Embodiments of systems, devices, and methods are described that relate to module structures for use in forming a cabin interior of an aircraft. Many embodiments relate to a support structure including a lattice configurable to provide a standardizable frame for connection to the interior of the aircraft and to provide a space within the frame in which module fixtures can be positioned and secured to the frame. Embodiments of the support structure can include a floor with a number of structures and devices that can be used to provide support for the module and secure the module to the floor of the aircraft fuselage. Embodiments of transport systems for the modules are also described and such can be integrated with the floor of the module such that the modules transport mechanism, or a significant portion thereof, is contained within the module itself.

An emergency exit system comprising a first primary structure frame, a second primary structure frame extending substantially parallel to the first primary structure frame, a door opening arranged between the first primary structure frame and the second primary structure frame, and a door shiftable substantially parallel to the first primary structure frame and the second primary structure frame between a closed position and an open position. In the closed position, the door closes the door opening. In the open position, the door opens up the door opening. At least one of the primary structure frames comprises a primary structure guide element for guiding the door when the door is shifted between the closed position and the open position.

In one embodiment, an unmanned aircraft comprises a housing, an inflatable fuselage, three motors, and three propellers. The housing may comprise an enclosure configured to house one or more electrical components. The inflatable fuselage may comprise a first, a second and a third spindle each extending from the housing. The first motor may be coupled to a first propeller and mounted to the first spindle. The second motor may be coupled to a second propeller and mounted to the second spindle. The third motor may be coupled to a third propeller and mounted to the third spindle.

A pressurized, fluid-filled channel network embedded in an elastic structure, asymmetrically to the neutral plane, is used to create a deformation field within the structure by the pressurization of the embedded fluidic network, which can be applied in accordance with external forces acting on the structure. The deformation of the structure resulting from the liquid pressure and geometry of the network is related to a continuous deformation-field function. This enables the design of networks creating steady arbitrary deformation fields as well as to eliminate deformation created by external time varying forces, thus increasing the effective rigidity of the beam. By including the effects of the deformation created by the channel network on the beam inertia, the response of the beam to oscillating forces can be modified, enabling the design of channel networks which create pre-defined oscillating deformation patterns in response to external oscillating forces.

Methods are provided by which a treatment fluid (e.g., a liquid corrosion inhibitor) may be applied onto the interior surfaces of an aircraft fuselage. The methods include (a) deploying an automated guided vehicle (AGV) comprising a carriage assembly and a robotic spray system carried by the carriage assembly within the interior of the fuselage, (b) closing the cabin door opening of the fuselage with the AGV positioned therewithin, and (c) operating the AGV so as to move within the fuselage along a longitudinal axis thereof to spray the treatment fluid onto the surfaces thereof.
