The light aircraft LMS-901 "Baikal", which should replace the Soviet An-2, is undergoing ground frequency tests. They allow to identify the resonant frequencies of the structure and eliminate dangerous vibrations in flight, the Ministry of Industry and Trade reported.
The work is carried out by specialists from the Ural Civil Aviation Plant (UZGA) and SibNIA under the supervision of TsAGI and the Aviation Register. At this stage, engineers check the dynamic characteristics of the airframe and control system.
Successful completion of the tests will pave the way for the next stage — flight certification. The Ministry of Industry and Trade expects to complete the entire cycle of tests by the end of 2026.
As a reminder, the "Baikal" is designed for 9 passengers, develops up to 300 km/h and is capable of flying up to 3000 km.
The project should close the shortage of light aviation on local airlines, where outdated "corncobs" are still used. However, the main issue remains its cost, which may be unaffordable for regional airlines.
