The MT-Propeller natural composite blades provide inside and outside noise reduction. They have no life limitation and are repairable in case of a FOD.
They also provide vibration damping characteristics and have bonded on stainless steel leading edges for erosion protection of the blades.
These propellers can be used on aircraft with piston engines and propeller turbines, as well as on airships, wind tunnels and hovercraft. They are also supplemental type certified on Part 25 aircraft.
