Reference excerpt

The Sukhoi Su-80 (formerly known as the Sukhoi S-80) is a Russian twin-turboprop, twin-boom STOL transport aircraft.

Design and development The Su-80 program was supposed to start in the late 1990s, but due to lack of funds, it was postponed for several years. A prototype of the combined Freight/Passenger Su-80GP was built and its first flight was planned for early 1998, but the program was delayed again. The first flight of the prototype was at the 2001 MAKS in Moscow issued Zhukovsky. On 4 September 2001, Igor Wotinzew started with the prototype, 82911, on his first flight. In early 2006, the Su-80 entered production in the KnAAPO factory in Komsomolsk-on-Amur. The first model of the turboprop transporter Sukhoi S-80 was shown at the 46th Paris International Air and Space Show, 2005. The plane is being developed by Sukhoi OKB and the aircraft factory in Komsomolsk/Amur under the "konversija" program. The aircraft is intended to replace the An-24/26, An-28 and Yak-40, and to compete with the Antonov An-38 . The design of the machine is very similar to the Scaled Composites ATTT and the Rockwell OV-10. It has three lift-generating surfaces: the primary wings; two fins at the rear of the fuselage which join the booms to the fuselage; and the horizontal stabilizer which joins the two vertical fins at the rear of the booms. Two General Electric CT7-9B turboprop engines are housed in bays at the front of the tail booms. The sleek hull offers space for 30 passengers, and a "beaver-tail" cargo ramp is fitted at the rear of the fuselage, which allows for easy loading and unloading of cargo.

Operational history Eight aircraft from the second production (first definitive) batch were earmarked for delivery to customers.

Commercial orders Blagoveshchensk Airlines, Chukotavia, Dalavia, the Petropavlovsk-Kamchatsky Air Enterprise, and Polar Airlines all signed preliminary agreements to acquire the type. The KnAAPO factory airline was expected to be the Su-80's first operator.

Military orders The Kazakhstan Border Guards tentatively ordered ten Su-80s, while the Chinese People's Liberation Army Air Force, Jordanian Air Force, Royal Malaysian Air Force, Indonesian Air Force and Republic of Korea Air Force all expressed interest. Ultimately, no aircraft performed active service. In 2022, it does not appear that any of these aircraft are operational.

Variants There are two different models of the Su-80. The four pre-series aircraft were of a short-fuselage design, while the fifth, sixth and seventh prototypes were stretched by 1.4 m (4 ft 7 in) allowing an extra row of passenger seats.

Worked examples

Example 1 — a first encounter with Sukhoi Su-80

Start with the simplest possible case. Write down what Sukhoi Su-80 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 Sukhoi Su-80 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 Sukhoi Su-80 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 Sukhoi Su-80

In research: Sukhoi Su-80 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 Sukhoi Su-80 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: Sukhoi Su-80 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2000s Russian airliners, 2000s Russian civil utility aircraft, Aircraft first flown in 2001, so understanding it makes those chapters shorter.
In everyday life: Look for Sukhoi Su-80 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.
