DNW German-Dutch Wind Tunnels recently completed the aerodynamic testing of an advanced wind tunnel model of the EMBRAER KC-390, a new aircraft being developed by Brazilian manufacturer EMBRAER. The wind tunnel model was designed and manufactured by NLR. An official video clip depicting the aerodynamic tests was presented in São Paulo (Brazil) on 20 November, in the presence of the Prince of Orange of the Netherlands. The Prince of Orange and Princess Máxima are currently on an official visit to Brazil which will last from 19 to 23 November. The royal couple is being accompanied by a large delegation representing the Dutch private sector.

The new EMBRAER KC-390 wind tunnel model is an update of a previously tested older model. The latest wind tunnel tests included simulated in-flight refuelling of the aircraft, as well as payload parachute testing. In addition, a number of specially developed complex measurement techniques were applied to examine specific phenomena such as the velocity flow field.

This wind tunnel test is one in a series of tests being conducted for EMBRAER. The project is based on close collaboration between DNW and NLR, with each party contributing specific expertise to offer the client a ‘one-stop-shop’ approach. The highly sophisticated KC-390 wind tunnel model reflects the state of-the-art expertise necessary to perform complex wind tunnel tests. Particularly the simulated in flight refuelling operation using a hose and drogue system required creative and innovative solutions.
