Innovative rotor blades (GRC1)

Challenge

The main rotor of a helicopter is both the main user of power (and hence fuel), and the main source of intrusive noise. Working directly to improve the efficiency and reduce the noise of the main rotor is a highly effective way of reducing fuel usage, CO2 and NOx emissions, and rotorcraft generated noise levels. 

Expected benefits

Current gain targets for rotor blades are -8% power in hover condition, -3% power in cruise, and -6dB in approach.
