Abstract: Embodiments for commercial freighter configuration for aircraft with composite wings. One embodiment is cargo floor structure for a wing center section of an aircraft. The cargo floor structure includes over wing floor beams extending longitudinally between a rear spar and a front spar of the aircraft. The over wing floor beams are coupled with an upper skin panel of a composite wing. The cargo floor structure also includes intercostals extending spanwise across the over wing floor beams. The intercostals suspended over the upper skin panel of the composite wing. The cargo floor structure also includes a truss box structure disposed between a middle pair of the over wing floor beams and configured to shear a spanwise load from the intercostals into the upper skin panel of the composite wing.

Abstract: A side of body carbon fiber reinforced polymer (CFRP) composite rib assembly that is formed by connecting an aft CFRP rib web, a middle CFRP rib web, and a forward CFRP rib web together. The side of body CFRP rib assembly includes a plurality of stiffeners connected to the aft CFRP rib web, the middle CFRP rib web, or the forward CFRP rib web. A first stiffener connects the aft CFRP rib web with the middle CFRP rib web and a second stiffener connected the forward CFRP rib web to the middle CFRP rib web. The stiffeners may be connected via fasteners or may be co-bonded or co-cured with the side of body CFRP rib web. The stiffeners connected to the side of body CFRP rib assembly may include more than one shape and may be aluminum, a thermoset, and/or a thermoplastic.

Abstract: A system is disclosed for displaying storage capacity status information for one or more passenger storage bins in an aircraft. Load sensors are coupled to each passenger storage bin and provide an output signal proportional to a weight of items within the bin. Range sensors are also coupled to each passenger storage bin and provide an output signal proportional to an amount of empty space available within the bin. A processor is coupled to the associated load sensors and range sensors and calculates, based upon the output signals from the load sensors and the range sensors, whether the associated storage bin is filled to capacity. The processor is also coupled to a display device to provide a status signal. The display device provides a visual indication based upon such status signal whether or not the associated storage bin is filled to capacity.
