Cyclic pitch actuation system for counter-rotating propellers

摘要

A counter-rotating propeller system (14) comprises a cyclic pitch system (60) connected to a first plurality of propeller blades (18) and a variable pitch system (100) connected to a second plurality of propeller blades (20). The first plurality of propeller blades (18) and the second plurality of propeller blades (20) are configured to rotate about a common axis (A).
