The testing of counter-rotating propfan for long-haul aircraft engines was completed by TsAGI

The specialists of TsAGI in the area of aerodynamics, acoustics and durability have completed testing of a counter-rotating (coaxial) propfan model for advanced long-haul aircraft engines, press-service of TsAGI reports.

“The propfan design was developed by Central Institute for Aviation Motor Development named after P. I. Baranov (CIAM). The test model was manufactured by TsAGI. It was tested in wind tunnels T-104 and T-107. The work was carried out in accordance with the order of Russian Ministry of Industry and Trade. The tests were aimed at investigating the aerodynamic and acoustic characteristics of the propfan in takeoff and landing mode, and also the cruising flight mode at Mach numbers varying from 0 to 0.8. The operating modes of the propfan were simulated at different flight and blade rotation speeds and by changing the blade angles”, - TsAGI explained.

New developments and studies in the area of 10–20 thousand kW aircraft engines with counter-rotating propfans will help develop the long-haul aircraft with significant fuel savings and low noise footprint.
