A method and apparatus for building a fuselage assembly for an aircraft. A number of fixtures may be drive across a floor to an assembly area to form an assembly fixture. The fuselage assembly may be built on the assembly fixture.

The present disclosure relates to systems and methods for producing an extruded protein product. In particular, a system for making an extruded protein product using a system that includes a die including channel having a transverse cross section that is a continuous loop along at least a portion of the length of the die is disclosed.

An attachment for an end effector. The attachment may include a clamp and a foot adhesively bonded to an edge of the clamp and having a set of interlocking features that form a mechanical interlock with the clamp.

An engine block assembly includes a head structure assembly, and a cylinder structure assembly. A plurality of fasteners interconnect the head structure assembly and the cylinder structure assembly. An outer shell encapsulates and supports both the head structure assembly and the cylinder structure assembly. The outer shell is a unitary polymer structure that is simultaneously over-molded onto the head structure assembly and the cylinder structure assembly. The head structure assembly and the cylinder structure assembly are constructed of components that are designed to carry the operational loads of the engine with minimal weight. The outer shell provides additional structural integrity, and provides fluid passages for lubrication and cooling, as well as support for other engine components.

An illustrative example embodiment of an elevator sheave assembly includes a plurality of polymer rings that are secured together. The plurality of polymer rings includes at least two polymer rings that each have an outer circumferential surface that defines a portion of a belt guiding surface adjacent a flange at a longitudinal end of the sheave assembly. The at least two polymer rings each include a bearing supported inside the ring.

Methods of joining components to form vehicle assemblies, such as engine assemblies, are provided. The methods include arranging a first component having a first channel defined therein in a mold, arranging a second component having a second channel defined therein in the mold, and aligning the first and second channel to define a pin-receiving channel. At least one polymeric composite pin is inserted into the pin-receiving channel thereby joining the first and second components, wherein an adhesive is disposed adjacent to at least a portion of the polymeric composite pin.

An insulating resin coating method for coating with an insulating resin a weld of a stator having a plurality of the welds formed by welding ends of coil wires together, the method including the steps of: sandwiching and covering the weld of the coil wires by a pair of resin-molding molds; and injecting the resin into the resin-molding molds by a resin injector.

A fibrous preform of a turbomachine component has a three-dimensional weave formed by a plurality of woven strands, wherein, in a shear plane of the component, all or part of the strands present in this plane have fibers forming an angle between 10? and 50? with their centerline.

Polymer compositions containing polyethylene particles having a multi-modal molecular weight distribution are disclosed. The polymer compositions are well suited to producing porous substrates through a sintering process. Formulations made according to the present disclosure can produce porous substrates having improved flexibility demonstrated by an increased flexural strength while still retaining excellent pressure drop characteristics.
