Pyotr Grushin

Pyotr Grushin 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 Pyotr Grushin rather than just read about it. In short: Pyotr Dmitrievich Grushin (Russian: Пётр Дмитриевич Грушин, January 15, 1906, Volsk, Russian Empire – November 29, 1993) was a Soviet rocket scientist and, from 1966, an academician of the Academy of Sciences of the USSR. Grushin graduated from Moscow Aviation Institute, where he participated in the development of the Stal-MAI aircraft (Russian: Сталь-МАИ, 1931–1934).

Key takeaways

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

Reference excerpt

Pyotr Dmitrievich Grushin (Russian: Пётр Дмитриевич Грушин, January 15, 1906, Volsk, Russian Empire – November 29, 1993) was a Soviet rocket scientist and, from 1966, an academician of the Academy of Sciences of the USSR. Grushin graduated from Moscow Aviation Institute, where he participated in the development of the Stal-MAI aircraft (Russian: Сталь-МАИ, 1931–1934). Later, he became a chief designer of KB MAI (1934–1940), where he developed the light bomber BB-MAI and some other designs.[1] His later designed the heavy long-range fighter IDS (Russian: ИДС), later renamed Gr-1 after Grushin. The plane made its first flights in 1940-1941 at Kharkov Aviation Plant (KhAZ) 135 (with Grushin as a Chief designer of KhAZ OKB), but after the war began it was destroyed in an air raid. He worked as the Chief engineer on Plant 21 and later as vice chief designer to Lavochkin at his Lavochkin design bureau. He was the chief developer of a number of air defence systems at KB Fakel (former OKB-2) located in Khimki. This design bureau now bears his name. For the design of the V-750 missile, the interceptor component of the S-75 Dvina air defense system, Grushin was awarded the Hero of Socialist Labour in 1958. This missile downed U-2 spy-plane of Francis Powers on May 1, 1960 near Sverdlovsk. In 1981 he received his second Hero of Socialist Labour award for the S-300 missile system. He was a laureate of the Lenin Prize (1963), and held 7 Orders of Lenin, among other awards.

Worked examples

Example 1 — a first encounter with Pyotr Grushin

Start with the simplest possible case. Write down what Pyotr Grushin 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 Pyotr Grushin 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 Pyotr Grushin 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 Pyotr Grushin

In research: Pyotr Grushin 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 Pyotr Grushin 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: Pyotr Grushin is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1906 births, 1993 deaths, Burials at Novodevichy Cemetery, so understanding it makes those chapters shorter.
In everyday life: Look for Pyotr Grushin 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.
