Longer Tail Rotor Blade Durability
In this TIP, Airbus Helicopters Deutschland proposes the sprayable erosion protection for the tail rotor blades.
The helicopter's tail rotor blades are adversely affected by erosion because of the high rotational speed in hover and the sum of rotational and forward speed during the flight. Especially the blade tip and the leading edge are not protected to that extent in sandy conditions. Therefore, the sprayable rotor blade erosion protection was introduced in order to increases the operating time and availability.
