SAAB Aerospace AB was exhibiting its "stealth" technology for the first time at a wind event at EWEC 2006. The low signature materials are designed to make objects invisible to aviation radar systems and are being transferred from the military aircraft sector to the wind industry. "The one millimetre thick layer can be applied on standard blades without the need for modifications at a cost of around EUR 15,000 per megawatt," explained Saab's Magnus Landberg. The technology is currently being tested on aircraft, he said. But Saab, which is 20% owned by Britain's BAE Systems, hopes to get approval for a EUR 1 million trial on a wind project. "Our plan is to test the wind turbine without any coatings as a control and then with the absorbent materials," said Landberg.
