Yakovlev Yak-201

Yakovlev Yak-201 is a science 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 Yakovlev Yak-201 rather than just read about it. In short: The Yakovlev Yak-201 was a planned Russian vertical takeoff and landing stealth fighter/interceptor aircraft for the Russian Navy, as a follow-up to the Yak-141 and Yak-43 aircraft. The design was carried out in the mid-1990s Yakovlev Design Bureau.

Reference excerpt

The Yakovlev Yak-201 was a planned Russian vertical takeoff and landing stealth fighter/interceptor aircraft for the Russian Navy, as a follow-up to the Yak-141 and Yak-43 aircraft. The design was carried out in the mid-1990s Yakovlev Design Bureau. The project was cancelled and no prototype was built due to a lack of funds and interest by the Russian Ministry of Defense.

Development The design was started on an initiative basis by the Yakovlev bureau officers in the mid-1990s to allow the Russian Navy aircraft carriers to operate state-of-the-art vertical takeoff and landing aircraft. After the Yak-141 and Yak-43 were developed, the engineers from the Yakovlev Design Bureau proceeded to the Yak-201. In 1996–1997, the aircraft was offered to the customer, but the project remained unclaimed, primarily for financial reasons, and also due to the lack of certainty of the Russian Ministry of Defense under the LFI program. No full size mock-up nor prototype were built. On 23 November 2017, it was reported that Yakovlev would be the designer to build a vertical takeoff and landing aircraft to be used on the future Russian aircraft carrier, such as the Project 2300 Shtorm or Project 11430E Lamantin carrier proposals. It may or may not be based on the Yak-201. Yakolvev might built a new vertical takeoff and landing fighter for the two 44,000-ton Project 23900 Ivan Rogov amphibious assault ships currently under construction.

Design The aircraft was supposed to differ from Yak-141 / Yak-43 by an increased range, a single engine and stealth characteristics. The aircraft is made according to the traditional scheme with two-tails, and a large angle of inclination. The plane is relatively stealthy, as it is made unobtrusive with few right angles. According to preliminary data from the bureau, the interceptor fighter was supposed to have only one pilot. The design was for a single lift-propulsion motor with a mechanical drive to a lifting fan installed behind the cockpit. The nozzle of the main engine was supposed to be vectorable. Flat and round nozzle options were considered. The ability to change the thrust vector makes the aircraft supermanoeuvrable. The armament was to be placed in an internal weapon bay inside the fuselage. The aircraft was expected to reach a speed of 1,250 km/h near the ground, and 1,800 km/h at altitude. The practical ceiling for the Yak-201 is 15,000 m. Among the armament, it was decided to use a GSh-301 rifle cannon with 120 rounds of ammunition, and to install air-to-air type R-77 long-range or medium-range at four points of suspension. The installation of short-range missiles R-73 and R-60 and NAR units with a caliber of up to 240 mm were worked out.

Worked examples

Example 1 — a first encounter with Yakovlev Yak-201

Start with the simplest possible case. Write down what Yakovlev Yak-201 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-201 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-201 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-201

In research: Yakovlev Yak-201 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-201 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-201 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1990s Russian fighter aircraft, Abandoned military aircraft projects of Russia, VTOL aircraft, so understanding it makes those chapters shorter.
In everyday life: Look for Yakovlev Yak-201 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.
