Abstract

Solar cars are powered by the sun's energy. The main component of a solar car is its solar array. which collect the energy_ from the sun and converts it into usable electrical energy. The solar cells collect a portion of the sun · s energy and store it into the batteries of the solar car. Before that happens. power trackers converts the energy collected from the solar array to the proper system voltage. so that the batteries and I the motor can use it. After the energy is stored in the batteries. it is available for use by the motor & motor controller to drive the car. The motor controller adjusts the amount of energy that flows to the motor to correspond to the throttle. The motor uses that energy to drive the wheels. Basically, normal solar car uses that energy to drive the wheels but for this project the author had a different concept. The concept is the solar car will driven by a propeller. That's mean the motor uses that energy to rotate the propeller. Then, the propeller will drive the wheels. The theory is same with others application transportation such as hovercraft and swamp boat. The propeller will give a thrust force to drive the solar car but it depends on other criteria. The criteria are how much thrust force compares with the weight of a solar car, the motor's speed, torque rotation and others. In chapter 2 will discuss about solar cells, how's it work and relates to solar car. Chapter 3 is more about design a solar car including the design process, aerodynarrucs and others. Systems considerations such as electrical systems, mechanical systems and drive controls will be discuss on chapter 4. Then, chapter 5 is about electric motor and other considerations such as the purpose and selecting the suitable motor. Propeller systems including momentum theory, aerodynamic characteristics, blades and others are on chapter 6. Chapter 7 shows the experiment analysis with graph and calculation to get the thrust force. Lastly, a model solar car with propeller on chapter 8 is built to prove that this project is realized.
