Overview

Flash-R
    Longitudinal reinforced carbon structure
    Higher bending strength
    Titanium color finishing
    Advanced controls
The Flash propeller range with innovative design, specifically about its twisting axis and center of pressure. Its aerodynamic design allows a "constant speed" effect, limiting variations in engine speed between on ground and in flight.

These propellers allow for high efficiency throughout the flight envelope
    Improved takeoff and climb rate due to higher engine speed, then higher engine efficiency
    Many cruise extension
    A high user comfort
The blades and the hub of the Flash propeller range are manufactured according the DUC Hélices company technologies, from unidirectional layers of carbon fibers prepreg epoxy resin.

Their composite structures are defined to obtain the maximum stresses in torsion and bending. Therefore "constant speed" effect is not related to deformation of the blade but its geometry and specific profile.

Due to its specific geometric definition, excellent performance is obtained in both aerodynamic and acoustic, but also in consumption.

Shielding leading edge in Inconel
    The leading edge of the FLASH blades is equipped with a metallic shielding in Inconel®. This material is refractory stainless with a very high hardness of surface.
