happens when a battery is pierced causing it to rupture. When ruptured, a battery will blow up causing battery acid to be shot out which is very hazardous. The drive-train design involves a four cylinder engine with a driveshaft running through an electrically actuated clutch connecting to a generator/motor running through another electric clutch connecting to a motor/generator through a final electric clutch through the transfer case into the rear axel driving the vehicle. The generator/motor is an electric motor that when turned produces power and can double as a motor if necessary. The motor/generator is the main drive motor but like the generator/ motor it can double as a generator if necessary. Right now the military pulls a generator trailer behind the Humvee, so we want to make it a generator itself to run lights, welders, etc. off of the batteries. We will also be trying to exceed what the maximum battery capacity that is currently in other hybrid Humvee prototypes. Our goal is to be able to exceed forty miles out and back running only on battery power. This means that the military wants to be able to drive to their destination running on battery power and back to their base. We are also trying to exceed fifty miles per hour or highway speed running on electric power. We chose this design over other options because it is most feasible for a military purpose and because it meets the constraints that were given to us. The purpose of the project is not only to increase the fuel mileage but to create a kit to retrofit existing Humvees over to this system. We want to be able to ship the kits across seas to military bases so that the new systems can be bolted to the existing Humvees with as little cutting and modifying to the original chassis as possible.
Right now we are working on the project plan, and will be removing the eight cylinder engine soon. John Melhiser is allowing us to rent the service station, across from the Do It Best hardware store in Petersburg, to work on the Humvee. We have had several meetings for the Humvee recently include meetings with Crane Naval Base, Indy Powers, and Solar Sources. We want to tie the community into the project as much as possible, and several of the components we will be using are manufactured in Indiana.
We plan to have the project completed in twelve to fourteen months. We are trying to move as quickly as possible, but there is a lot of research and planning involved, such as deciding on the kind of engine that we will be using, where we will be storing the batteries in the Humvee, and the kind of motors and electric clutches, just to name a few things. We would like to thank Scott Willis, Dave Sabotka, John Schneider, Chuck Steltenpohl, Steve Tolen, Jerry Hargus, Crane, Indy Power Systems, Enerdel Battery, GM Remy, Cummins, Solar Sources, and Altiarnano Battery for the help we have received from them.

This week the team is looking up different web sites. They have mostly been looking at Energel Batteries, Power Films, and Indy powers. Right now they are waiting on tools so they can get their hands dirty and start really working. Pike Central High School has moved the Hummvee to the bus barn in order for the team to work on it. They have begun to re
search transmission types, Electrical motors, and power sources. Steve Tolen of Indy Power Systems and he has offered to give them a Lithium Energel Battery, the switching system and any other help they need.Top- Incoming sophmores look at Humvee
