A pylon (14) for supporting a turbo-fan jet enginef a cabin in the body of an airplane, a transparent board is mounted on the outer portion for sealines to the forward and aft parts of the engine coreounted in the inner side of the transparent board e wing (10) while resisting static and dynamic forces applied by the engine and the nacelle of the e cabin side of the dust cover for blocking outer in bifurcation portion(16), having an upper end (23) and a lower end. The upper end (23) is positione the surface of the transparent resin board facing the shade. The acrylic resin used as the material of the transparent resin board expands by absorbing the water in the air, but by the operation of t lugs (38) to the aft part of the engine core (22), and a forward section that is attached to the foerfere with the locus L1 of the up and down moveme beams (18, 20) extend forward from opposite sides of the forward section of the lower portion of the pylon bifurcation portion (16) and attach to different locations on the forward part of the engine core (22). The cowl beams (18, 20) resist the majority portion of torque forces applied by the engine (12) to the pylon (14). |
