Sikorsky S-19

Sikorsky S-19 is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Sikorsky S-19 rather than just read about it. In short: The Sikorsky S-19 was a Russian twin-engine experimental prototype biplane aircraft built late in 1916 by the Russian Baltic Railroad Car Works while Igor Sikorsky was chief engineer of the aircraft manufacturing division. Design and development The S-19 was a two bay biplane powered by two 150 horsepower (112 kilowatts) Sunbeam Crusader water-cooled V-8 engines installed in a push-pull configuration.

Key takeaways

Sikorsky S-19 belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Sikorsky S-19 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Sikorsky S-19 from memory before moving on to harder problems.

Reference excerpt

The Sikorsky S-19 was a Russian twin-engine experimental prototype biplane aircraft built late in 1916 by the Russian Baltic Railroad Car Works while Igor Sikorsky was chief engineer of the aircraft manufacturing division.

Design and development The S-19 was a two bay biplane powered by two 150 horsepower (112 kilowatts) Sunbeam Crusader water-cooled V-8 engines installed in a push-pull configuration. Arranged as a twin-boom aircraft, it had a large rudder located in the center of the empenage. Two crew members occupied cockpits in the forward-most section of the booms in front of the lower wing and served as pilot and machine gunner. Flight testing revealed sluggish performance and the aircraft was scrapped after a minor crash.

Worked examples

Example 1 — a first encounter with Sikorsky S-19

Start with the simplest possible case. Write down what Sikorsky S-19 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Sikorsky S-19 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 Sikorsky S-19 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 Sikorsky S-19

In research: Sikorsky S-19 appears in science 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 Sikorsky S-19 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: Sikorsky S-19 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1910s Russian military aircraft, Aircraft first flown in 1916, Biplanes, so understanding it makes those chapters shorter.
In everyday life: Look for Sikorsky S-19 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.
