STRESS INTERFACE, IN PARTICULAR, AIRCRAFT STRUCTURE STRESS INTERFACE AND ITS APPLICATION Russian patent published in 2014 - IPC B64C1/14 

FIELD: aircraft engineering.

SUBSTANCE: proposed interface comprises grate structure made of plastic reinforced by fiber and load transfer flange. Grate structure comprises edge part and beam. Edge part is adapted to said beam. Flange is adapted to edge part and mounted thereat. Flange has angular top transfer surface and angular bottom transfer surface to transfer crosswise forces and bending moments originating due to transfer of crosswise forces at load transfer flange and/or to transfer circular and/or lengthwise forces and torsion/bending moments caused by transfer of circular and/or lengthwise forces at stress transfer flange. Edge part is furnished with one bottom and/or top transfer surface. Bottom or top transfer surface of angular edge part is parallel with angular top transfer surface or angular bottom transfer surface of the flange. Said surfaces are arranged at 90 degrees to each other. Grate structure is oriented relative to edge part at 90 degrees.

EFFECT: smooth transfer of concentrated stress to bearing structure.
