The propfan and its components together with D-27 engine and propfan control system provide the reliable operation of the powerplant over a period of 300 hours (specified by the state testing program). In future the engine’s overhaul period will be increased to 20 thousand hours.

In addition, the representative of the MoD noted that the propfan is ready for serial production and operation.
