United Engine Corporation (ODK, part of Rostec) has approved the layout of the new VK-1600S turboprop engine for small passenger aircraft, including the An-2 and An-3. This is the first power plant of this class in Russia, with a power output of 1450 hp.
ODK clarified that the engine was built based on the VK-1600V helicopter engine, with a unification degree of 60–65%.
During development, the free turbine was modified, and new gearbox and accessory drive units were created. The use of a modern FADEC-type electronic control system will ensure stable engine operation in the altitude range from 300 to 4500 m at 100% relative humidity and temperatures from -50 to +55 degrees Celsius.
The VK-1600S is designed for small passenger aircraft, such as the TVS-2DTS. It can also be used for An-2 and An-3 aircraft – there are still many such machines in Russia, so there is a need for new engines.
ODK added that the VK-1600S will be used on aircraft as part of a single-engine power plant in conjunction with the AV-17 propeller.
Recall that the An-3 was conceived as a deep modernization of the legendary "Kukuruznik" An-2 by replacing the piston engine with a TVD-20 turboprop engine. But the Omsk TVD-20 engine turned out to be capricious, expensive to maintain, and had a short overhaul life. Now the project has a chance for a second life.
