The Russian VK-650V aircraft engine for the import-substituted Ansat helicopter surpasses its main competitors — the French Safran Arrius and the Canadian PW207. The comparison was made by the Aviation of Russia portal.
The domestic unit turned out to be better in four key parameters — emergency power mode, take-off power, dry weight, and specific fuel consumption.
| ВК-605В | Safran Arrius 2G1 | PW207 | |
| Take-off power, hp | 650 | 504 | 630 |
| Dry weight, kg | 115 | 110 | 114 |
| Specific fuel consumption in take-off mode, kg/hp h | 0,245 | 0,245 | 0,245 |
| Emergency power mode, min | 2,5 | 2 | 2 |
As a reminder, CIAM named after P.I. Baranov issued a conclusion on the readiness of the VK-650V for flight tests in the summer of 2025. At that time, seven prototypes were made for ground and flight tests at the facilities.
In the near future, ODK-Klimov (part of the United Engine Corporation, UEC) plans to complete certification tests of the engine as part of helicopters and begin mass production of the VK-650V.
Sergey Chemezov, head of the Rostec State Corporation, also noted that the range of the VK-605 also increased from 500 to 640 km, in this he is also better than his Canadian counterpart.
