Triple expansion engines, whereby the steam is expanded three times, provided the power of most of the world's ships until supplanted by turbines in warships and fast passenger ships in the period 1910 - 1920. They still powered much of the world's cargo ships and ferries until the 1950's. They power such famous ships as the Titanic, the Liberty ships, and Sydney's own Lady Hopetoun, South Steyne and John Oxley. Chosen for their economy over compound engines they were were rare in small sizes (less than around 60 IHP). With six power strokes per revolution they are extremely smooth in operation. Most of the large triples ran slowly. The Titanic's two reciprocating engines running at 76rpm each developed 16,000IHP. The Lady Hoptetoun's 260IHP engine runs at 250rpm. This small triple is designed to produce 10IHP at 300rpm. Although relatively small in horsepower the engine produces a lot of torque, the equivalent of a five litre 300HP V8 in a modern car. |
