A joint realizing higher rigidity without increasing the wall thickness provided with a base part 12, a pair of side parts 14, 14 extending from the two end parts of the base part 12 in the first direction D1 to the same side in the second direction D2 vertical to the first direction D1, the pair of side parts 14, 14 being formed with fastening holes 14H at the center in a third direction D3 vertical to both the first direction D1 and second direction D2, and a closed part 16 formed between the pair of side parts 14, 14 as an extended region of the base part 12 and pair of side parts 14, 14 at least at one end in the third direction D3.

A fracture-resistant double shear joint including a clevis having a first end defining a first bore and a second end defining a second bore, and a reaction load member defining a third bore, wherein the first bore, the second bore, and the third bore are colinear. The fracture-resistant double shear joint can further include a first spacer positioned within the first bore, a second spacer positioned within the second bore, and a shear pin positioned within each of the first bore, the second bore, and the third bore. The shear pin may include an outer cylinder, an inner shear bolt threaded on both ends, and nuts at either end that engage the threads. The nuts may be tightened to place the outer cylinder in compression. The spacers in the first and second bore may include a low friction liner that interfaces with the outer cylinder of the shear pin. The ends of the spacers may be set back from the ends of the first and second bores (that are next to the third bore).

A hinge assembly such as a lead-lag hinge can include a hinge pin assembly. The hinge pin assembly can include an outer cylinder, a shear pin that extends through the outer cylinder and having a first threaded end and a second threaded end, a first nut threaded on the first threaded end and a second nut threaded on the second end. An opposing force between the first nut and the second nut applies a compressive stress to the outer cylinder that may increase a resistance of the hinge pin assembly to wear and damage. In the case of complete failure of the outer cylinder, the shear pin can maintain structural integrity of the hinge pin assembly and of the hinge assembly.

A filament wound composite fibre reinforced polymer shaft comprising helical wound fibres, the shaft having at least one hole perpendicular to an axis of the shaft; wherein fibre paths of the helical wound fibres divert around the hole. The hole can be used as an attachment point to connect the shaft to other parts, e.g. by means of a pin passed directly through the hole. The amount of metal used in this type of connection can be significantly reduced compared to using metal end fittings, thus greatly reducing cost and weight of the whole system. Fibres are diverted around the hole rather than the hole being cut through the fibres which would reduce the strength of the shaft as a whole. By diverting the fibres around the hole, the fibres retain their load bearing properties and the strength of the shaft is maintained even in the presence of the hole.

A torque link assembly for a landing gear includes a lower torque link and an upper torque link that releasably engage first and second quick release pin assemblies. The pin assemblies each include a housing attached to one of the torque links, and a locking pin member extending through the housing. The locking pin member includes a rod portion and a pin portion, and is slidable between an engaged position and a disengaged position for hingedly connecting/disconnecting the torque links. One of the housing and the locking pin member includes a channel having a longitudinal portion and a circumferential portion, and the other has a guide pin that engages the channel. The guide pin is in the longitudinal portion of the channel when moving between the engaged and disengaged positions, and is retained in the disengaged position when the guide pin is in the circumferential portion of the channel.

A rotating shaft mechanism includes a first connecting portion, a second connecting portion, a central shaft rotatably connected to the first connecting portion and the second connecting portion, and an adjusting unit disposed on the central shaft. The adjusting unit includes an adjusting ring disposed around the central shaft, a first washer disposed around the central shaft and configured to generate a force to the first connecting portion or the second connecting portion. A position of the adjusting ring with respect to the central shaft is axially adjustable for adjusting the force so that the first connecting portion or the second connecting portion is rotatable or fixed relative to the central shaft.

A strut end piece for a strut for connecting with a fin of a sleeve for a solar mirror frame support. A strut for receiving a strut end piece for a solar mirror frame support. A sleeve for connecting with a chord and a strut end piece for a solar mirror frame support having a main portion having an opening for receiving the chord. A method for connecting a sleeve to a chord and a strut end piece for a solar mirror frame support.

A clevis, particularly for a turbomachine includes a body that is attachable to a casing and at least one aperture for fitting a hinge pin. The body is formed in one piece and includes, about the at least one aperture, a honeycomb-type annular portion. The annular portion acts as a vibration filter and has a compressive and/or flexural strain capacity greater than that of the rest of the body.

A hinge assembly such as a lead-lag hinge can include a hinge pin assembly. The hinge pin assembly can include an outer cylinder, a shear pin that extends through the outer cylinder and having a first threaded end and a second threaded end, a first nut threaded on the first threaded end and a second nut threaded on the second end. An opposing force between the first nut and the second nut applies a compressive stress to the outer cylinder that may increase a resistance of the hinge pin assembly to wear and damage. In the case of complete failure of the outer cylinder, the shear pin can maintain structural integrity of the hinge pin assembly and of the hinge assembly.
