SUSPENSION STRUCTURE WITH VARIABLE GEOMETRY OF A TURBOPROP ENGINE ON A STRUCTURAL ELEMENT OF AN AIRCRAFT

摘要

The invention concerns a suspension structure (100) with variable geometry of a turboprop engine (4) on a structural element of an aircraft, comprising a rear cradle (102) intended to be attached to a structural element of an aircraft and a front cradle (104) intended to support a front portion of the turboprop engine, the front cradle being linked to the rear cradle by a pivot link (116) capable of allowing the front cradle to tilt vertically relative to the rear cradle, and by a return spring (120) capable of preventing the front cradle from tilting when the thrust of the turboprop engine is below a predefined threshold.
