Frigate Ecojet Launches Second Stage of Aerodynamic Testing in Germany
11 July 2014

Frigate Ecojet and ThyssenKrupp System Engineering have signed an agreement for conducting aerodynamic tests in the European Transonic Windtunnel (ETW) in Germany. The main objective for testing is to identify aerodynamic parameters that most closely resemble actual flight conditions.

“The first stage of testing stage at the Central Institute of Aerohydrodynamics in Moscow in 2013 confirmed earlier stated specifications,” said Frigate Ecojet Chief Designer Vladimir Chernousov. “We have enhanced the aerodynamic design in order to improve these specifications. Throughout the entire project we have sought to use the most advanced technologies available in today’s flight engineering industry. This is why we have decided to conduct the second stage of testing in the low temperature wind tunnel in Germany.”

Tests will be conducted at the European Transonic Windtunnel in Cologne, equipped with the most modern aeronautical wind-tunnel infrastructure in the world. Testing at the ETW includes the use of an advanced closed aerodynamic circuit contained within an internally insulated stainless steel pressure shell. A compressor with drive power of up to 50 MW circulates nitrogen gas around the circuit to simulate temperatures of high altitude flight approaching -50C.

The wind tunnel aircraft model will be produced by Deharde Maschinenbau GmbH, specializing in the design and manufacture of both wind tunnel models and full scale flight articles.

ThyssenKrupp System Engineering, an engineering subsidiary of the German ThyssenKrupp group, will act as integrator of the aerodynamic testing programme.   

The testing programme is expected to be completed in January 2015.
