Technical report on the fabrication of a fan blade

32 PAGES (4200 WORDS) Mechanical Engineering Paper
ABSTRACT
In recent times, most of the household appliances are using electric power and as such, electricity shortage has become a major problem throughout the world. Ceiling fan is one of such appliances that consume electric power. The best way to minimize the power consumption of the ceiling fan is to reduce the weight of the ceiling fan blade. Thus, this project work entails the design of a new ceiling fan blade in which case the weight and power consumption was compared to the Panasonic model ceiling fan blade. The new ceiling fan blade was designed and fabricated and when compared to the conventional blade, it saves 35% power consumption and weight reduction of 28%.
