ARIA 2008
The First Vehicle Designed & Constructed by IUT Supermileage Team

This project has started since April 2007. The most important concept in designing and building the vehicle was to optimize the fuel consumption. In other hand it was tried to obey the rules of 2008 Shell Eco-Marathon competition.

This is a brief description for the ARIA:

• Year of the project: 2007-2008
• Length: 2950mm
• Height: 670 mm
• Width: 750 mm
• Net Weight: 34 kg
• Engine: A modified Single Cylinder Honda GX35 - Fuel Injection System - Max. Of RPM: 7000 - 2hp power – Max of torque: 2 N.m – Volume: 148 cc – compression ratio: 8:1 – Modeled and analyzed by the GT Suite software.
• Transmission System: CVP hub with a continuous range of gear ratios between 0.5 and 1.75 which makes the driver able to change the gear ratio when he wants and how much he wants. The power is coming from the engine to the driver wheel via a chain and sprocket mechanism and multiplied by the ratio the driver determined by the CVP manual control switch.
• Frame: An Al.7075 structure – 8 kilograms – Constructed by TIG welding – Structural analysis in ANSYS software.
• Body: Drag coefficient: 0.12 Calculated with ANSYS CFX software – 3 layers of Carbon Fiber constructed by a hand CMM process for the mold. The mold is made from MDF sections with just 16 mm of thickness.
• Equipped with a monitoring system to display the fuel consumption at any moment.
• Adjustable steering system which made the driver able to select his/her desire position. Modeled and analyzed by MSC ADAMS and SIM Designer Software.

This vehicle was presented in 2008 Shell Eco-Marathon event. It was candidate for the 2 special awards: ECO-Conception and Technical innovations awards but did not win these awards finally.

Although fortunately the team has won the social activity award which related to some management affairs and moderating the team at Nogaro motor circuit and the presentations have presented by the team members. It was a satisfactory result as the first experience.
