FIELD: aviation.SUBSTANCE: propeller blade (1) contains an outer shell (20) extending along a span and a chord and, at least, one control panel (4) extending, in essence, along the span towards the named outer shell (20), at least, one blade chamber (7) inside the outer shell (20). The load transmission medium located in the chamber (7) contains the housing (13) of package type, respectively, with one switch (8, 9), one drive (10, 11) of the control panel and the longitudinal beam (15). The housing (13) contains, at least, one top jumper (14) and, at least, one bottom jumper (14) oriented, in essence, along the named chord between the named longitudinal beam (15) from one side, and the switch support (8, 9) from the other side. Each of the named bottom and top jumpers (14) is symmetrically levelled along a chord with reference to, at least, two swinging support (35, 36). The named top and bottom jumpers (14) rigid along a chord and flexible along a span. The switch (8, 9) can be implemented in the form of piezoswitch.EFFECT: improvement of efficiency of load transfer to a control panel.8 cl, 4 dwg |
