Semi Symmetric Blade size 325 mm

For these blades we are using an asymmetrical air foil. These blades are producing lift at an angle of attack (pitch) of 0 degree already. They are specially developed for pilots who like to fly helicopters with a fuselage and who aim for extended flight times.

Energy is saved due to the asymmetrical air foil, since it produces lift at an angle of attack of 0 degree already. The low angle of attack produces less drag compared to symmetrical blades and less energy is needed to rotate the blade. Furthermore the chord of the blades has been increased, decreasing the aspect ratio, and reduces the circular wing loading by not changing the wing span. Furthermore the center of gravity of the blade has been shifted more to the outside, forcing the angle of the longitudinal axis of the blade the rotation axis to decrease. All these factors are allowing using less rpm for fl ying operations. Less energy is used; less wear and tear on all moveable parts and longer lifetime of the helicopter are other side effects.
