Blue Edge rotor blade (Eurocopter)

In summary, Eurocopter has unveiled their new Blue Edge rotor blade which has been tested on their EC155 helicopter and shown to reduce noise by 3 to 4 decibels. This is a significant step towards reducing helicopter noise. The video of the new blade in action is pretty impressive. However, some may argue that the iconic sound of a Huey helicopter cannot be beaten, despite its loudness.

Pretty cool.

You can't beat the sound of a Huey though!

Huey's are atrocious. They fly over campus, every day - all day. Whap Whap Whap...you can hear them having blade slap from five miles out - literally. It gets old...
 

1. What is a Blue Edge rotor blade?

A Blue Edge rotor blade is a type of rotor blade used on Eurocopter helicopters. It is designed with a swept-back and tapered shape, and has a distinctive blue-colored edge. The blade is made from composite materials and is designed to improve aerodynamic performance and reduce noise during flight.

2. How does the Blue Edge rotor blade improve aerodynamic performance?

The Blue Edge rotor blade's unique shape and composite material construction allows for improved lift and reduced drag, resulting in better overall aerodynamic performance. This leads to increased fuel efficiency and better handling for the helicopter.

3. What is the purpose of the blue-colored edge on the Blue Edge rotor blade?

The blue-colored edge of the Blue Edge rotor blade is not just for aesthetic purposes. It is actually a special coating made of a durable, erosion-resistant material that helps to protect the blade and maintain its aerodynamic shape over time. The blue color also helps with visibility and makes it easier for pilots to see the blade during flight.

4. Are Blue Edge rotor blades compatible with all Eurocopter models?

Currently, Blue Edge rotor blades are only compatible with certain models of Eurocopter helicopters. These include the H135, H145, H175, and H225. However, Eurocopter continues to develop and expand the use of Blue Edge rotor blades for other models as well.

5. How does the Blue Edge rotor blade reduce noise during flight?

The Blue Edge rotor blade's unique shape and composite material construction also help to reduce noise during flight. The blade's design reduces the amount of noise created by air passing over it, making for a quieter and more comfortable flight experience for both the pilot and passengers.
