Another fascinating day, with an unveiling and a chance to talke to Airbus engineers about the Blue edge technology.

Kopter booth (formerly Marenco Swiss Helicopter) before the unveiling

As the helicopter is unveiled it appears that the pilots are being unveiled with it!

The latest prototype of the SH-09 Kopter.

Blue edge technology – this is the highly developed H160 blade that reduces noise and makes the helicopter more effecient by allowing the same lift for a reduction in power and hence fuel burn
