Campbell Diagram of a steam turbine. Analysis shows that there are well-damped critical speed at lower speed range. Analysis shows that there are well-damped critical speed at lower speed range. Another critical speed at mode 4 is observed at 7810 rpm (130 Hz) in dangerous vicinity of nominal shaft speed, but it has 30% damping - enough to ...
A steam turbine locomotive engine is a steam locomotive driven by a steam turbine. The first steam turbine rail locomotive was built in 1908 for the Officine Meccaniche Miani Silvestri Grodona Comi, Milan, Italy. In 1924 Krupp built the steam turbine locomotive T18 001, operational in 1929, for Deutsche Reichsbahn.
Engine designers had always been aware of the many limitations of the rotary engine, so when static style engines became more reliable and gave better specific weights and fuel consumption, the days of the rotary engine were numbered. Rotary engines had a fundamentally inefficient total-loss oiling system. In order to reach the whole engine ...
These diagrams were used to determine the efficiency of steam engines, such as those found aboard Western Rivers steamboats. Reason This image is of high technical standards, sufficient scalable resolution, is an excellent illustration of the related concepts, has a free license, supplements two separate articles, is accurate, has valuable ...
To change this template's initial visibility, the |state= parameter may be used: {{Steam engine configurations | state = collapsed}} will show the template collapsed, i.e. hidden apart from its title bar. {{Steam engine configurations | state = expanded}} will show the template expanded, i.e. fully visible.
A steam-powered aircraft is an aircraft propelled by a steam engine. Steam power was used during the 19th century, but fell into disuse with the arrival of the more practical internal combustion engine at the beginning of the pioneer era. Steam power is distinct from its use as a lifting gas in thermal airships and early balloons.

Libralato engine. A pistonless rotary engine is an internal combustion engine that does not use pistons in the way a reciprocating engine does. Designs vary widely but typically involve one or more rotors, sometimes called rotary pistons. Although many different designs have been constructed, only the Wankel engine has achieved widespread adoption.
