Project details

Drexel University's Department of Mechanical Engineering and Mechanics presents the 2007-2008 Dragon Wagon project. The Dragon Wagon is a senior design project being undertaken by fifteen Drexel University undergraduate students under the advisement of Dr. Bradley Layton. While the Senior Design project ended in June of 2008, the Dragon Wagon has continued to enjoy ongoing use and development. Thanks to the hard work and determination of a 2009 Freshman design team, the Dragon Wagon competed successfully in the 2009 ASME HPVC race in Philadelphia. Currently, the Dragon Wagon is undergoing some transmission redesign and electronics redesign as a group of students prepares it for a ride from Drexel University to Central Connecticut State University via the East Coast Green way, in order to compete at the 2010 ASME HPVC East race!

Goals

The Dragon Wagon project aims to create low-cost, zero-emissions alternatives to the automobile, specifically for use in urban environments. Our first vehicle utilizes both the power of its two human passengers and a high-efficiency electric motor to do the following:

• Accelerate the vehicle from 0 - 35 mph in time comparable to that of a traditional automobile.
• Maintain a top speed of at least 35 mph.
• Have a braking distance comparable to that of a traditional automobile.
• Have a turning radius comparable to that of a traditional automobile.

The result of satisfying these four criteria is a vehicle that can fully integrate with urban traffic.

Environmental impact

In an urban environment, the Dragon Wagon can transport you wherever a traditional automobile can drive in the same amount of time, with the following benefits:

• The Dragon Wagon does not run on gasoline, or any other fossil fuels.
  • A sustainable transportation alternative!
• The Dragon Wagon is energy efficient.
  • Lightweight construction and high-end components mean that minimal energy is needed to operate.
• The Dragon Wagon is emissions free. No combustion engine.
  • Reduces carbon emissions, reduces air pollution, helps fight global warming!
• The Dragon Wagon is less than half the size of an automobile.
  • Helps reduce urban congestion! Fits in a bike lane!

Societal impact

The Dragon Wagon does not look like a traditional automobile. Driving around in the Dragon Wagon turns heads — everyone wants to know what you are driving. This attention-grabbing aspect of the vehicle helps raise awareness of green alternatives to transportation and arouses interest in the field.

The Dragon Wagon requires you to pedal the vehicle to operate at its peak performance. This helps to promote physical activity in a society where many simply do not have the time to work out on a daily basis. If used for your daily commute, you will receive your daily dose of exercise. Not only will you be helping the environment, you will be helping your health and well-being as well!
