The fully assembled demonstrator of the domestic helicopter engine has already been installed on a special test bench. Testing of the power plant will begin in the near future.
The first flight tests of the VK-650V are scheduled for 2022. The engine should be certified in 2023, and mass production is expected to begin in 2024.
