AIMS OF THE PROJECT

Persian Gazelle is a single-driver car with 5 length, 1.8 meters width and 1 meters height. This vehicle has 3 wheels, 2 front wheels carry Brake and Steering system, and the single rear wheel is attached to a DC in-wheel electrical motor. The motor receives its power from 30kg 4000 W Li-ion batteries, which are under charging with 8 m^2 18% efficient solar cells mounted on the top surface of the car. Vehicles weight is nearly 300 kg and the top speed as about 110 km/h. It can move about 3 hours in 60 km/h without any light starting with full charge on the flat road. The drag coefficient is about 0.2 in 100km/h and the lift coefficient is about zero. The chassis as made from steel and the body is made with carbon and glass fiber composites. The brakes are hydraulic disk brake and the steering system is rack-pinion system.

TEHRAN, May 2--Iranian students who have designed and manufactured the ’Persian Gazelle’, the Middle East’s first solar racecar, will visit Massachusetts Institute of Technology (MIT) in the United States, to participate in a world-class program to design the world’s most sophisticated solar racecars.

Mohammad Hemmati, executive manager of the University of Tehran’s solar car team, told ISNA that MIT has invited the Iranian team to take part in the project together with 20 other top teams from around the world.
“During the three-month program, all the teams will be provided with the required facilities and will share their ideas in designing the best solar racecars for future racing championships,“ he said.

He said the Persian Gazelle will be unveiled at MIT on July 10, stressing that several teams from the US, Canada, the Netherlands and Australia will also showcase their latest solar racecars at the event.
He said the Iranian team will travel to America in mid-June provided authorities at Tehran University extend necessary cooperation.

“Persian Gazelle is the first solar racecar produced in Iran and the Middle East and with a length of five meters, width of 1.8 meter and height of one meter, it can attain a speed of 100 kilometers per hour using rechargeable lithium-polymer batteries,“ he said, adding that the car weighs less than 250 kilograms.

Saturday, September 24, 2005 - 'Persian Gazelle' misses World Solar Challenge

It is unclear what has happened to the Iranian team that was supposed to participate in tomorrow's World Solar Challenge. Event director Chris Selwood says his last contact with the team was on Wednesday when they said their visas had been issued but they did not have any confirmation about airfreight.  It is believed the car might be in Dubai.

Mr Selwood says although the situation is out of his control, it is very disappointing. "That was the first solar car we would have seen out of the Middle East," he said.  "The pictures and the technical specifications that they sent us showed us that it wasn't going to be quite a credible entry and a lovely name the Persian Gazelle.  "I think it would have done wonders for international relationships to have had a car form Iran."

The University of New South Wales team may also miss the start. The team was testing its solar car on the Arnhem highway yesterday afternoon when components gave way. Mr Selwood says although the team has not given him a written declaration that it has withdrawn it has indicated it is unlikely to participate. "I think there's a few bruised egos around the place," he said. "I haven't seen the car but I have spoken to them and I think they're trying to fix it and they're quite pessimistic and don't believe that they're going to be able to qualify." The challenge starts in Darwin and ends in Adelaide.

During these competitions, students learn about solar panels, electric motors, electronics, vehicle chassis, bodywork, aerodynamics, suspension, batteries and how to solve practical problems during the design process, while working as a team.  It's demanding stuff and more fun that laying in bed watching TV, where individuals may seek inspiration, but achieve very little.
