What improved?
Turbine blades turn continuously as steam flows through them. The propulsion machinery needs no back-and-forth pistons or connecting rods.

THE ENGINE’S STORYSteam without pistons
Where have the pistons gone? Turbinia used steam turbines instead. Steam flows through rows of blades and keeps their shafts spinning. The shafts turn propellers under the ship. Launched in 1894, this little vessel amazed crowds at a naval review in 1897 and helped change how ships were powered.

Read the source Her machinery changed during development. The model follows the three-shaft, nine-propeller arrangement of 1897. Modern photographs show the preserved ship, not an unchanged operating vessel.
Choose one moment in history
Turbinia launched in 1894 and her machinery changed during development. This exhibit follows the three-turbine, nine-propeller arrangement used for the famous 1897 demonstration.
A new age of ships
The demonstration helped show what steam turbines could do at sea. Marine engineers still had to solve problems such as cavitation: vapour bubbles forming around fast propeller blades.

THE ENGINEER’S CHALLENGE
CHIEF ENGINEERThe demonstration voyage
- 1. Learn the job
- 2. Put it in order
- 3. Take the controls
Show what a turbine-powered ship can do. Steam turns blade rows continuously; shafts carry that turning motion to the propellers.
Your goal
Pass three trials while avoiding the cavitation zone.
First, discover how the engine works by choosing the steps in order. Then adjust three controls for each round. You can try again, ask for help, or restart at any time.
