2.3
Construction
The 200G/210G Series propeller blades are constructed
from advanced thermoset composite materials. Each blade
is equipped with a nickel leading edge erosion shield to
protect the blade leading edge from rain and debris damage.
The 200G/210G Series hub is CNC machined from certified
aerospace aluminum alloy, which is then shot peened and
anodized. The hub blade sockets are equipped with ball
bearings to ensure smooth pitch change of the blades
throughout the life of the propeller system. This propeller
can be flown in rain and off unimproved airstrips.
2.4
Configuration
The 200G/210G uses a threaded “piston” whose position is
moved fore and aft when the adjustment screw is turned.
The piston is connected to the blade bases via pitch links.
The fore and aft movement of the piston rotates the blades
in the hub, changing their angle of attack (pitch).
Mechanical stops for high and low pitch limit the pitch
change travel; for the 200G minimum fine pitch of 10° and
maximum coarse pitch of 26°, for the 210G minimum fine
pitch of 9° and a maximum coarse pitch of 25°.
* Refer to the original propeller data sheet for initial factory
low pitch setting.
Do not change the pitch adjustment screw until the
propeller is installed on the airplane and the pitch scale
and indicator are applied to the blade ferrule and the
spinner dome (see Section 5 below).
2-2
Each Whirl Wind propeller system has a factory designated model
number and serial number, which will identify the hub and propeller
serial number. The propeller system blades will have individual
serial numbers etched on the ferrule of each blade near the root end.
All Serial numbers can be found on the owner’s data sheet.
