AgustaWestland and Eurocopter might be competitors in the helicopter market, but they seem to be decidedly good friends when it comes to defining rotorcraft for the future. In addition to partnering on the Erica tiltwing research project, they have joined forces on another European-funded project, dubbed Friendcopter.

The goal of the project is to create a helicopter that is quieter outside and inside. Friendcopter aims to reduce the acoustic footprint area by 30 to 50 percent and fuel burn by 6 percent in high-speed flight. In addition, the project aims to have cabin noise levels of less than 75 dBA. Cabin vibrations should be reduced to less than 0.05 g.
