Pyotr Dolgov

Pyotr Dolgov is a physics 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 Dolgov rather than just read about it. In short: Pyotr Ivanovich Dolgov (Russian: Пётр Иванович Долгов; 21 February 1920 – 1 November 1962) (Hero of the Soviet Union) was a colonel in the Soviet airborne forces. Dolgov died while carrying out a high-altitude parachute jump from a Volga balloon gondola.

Key takeaways

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

Reference excerpt

Pyotr Ivanovich Dolgov (Russian: Пётр Иванович Долгов; 21 February 1920 – 1 November 1962) (Hero of the Soviet Union) was a colonel in the Soviet airborne forces. Dolgov died while carrying out a high-altitude parachute jump from a Volga balloon gondola.

Early life and career Dolgov was born into a family of farmers in the village of Bogoyavlenskoye (now Dolgovo) in Zemetchinsky District, Penza Oblast. He served with the Soviet airborne in World War II. In January 1945, Dolgov became a company commander in the 350th Guards Rifle Regiment of the 114th Guards Rifle Division. Dolgov participated in the Budapest Offensive and the Vienna Offensive. On 6 April, Dolgov reportedly knocked out a self-propelled gun and killed 40 German soldiers. He was wounded but allegedly refused to leave the battlefield. Dolgov graduated from the Ryazan Higher Airborne Command School in 1947. He worked as a parachute tester. He made 1409 jumps, setting eight world and Soviet records. He reportedly designed the ejection seats for the Vostok spacecraft.

Death On 1 November 1962, Dolgov and Major Yevgeni Nikolayevich Andreyev ascended in a Volga balloon gondola from Volsk, near Saratov, to make high-altitude parachute jumps. Andreyev successfully completed his jump. Dolgov, testing an experimental pressure suit, jumped at 28,640 metres (93,960 ft). The helmet visor of Dolgov's pressure suit hit part of the gondola as he exited, and the suit depressurized, killing him. On 12 December 1962, Dolgov was posthumously named a Hero of the Soviet Union. If Dolgov's jump had been successful, he still would not have exceeded the record set by Joseph Kittinger for the highest-altitude parachute jump in history (31,300 metres (102,700 ft), 16 August 1960). The current world record is held by Alan Eustace (41,425 metres (135,909 ft), 24 October 2014).

Legacy At the time of Dolgov's death, the Soviet Army newspaper Red Star announced that he had died in the course of "carrying out his duties". Over the years there have been false reports that Dolgov actually died on 11 October 1960, in a failed flight of a Vostok spacecraft. A fictionalized version of Dolgov's death (incorrectly dated in February 1961) appears in the short story "The Chief Designer" by Andy Duncan, which was published in Asimov's Science Fiction magazine and was a Hugo finalist.

Worked examples

Example 1 — a first encounter with Pyotr Dolgov

Start with the simplest possible case. Write down what Pyotr Dolgov claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, 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 Dolgov 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 Dolgov 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 Dolgov

In research: Pyotr Dolgov appears in physics 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 Dolgov 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 Dolgov is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1920 births, 1962 deaths, Accidental deaths in the Soviet Union, so understanding it makes those chapters shorter.
In everyday life: Look for Pyotr Dolgov 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.
