Patent ID: 8573538

Claim:
A combination of the structural configuration of a rear fuselage and propeller engines of an aircraft comprising propellers formed by blades, with propeller engines being located at a rear part of the aircraft and the empennage of the aircraft being located behind the plane of the propellers, wherein the structural configuration of the rear fuselage comprises a double resistant shell comprising an outer skin and an inner skin, both skins being joined by means of radial elements configuring closed cells, wherein the cells are filled with a resistant material having a low density, such that the filling of resistant material has the effect of preventing local buckling of the cells of the structural configuration, thus stabilizing the multi-cell structural configuration of the rear fuselage, such that the obtained structural configuration increases torsional strength of the rear fuselage of the aircraft with respect to torsional loads coming from the empennage of the aircraft in the event of damage of the rear fuselage due to a detachment of one of the blades of the propeller engines.
