Description

Pattern-less molding technology and 100% CNC machining ensures industry leading geometric accuracy of the blade area section, hub and root. The resulting SPP sections, and elimination of any imperfections in the fairness of the blades and boss lead to significantly quieter and smoother delivery of thrust. which allows LDU series propellers to achieve high speeds in excess of 50 knots with little to no signs of cavitation erosion on the blades. CAD/CAM computer developed Patterns fully CNC machined Smoothness through geometric accuracy of manufacturing. Rapid acceleration across full RPM range Quality highly successful anti-singing edge detail, Minimum manufacturing accuracy of ISO 484/2 Class S, ISO 1940/1 G2.5 (gas turbine) high accuracy dynamic balancing, pitch Distribution: - custom Blade Section Type: - SPP Skew: - 0 degree Blade Rake: - 6 degree
