A work platform configured to support one or more workers in proximity to a workpiece. The work platform includes sliders that are aligned along the length of the workpiece. The sliders are laterally movable towards and away from the workpiece. The sliders are individually movable with a position of each of the sliders relative to the workpiece being a function of the rotational position of the workpiece.

A method for erecting the structure of an aerostat in successive horizontal sections, starting from the top horizontal section, comprising an iteration of the following steps, starting from a current state of completion of the aerostat structure, lifting the current state of the structure, at first lifting points, by means of lifting means arranged in a current transverse position; placing a support device in line with second lifting points for lifting the current state of the structure; transferring the current state of the structure from the lifting means to the support device; moving the lifting means to another transverse position; completely assembling the horizontal section immediately below the current state of the structure on the structure.

A method for producing a frame component for a door frame structure of an aircraft. A connecting zone is generated on a first and a second assembly surface of a connecting component in each case by generating a surface texture on the assembly surfaces, wherein the connecting component is formed from a metal material. The assembly surfaces of the connecting component are placed against a door frame member and against an attachment member, wherein the door frame member and the attachment member are each formed from a fiber-reinforced thermoplastics material. Furthermore, the connecting component and the door frame member are welded, and the connecting component and the attachment member are welded. A frame component and a door frame structure are also described.

An air-conditioning duct structure of an aircraft includes an air-conditioning duct that is provided on each of a starboard side and a port side and guides conditioned air to a vicinity of a ceiling of a cabin in the aircraft. The air-conditioning duct includes a blowout portion and a blowout upstream portion. The blowout portion blows out the conditioned air to the cabin from an outboard side of the ceiling to an inboard side of the ceiling and toward a lower part than the ceiling, and the blowout upstream portion communicates with an upstream side of the blowout portion. In addition, the blowout portion or the blowout upstream portion is curved to cause a terminal end side of the blowout portion to be inclined downward with respect to a horizontal direction.

Methods of performing a plurality of operations within a region of a part utilizing an end effector of a robot and robots that perform the methods are disclosed herein. The methods include collecting a spatial representation of the part and aligning a predetermined raster scan pattern for movement of the end effector relative to the part with the spatial representation of the part. The methods also include defining a plurality of normality vectors for the part at a plurality of predetermined operation locations for operation of the end effector. The methods further include moving the end effector relative to the part and along the predetermined raster scan pattern. The methods also include orienting the end effector such that an operation device of the end effector faces toward each operation location along a corresponding normality vector and executing a corresponding operation of the plurality of operations with the operation device.
