The specialists of TsAGI’s powerplant department have completed the first stage of testing of PD-14 engine nacelle. The nacelle was tested at speeds of М=0.82 and lower, press-service of TsAGi reports.

The studies were aimed at defining the aerodynamic performance of the PD-14 engine nacelle (this advanced engine is being developed by Aviadvigatel (Perm, Russia)). It is planned that PD-14 engines will power MS-21 aircraft. The nacelle was tested in TsAGI’s T-106 trans-sonic wind tunnel.

The special model of the nacelle with different variants of outlines was designed by TsAGI and manufactured by Aviadvigatel. The model’s preliminary testing was completed earlier using high-speed rig SVS-2, the press-service noted.

«The first experimental studies provided us with some important results. The claimed performance has been confirmed. On the other hand we have obtained new information that requires analysis and repeated tests in a wider range of parameters. The results of such tests allow us to optimize the design of a powerplant», – head of TsAGI’s powerplant department, Vladimir Akinfiev, said.

The next stage of PD-14 engine nacelle testing will be started in spring 2014. The model will be tested in TsAGI’s T-106 trans-sonic wind tunnel, the press-service noted.
