B-WWR72B

Whirlwind Blade

The WWR72B is a fully composite blade made by Whirlwind (USA). The configuration is right hand rotation.

 

Optimised planform shape and proprietary airfoils make these blades efficient and very quiet in operation.  The carbon fiber construction with X-Core™ ensures a safe, strong propeller with low inertia, suitable for small direct drive engines. The Nickel leading edge provides superior abrasion protection and the blade's high gloss natural carbon fiber finish will satisfy the most discriminating owner.

 

The WWR72B is specifically designed for geared engines operating at up to 2600 rpms.
