Why Are Ship Propellers So Small?
Why do massive ships have such small propellers? What seems like a simple design choice is actually one of the most precise engineering decisions in the world. This video explores the invisible physics limit that prevents propellers from growing endlessly — and how crossing that boundary can silently destroy one of the most expensive machines on Earth.
You’ll discover how cavitation — a phenomenon caused by extreme pressure changes — creates millions of microscopic explosions that slowly eat away at solid metal. You’ll also learn why making a propeller bigger doesn’t always increase power, and how even a few extra centimeters can reduce efficiency, increase fuel consumption, or lead to catastrophic failure.
This is a story about hidden physics, extreme naval engineering, and the fragile balance between power and self-destruction that keeps global shipping moving every day. If you enjoy engineering mysteries, ship technology, and the science behind massive machines, this video is for you.
