IVOPROP PITCH CHANGE DESIGN

AND HOW IT WORKS

The IVOPROP operates on a COMPLETELY UNIQUE adjustable pitch system that allows for substantially less hardware and rotating mass than any other ground pitch adjustable prop. The unique pitch adjustment design operates on the principle of twisting the blades through the chrome-moly alloy steel torsional rod cast inside the blade. The outer end of the torsional rod is firmly anchored inside the outer blade section. The round torsional rod is capable of rotating inside the blade, except for the outer end.

Below see a diagram of a Ivoprop Medium Model.

IVOPROP QUICK ADJUST SYSTEM

Adjust the pitch on the ground in a matter of seconds by turning the screw adjustor in the center of the prop. The super cams are installed on the end of the torsional rod. Each super cam fits into the groove in the screw adjustor. Turning the screw adjustor causes each cam to rotate and turn the torsional rod twisting the blade changing the prop pitch.

For Increase or decrease pitch on Quick Ground Adjustable Prop;

For Pusher configuration; Turn the screw adjuster CCW to ADD Pitch and decrease RPM, and Turning Screw CW will Decrease the Pitch and increase RPM, For Tractor will be the other way around.

IVOPROP IN-FLIGHT ADJUSTABLE SYSTEM

Pilot controls the pitch through the toggle switch mounted in the cockpit. Pressing the toggle switch one way sends electric current trough the graphite brushes to the slip rings and finally to the electric motor.
Depressing the toggle switch the other way reverses the polarity of current and the rotation of electric motor. The pitch changes operation is similar to the power windows in an automobile. As long as you hold the switch in one direction- the pitch changes in that direction and you observe the result on your RPM meter.
Torque from the electric motor is multiplied in planetary gear drive, which turns the lead screw.
Lead screw is supported by a thrust bearing and converts it’s rotary motion into axial movement of the spool.
The spool is linked to the supercams, which turn the torsional rods. Torsional rods transmit the movement from the center of the prop to the outside section of the blade. This causes the blade to twist therefore changing the pitch in the same manner as the ground adjustable pitch system.
Movement of the spool can be restricted each way by inserting washers on the lead screw. This limits maximum and minimum pitch and prevents engine over-revving.
Ground adjustable prop can be converted to the In-Flight Adjustable System by means of retrofit kit, In-Flight Adjustable Hub comes assembled with instructions on how to use it.
