A FLAPPING ABUTMENT MECHANISM FOR A LIFT ASSEMBLY, A ROTORCRAFT ROTOR INCLUDING THE ABUTMENT MECHANISM, AND A ROTORCRAFT

摘要

The present invention relates to a stop mechanism (20) of a lift assembly (11) of an aircraft (1). The stop mechanism (20) comprises a single rigid rod (21) having a variable deflection, said connecting rod (21) comprising a rod (30) and a body (40), said rod (30) being movable in translation relative to said body (40) along the longitudinal direction (D1) along said travel, said stop mechanism (20) having a displacement member (50) for adjusting an amplitude (70) of said travel as a function of at least one predetermined parameter said connecting rod (21) comprising two end pieces (26, 27) adapted to be articulated respectively to a said lift assembly (11) and to a said drive system (15).
