<p>The mechanism and procedure for adjusting the pouring angle to the helicopter rotor blade of compact type, is located in the rotor hub (4). The modification of pouring angle is implemented by swinging the blade around the outlet shaft axle (44), which is provided by tilting and axial displacement of the rotating disk (5). The tilting of the rotating disk (5) is provided in two levels which are at a right angle against each other with a crossing located basically parallel to the driving shaft (3), while in the first of the two levels the translation of the internal control element (1) along the driving shaft (3) axle is achieved. In the other level this is achieved by rotating the internal control element (1) around the driving shaft (3) axle, which is at the same time also the proper axle of the internal and external control element (2). The raising of the rotating disk (5) above the reference level is provided by a translation of the external control pipe-like element (2). The control elements actually control the stationary disk (9), which rotates or lets the rotating disk (5) slide along it with the help of transmission mechanisms.</p> |
