Reference excerpt

The Yakovlev Yak-58 is a small, multi-role utility transport and business aircraft. The aircraft features a pusher engine and twin boom tail. It saw limited production in the late 1990s.

Design and development Following the collapse of the Soviet Union, as military contracts evaporated, the Yakovlev design bureau was forced to convert to designing civilian aircraft to stay in business. Their first post-Soviet design was the Yak-58, a small multi-role utility transport designed to appeal to as many prospective buyers as possible. The Yak-58 is a low-winged monoplane of pusher configuration, powered by a Vedeneyev M14PT radial engine mounted at the rear of the fuselage nacelle, driving a three-bladed propeller. Rather than conventional tailbooms, the two highly swept fins were mounted directly to the wing, and were joined by the tailplane. The undercarriage is a retractable tricycle arrangement. Seats are fitted for a pilot and five passengers, with the option of replacing the passengers by 450 kg (990 kg) of cargo.

Testing The first prototype made its maiden flight at Tbilisi, Georgia on 26 December 1993, although some sources state that the first flight did not occur until 17 April 1994. This aircraft was wrecked in a fatal crash at the ILA Berlin Air Show on 27 May 1994, with the second prototype flying on 10 October 1994. Yakovlev claimed in 1997 that it had orders for 250 Yak-58s, with an ELINT version and a version replacing the radial engine with a turboprop planned. Limited production occurred at Tbilisi, however, due to funding problems and political problems between Georgia and Russia, Yakovlev attempted to restart the project in 2003, possibly with production moved back to Russia.

Worked examples

Example 1 — a first encounter with Yakovlev Yak-58

Start with the simplest possible case. Write down what Yakovlev Yak-58 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 Yakovlev Yak-58 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 Yakovlev Yak-58 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 Yakovlev Yak-58

In research: Yakovlev Yak-58 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 Yakovlev Yak-58 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: Yakovlev Yak-58 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1990s Soviet and Russian civil utility aircraft, Aircraft first flown in 1993, Low-wing aircraft, so understanding it makes those chapters shorter.
In everyday life: Look for Yakovlev Yak-58 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.
