The propeller

When ships were powered by steam engines during the 1800s communications on the seas became faster and more reliable. The first steamships that sailed across the Atlantic were paddle-steamers with sails as a backup.

The Swedish inventor, John Ericsson´s first propeller imitated the feet of sea birds and was called the goosefoot propeller. In 1836 he took out a patent on a new design which was equipped with blades that were mounted in a circle. It was significantly better.

Today we still use the type of propeller, which was developed, in the mid-1830s, but in many different variations. Large ships often have propellers with strong curved blades which enable them to cut smoothly through the water. In this way propeller power is more efficient.
