The FLASHBLACK are the new generation innovative variable pitch propeller which have the best performances for all flight’s stages. These are a blend of carbon/titanium blades and carbon/aluminum hub which are manufactured in accordance with the DUC Propellers technologies.
The aerodynamic shape of blades uses the innovative design of the FLASH.
These propellers allow to have high efficiency throughout the flight envelope i.e.:
- High efficiency during takeoff and high climb rate
- High efficiency during cruise and maximum speed
- High user comfort
Equipped with grade 5 titanium hardware, this technology and manufacturing level and requirement degree have never been to this advancement. Their variable pitch carbon hub system allows a wide range of angle variation, while being secured by an innovative self-locking step system.
The setting of the pitch angle of the blades is "Constant Speed", in other words managed automatically by a hydraulic governor which regulates the propeller pitch according to its engine speed setting.
The pitch variation is done by the hydraulic power and the governor adjustment control is simply mechanical (pusher or lever). No electric current is consumed for this type of hydraulic variable pitch propeller.
