Vladimir Vakhmistrov

Vladimir Vakhmistrov is a astronomy 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 Vakhmistrov rather than just read about it. In short: Vladimir Sergeyevich Vakhmistrov (Russian: Владимир Сергеевич Вахмистров) (1897–1972) was a Soviet aviation engineer who is known for creating a series of parasite aircraft projects under the common name Zveno. Life and career Vakhmistrov was born on June 27, 1897, in Moscow; his father was an office clerk.

Key takeaways

Vladimir Vakhmistrov belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Vladimir Vakhmistrov to a quantity you can measure, compute or draw — that is where exam questions come from.

Reference excerpt

Vladimir Sergeyevich Vakhmistrov (Russian: Владимир Сергеевич Вахмистров) (1897–1972) was a Soviet aviation engineer who is known for creating a series of parasite aircraft projects under the common name Zveno.

Life and career Vakhmistrov was born on June 27, 1897, in Moscow; his father was an office clerk. He graduated from the Moscow Realschule (реальное училище) in 1915. At the outbreak of the First World War, Vakhmistrov volunteered for the army and was sent to Mikhailovsky Artillery School. He was sent to the front lines in 1916 with the rank of ensign of artillery, but was soon transferred to the Imperial Russian Air Service as a pilot-observer. During the Russian Civil War, Vakhmistrov joined the Red Air Force and fought on the Volga and in Turkestan. He resumed his studies in 1921, first at Turkestan University and then at the Zhukovsky Air Force Engineering Academy. Vakhmistrov built gliders at the academy: the training AVF-8 "Condor" (1924), the AVF-22 Serpent Horynych (1925, with M. K. Tikhonravov), and Gamayun and Skif (1928, with Tikhonravov and A. A. Dubrovin). In the glider Skif during the sixth All-Union gliding competition (October 6–23, 1929, in Koktebel), pilot A. B. Yumashev set an all-Union flight altitude record for gliders of 1,520 metres (4,990 ft). From February to April 1926, Vakhmistrov and pilot M. M. Gromov tested the reconnaissance aircraft R-3 (ANT-3): the first Soviet all-metal aircraft, and the first aircraft designed by A. N. Tupolev. Aircraft of this type were subsequently used against the Basmachi movement. He graduated from the Air Force Academy in 1930, and worked at the Air Force Research Institute. Between 1931 and 1940, Vakhmistrov developed the Vakhmistrov family of composite aircraft: a TB-3 4AM-34FRN heavy bomber with I-16 fighters on a bomb suspension. This concept was the combination of several aircraft, linked rigidly (not in tow) and flying together to:

Deliver fighter planes beyond their flight range Increase the range of a heavy escort aircraft Use larger bombs than the fighter planes are capable of carrying Facilitate the take-off of an overloaded aircraft with an auxiliary aircraft. The draft of the first version of the aircraft link, later named Zveno-1 and consisting of a TB-1 bomber and two I-4 fighters, was submitted by Red Army UVVS head I. I. Alksnis in June 1931 and approved by Vakhmistrov. On December 3 of that year, Vakhmistrov (as a second pilot of the bomber) participated in the first flight tests of Link-1: a TB-1 and two I-4s. This was followed by other composite aircraft between 1932 and 1939, including five fighters. Two fighters remained optimal; in the Link TB-3 SPB composite dive bomber, two I-16s carried two FAB-250 bombs. Vakhmistrov's links were not accepted for service; in accordance with instructions from the Black Sea Fleet Air Force, however, three composite aircraft were equipped with the TB-3 SPB scheme for the bombing of Constanța and Ploiești in July 1941. A triple SPB bombed the Constanța region without losses on July 26, followed by attacks on the Cernavodsky bridge on August 10 and 13. After the successful implementation of the TB-3 SPB project, Vakhmistrov proposed several advanced Link projects: the GTS flying boat, the TB-7 heavy bomber and the MTB-2 (ANT-44) heavy flying boat; hanging fighter planes would have been the I-15bis, I-16, I-180, LaGG-3, and MiG-3. At the end of 1937, Vakhmistrov's elder brother was arrested; in March 1938, Vakhmistrov was demoted from chief designer to head of the KB-29 design team. He died in 1972, and is buried in Moscow's Vagankovo Cemetery.

Worked examples

Example 1 — a first encounter with Vladimir Vakhmistrov

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

In research: Vladimir Vakhmistrov appears in astronomy 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 Vakhmistrov 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 Vakhmistrov is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1897 births, 1972 deaths, Burials at Vagankovo Cemetery, so understanding it makes those chapters shorter.
In everyday life: Look for Vladimir Vakhmistrov 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.
