Reference excerpt

Viktor Kaplan (27 November 1876 – 23 August 1934) was an Austrian engineer and the inventor of the Kaplan turbine.

Life Kaplan was born in Mürzzuschlag, Styria, Austria into a railroad worker's family. He graduated from high school in Vienna in 1895, after which he attended the Technical University of Vienna, where he studied mechanical engineering and specialised in diesel engines. From 1900 to 1901 he was drafted into military service in Pula. After working in Vienna with a specialisation in motors, he moved to the German Technical University in Brno to conduct research at the institute of civil engineering. He spent the next three decades of his life in Brno, and nearly all his inventions and research are connected with his professorship there. In 1913 he was appointed head of the institute for water turbines. In 1912 he published his most notable work: the Kaplan turbine, a revolutionary water turbine that was especially fitted to produce electricity from large streams with only a moderate incline. From 1912 to 1913 he received four patents on these kinds of turbines. In 1918 the first Kaplan turbine with 26 kW power and a diameter of 60 cm was built by the Storek construction company for a textile manufacturer in Lower Austria. This turbine was used until 1955 and today is exhibited at the Technisches Museum Wien. After the success of the first Kaplan turbines they started being used worldwide and remain one of the most widely used kinds of water turbines. In 1926 and 1934 Kaplan received honorary doctorates. He died of a stroke in 1934 at Unterach am Attersee, Austria. Kaplan was honored and featured on the 1000 Austrian schilling banknote in 1961.

Worked examples

Example 1 — a first encounter with Viktor Kaplan

Start with the simplest possible case. Write down what Viktor Kaplan claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Viktor Kaplan before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Viktor Kaplan ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Viktor Kaplan

In research: Viktor Kaplan appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Viktor Kaplan in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Viktor Kaplan is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1876 births, 1934 deaths, 20th-century Austrian inventors, so understanding it makes those chapters shorter.
In everyday life: Look for Viktor Kaplan outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
