[Link mogu videti samo ulogovani korisnici]
Citat:On December 24, 2025, Ural Civil Aviation Plant (UZGA) in Yekaterinburg commenced joint flight tests of the VK-800 engine and AV-901 propeller integrated into the LMS-901 “Baikal” aircraft.
Citat:The AV-901 single-action propeller uses a feather-reversible design with a single hydraulic control channel. Its nominal rotation speed reaches 1,900 rpm, and the calculated maximum thrust of an isolated propeller is at least 15 kN. The propeller is entirely domestically produced, and its materials and control components meet industry certification standards.

In April 2025, the Russian Ministry of Industry and Trade (Minpromtorg) awarded UZGA a contract for experimental design work to develop the LMS-901 “Baikal” with a domestic powerplant. The contract’s maximum value is 10.4 billion rubles, with completion expected by December 17, 2027.

The program includes manufacturing new and upgrading existing VK-800SM engines, AV-901 propellers, and LMS-901 aircraft, conducting preliminary and static tests, and preparing certification documentation for type approval and major modification endorsements (OGI). The certification program covers engine and propeller performance, operational mode evaluation, emergency system validation, and aircraft integration.
