초록 ▼

A one-piece composite material torque box for the thrust reverser assembly of a jet engine. The torque box is made up of three composite material subassemblies, a generally planar flange subassembly, a tubular torque tube subassembly, and a cap subassembly. The flange subassembly is configured to transmit tension loads from the cascades of the reverser assembly to the V-blade ring which engages the engine, and the fibers in the composite material are aligned with these load paths. The torque tube subassembly is mounted to the flange subassembly, and is configured to transmit torsion loads from the actuators of the reverser assembly to the upper and lower latch members of the engine assembly; the fibers of the composite material therein are aligned at 45° angles to the tube axis, so as to be in alignment with paths of the tension/compression components of the torsion loads. The cap subassembly extends over the torque tube subassembly and is bonded to the flange subassembly on either side thereof, so as to bond these three subassemblies together into a unitary structure.
