摘要

Element for control of the rotor head and control devices for rotary wing aircraft, in constructional variants known as heavy structure or light structure, and structured by two resistant tubes assembled by means of fittings in slight skewing with each other on the perpendicular, supporting and all the constituent elements and components of the airplane are located in them, and which characterizes, in the execution for light structure, by comprising a rectangular base piece on which are lodged two ball joints of different size joined by two lateral plates of conical shape, the larger axis influencing the axis of rotation and affecting it in the movement in all directions on the upper rotor connected to it by a crosshead, and having an axially displaceable cardan transmission, connecting at its lower end to a box of reducing gears of the corresponding motor, while the end opposite is geared to a casting pinion solidarity to the rotor head, both sets being actuated by a control lever supported by the structural central beam by means of a guide bushing, presenting mobility in all directions and being connected by two "T" arms to two command rods ascending and interconnected to the upper base pieces (Machine-translation by Google Translate, not legally binding)
