Abstract
The present invention relates to a bellcrank () for a flight-attitude-changing linkage (A,A) of the variable gain type. The linkage (A,A) connects a manual flight control device of a rotary wing aircraft (), e.g. a hybrid helicopter, to at least one airfoil of said aircraft () suitable for causing a change in flight attitude. Said bellcrank () includes first and second sliders (). Said first slider () is connected to a movable portion () of a setpoint flight-attitude-changing linkage () that delivers a setpoint, with movements of said linkage causing the gain of said variable-gain linkage (A,A) to be adjusted, which gain is proportional to the position of said movable portion ().
