New stage for Russian light aviation: VK-800 engine enters flight tests

Last week, the Yak-40 laboratory aircraft with the latest Russian VK-800 engine made its maiden flight. Before that, the engine had only been tested on the ground, and its takeoff marked the beginning of an important stage in the development of the domestic aviation industry.

During the test flight, temperature conditions, system tightness, and instrumentation were checked. Everything went as planned, and now the engineers are preparing for the next tests.



The VK-800 is one of the most anticipated engines in Russia. It is planned to be installed on the light aircraft LMS-901 "Baikal", which is to replace the legendary An-2. In addition, the unit is intended for the twin-engine LMS-192 "Osvey" and the training UTS-800.

The success of these projects largely depends on the reliability of the power plant, so its testing is a key step towards the revival of domestic light aviation.

Let us recall that the development of the Baikal was accompanied by difficulties for a long time. Initially, the aircraft was equipped with the American H80-100 engine from General Electric, but after the sanctions were tightened, it was decided to switch to our analogue. This required not only a redesign of the design, but also new certification procedures, which delayed the project.

However, Prime Minister Mikhail Mishustin recently ordered that serial production begin no later than the end of 2025. The Ural Civil Aviation Plant is currently assembling the third flying prototype and preparing for its re-engining.

It is worth noting that the problems with engines for light aircraft have their roots in the Soviet past. The production of the An-2 and its ASH-62IR engine was transferred to Poland back in the 1960s, and the Czechoslovakian L-410, which was supposed to replace the Kukuruznik, was also produced abroad.

After the collapse of the USSR, Polish and Czech companies that produced this technique, came under the control of American corporations. As a result, Russia lost access to its own developments and depended on imports for a long time.

Ultimately, the creation of the VK-800 is an attempt to break this dependence. Although the documentation for the engine was acquired back in 1998, it was not suitable for installation on the Baikal.

In 2020, its deep modernization began: engineers reduced the weight and dimensions, increased the power. In some parameters, including fuel consumption, the VK-800 surpassed the American H80-100.

The engine is currently undergoing final testing, and its certification is expected by the end of the year, along with the new Russian propeller AV-901.

In the conditions of "geopolitical turbulence" many countries are looking for alternatives to Western aircraft, and Russian engines may be of interest to the markets of Asia, Africa and Latin America. If the project is successful, Russia will be able not only to restore its lost positions in light aviation, but also to offer the world competitive equipment.
