The FLASH-2 propeller range has a new innovative design, specific about its twisting axis and center of pressure.
Pusher propeller, new design optimized for STOL performance Ideal for short take-off and mountain flying.
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 i.e.:
- Improved takeoff and climb rate due to higher engine speed, then higher engine efficiency
- Many cruise extension
- A 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.
