Vladimir Vetchinkin

Vladimir Vetchinkin is a engineering 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 Vladimir Vetchinkin rather than just read about it. In short: Vladimir Petrovich Vetchinkin (Russian: Владимир Петрович Ветчинкин) (June 29, 1888 - March 6, 1950) was a Soviet scientist in the field of aerodynamics, aeronautics, and wind energy, Doctor of Technical Sciences (1927), Honored Science Worker of the RSFSR (1946). Biography Vladimir Petrovich was born in Kutno (then in the Russian division of Poland), the son of a Russian military officer.

Key takeaways

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

Reference excerpt

Vladimir Petrovich Vetchinkin (Russian: Владимир Петрович Ветчинкин) (June 29, 1888 - March 6, 1950) was a Soviet scientist in the field of aerodynamics, aeronautics, and wind energy, Doctor of Technical Sciences (1927), Honored Science Worker of the RSFSR (1946).

Biography Vladimir Petrovich was born in Kutno (then in the Russian division of Poland), the son of a Russian military officer. Vetchinkin graduated from Moscow Higher Technical School (MVTU) in 1915, the favorite student of Nikolay Zhukovsky and generally viewed as his successor. In 1913, they had created a vortex-sheet theory of aircraft propellers. In 1916, Vetchinkin and Zhukovsky created the aviation calculation and test bureau in the wind-tunnel laboratory of the Moscow Higher Technical School, and in 1918 he helped found the Zhukovsky Central Institute of Aerodynamics (TsAGI). He became a professor at the Zhukovsky Air Force Academy in 1923. In 1914, Vetchinkin began working with Anatoly Georgievich Ufimtsev on high performance windmills for electric power generation. Zhukovsky created a new division of wind motors in TsAGI to support this effort. They built an 8 kilowatt experimental wind generator in Kursk in 1929. To store energy during lulls in the wind, it used a 360 kilogram flywheel contained in a vacuum chamber. From 1921 to 1925, Vetchinkin lectured on the theory of rockets and space travel, and was the first to present a correct theory of interplanetary flight based on elliptical transfer orbits (an idea usually attributed to Walter Hohmann). He was a member of the Society for Studies of Interplanetary Travel. From 1925 to 1927, he worked on problems of cruise missiles and jet aircraft, and he took part in the activity of RNII (Scientific Research Institute of Jet Propulsion). Vetchinkin was a key supporter of rocketry pioneer Yuri Kondratyuk, and helped him get his work published. He died in Moscow in 1950. The lunar crater Vetchinkin, on the far side of the Moon, is named after him.

Notes

Worked examples

Example 1 — a first encounter with Vladimir Vetchinkin

Start with the simplest possible case. Write down what Vladimir Vetchinkin 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 Vladimir Vetchinkin 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 Vladimir Vetchinkin 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 Vladimir Vetchinkin

In research: Vladimir Vetchinkin 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 Vladimir Vetchinkin 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: Vladimir Vetchinkin is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1888 births, 1950 deaths, 20th-century Russian engineers, so understanding it makes those chapters shorter.
In everyday life: Look for Vladimir Vetchinkin 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.
