Exploring the Engineering Legacy of WWII German Fuel Cans: Abstraction and Reverse Engineering

In this insightful lesson presented by Dr. Natalie Kuldell, we delve into the reverse engineering of the iconic German Wehrmachtskanister fuel cans used during the 1930s and WWII. These innovative cans, crucial for military logistics, provide lessons in design, materials science, and historical engineering practices. By studying the past, we uncover valuable insights for modern engineering challenges. We explore the concepts of abstraction, hierarchy, and the collaboration required to engineer complex systems successfully. Join us on this journey of discovery and learning.

  1. Abstraction • Lesson 1 presented by Dr.Natalie Kuldell

  2. Reverse Engineering GermanWehrmachtskanister, 1930s Fuel Cans used by WW I British army • Leaked • Need wrench and funnel to use • “Flimsies” • Snapcap • X-marks for strength, expansion • Plastic lined • Pressed seems • “WWII JerryCans”

  3. Reverse (historical) Engineering "Study the past, if you would divine the future"-Confucius "Learn from your mistakes"-my mom

  4. Forward Engineering 238 teams of engineers 8 mainframe computers 2200 workstations Scientific understanding of materials, physics, atmosphere ~100 year history of manned flight Commercial needs (#passengers, cost, distance) Consumer data

  5. Forward Engineering Scientific understanding of materials, physics, atmosphere

  6. Forward Engineering: 154, 154, 154… Wing stress test video

  7. Abstraction Hierarchy a human invention designed to assist people in engineering complex systems Some system designers Other experts who integrate of subcomponents Some experts in electrical system wiring

  8. Abstraction Hierarchy a human invention designed to assist people in engineering complex systems • Everyone has to do their job right for the final product to work • No single person understands everything about the final product • Interfaces between layers are critically important

  9. Abstraction Hierarchy a human invention designed to assist people in engineering complex systems Assemblies of devices make a system Assemblies of parts make up devices Sequences of DNA encode “parts”

  10. Why is abstraction useful?
