Flapping Wing

Throughout Leonardo da Vinci's life he envisioned humans flying through emulation of birds and other flying creatures. He translated the fluid motion of birds to moving parts, simple machines, and flexible joints. Using mostly wood, rope, iron, and animal skin da Vinci attempted to make his dream a reality. It is your group's goal to reverse engineer as many [da Vinvi] flapping wing documents you can locate in order to develop a manufacturable product. Begin by using your knowledge of the design process to develop ideas, rough sketches, and 3D computer models. Throughout the process it is necessary to develop Ideal Mechanical Advantages (IMA) of individual simple machines and gears in order to find the overall IMA based on projected dimensions. Once your group has developed an approved system you will then attempt to implement an electric drive system, based on your knowledge of power, torque, angular velocity, and digital electronics.

Replace SMET with Leonardo Da Vinci Machines LDVM!

Attention POE students!

First project of the year: Analyze the amazing inventions of Leonardo Da Vinci in order to develop small scale working models.

Questions:

What are the six simple machines?

What do you know about Mechanical Advantage, Gears and ratios?

What process should you follow in order to successfully complete design?
