Reference excerpt

The Kolesnikov-Tsybin KC-20 or KTs-20 (Russian: КЦ-20) was a Soviet light troop military glider of World War II.

Development Shortly after the German attack in 1941, Soviet headquarters realized a need for transport gliders and ordered the development of several designs. The biggest was a design of Dmitry Kolesnikov and Pavel Tsybin, although it was still a light glider. Two prototypes were built in October 1941. It was ordered for production, under the designation KC-20 (or KTs-20) for designers' initials and the number of troopes carried. 68 were built in 1942-1943. They were produced in a wood industry works in Lopatino village near Kazan. The KC-20 was the biggest, but least numerous of Soviet transport gliders. It could transport 20 troops or up to 2200 kg of cargo. It was quite successful, its major drawback was a lack of a big cargo hatch, therefore guns could by only carried in parts. It was initially planned to fit the glider with a back machine gun turret, hence double tailfin, but the plan was abandoned.

Operational history Like Antonov A-7 and Gribovski G-11, they were mainly used for supplying Soviet partisans with provisions, weapons, equipment and trained men, in night flights. The most intensive use was from April to November 1943 in Belarus, in the Polotsk-Begoml-Lepel area. After landing, gliders were destroyed and pilots were sometimes taken back by aircraft. They were also used to transport sabotage groups behind enemy lines. KC-20s were towed mainly by DB-3 bombers. A less typical action was an air bridge from Moscow to the Stalingrad area in November 1942, in order to quickly deliver antifreeze cooling liquid for tanks, during the battle of Stalingrad.

Description High-wing, wooden construction glider, with a double tailfin. Slim fuselage, semi-monocoque, rectangular in cross-section. Pilot's cab in front, behind it, a transport compartment. There were double doors on both sides, and several small rectangular windows. Landing gear was manually retractable, in order to shorten landing, the glider could land on a skid under a fuselage.

Worked examples

Example 1 — a first encounter with Kolesnikov-Tsybin KC-20

Start with the simplest possible case. Write down what Kolesnikov-Tsybin KC-20 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 Kolesnikov-Tsybin KC-20 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 Kolesnikov-Tsybin KC-20 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 Kolesnikov-Tsybin KC-20

In research: Kolesnikov-Tsybin KC-20 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 Kolesnikov-Tsybin KC-20 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: Kolesnikov-Tsybin KC-20 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1940s Soviet military transport aircraft, 1940s military gliders, Aircraft first flown in 1941, so understanding it makes those chapters shorter.
In everyday life: Look for Kolesnikov-Tsybin KC-20 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.
