A satellite dispenser door release mechanism is disclosed. In various embodiments, a satellite door dispenser as disclosed herein includes a wire or cable having a first end configured to be secured in a structure comprising or coupled to a dispenser body of a satellite dispenser and a second end configured to be secured in a structure comprising or coupled to a dispenser door of the satellite dispenser; and a pyrotechnic cutter configured to receive the wire or cable in a position to cut the wire or cable upon firing of the pyrotechnic cutter.

The invention discloses a spatial large-stroke compliant hinge with hybrid structure, which includes a rectangular planar unit for implementing an out-of-plane torsion function and a crossed-shaped planar unit for achieving an in-plane rotation function. The crossed-shaped planar unit is formed by two flexible straight beam thin sheets intersecting into a crossed-shaped structure with an angle, and the rectangular planar unit and the crossed-shaped planar unit are connected through an external connection or an embedded connection. The invention overcomes the problems that existing planar structure compliant hinge can only be equivalent to a large-stroke low pair with single degree of freedom, and existing LEMs compliant mechanism is equivalent to compliant hinge with multiple degrees of freedom and with smaller overall strokes. It has the advantages of simple structure, easy processing, easy analysis and calculation, equivalent large stroke space, and multiple degrees of freedom flexibility.

A multi-axis flexure device can include an interior flexure member and an exterior flexure member disposed about and coupled to the interior flexure member. The interior flexure member can have a first interior flexible blade connected to and integrally formed with a first interior end portion and an interior body portion. The interior flexure member can have a second interior flexible blade connected to and integrally formed with the interior body portion and a second interior end portion. The exterior flexure member can have a first exterior flexible blade connected to and integrally formed with a first exterior end portion and an exterior body portion. The exterior flexure member can have a second exterior flexible blade connected to and integrally formed with the exterior body portion and a second exterior end portion. The first interior end portion and the first exterior end portion can be coupled to one another to form a first flexure end portion, the second interior portion and the second exterior portion can be coupled to one another to form a second flexure end portion, and the interior body portion and the exterior body portion can be coupled to one another to form a flexure body portion, such that the first interior flexible blade and the first exterior flexible blade form a first cross-blade flexure operable to facilitate relative rotation between the first flexure end portion and the flexure body portion about a first axis, and the second interior flexible blade and the second exterior flexible blade form a second cross-blade flexure operable to facilitate relative rotation between the second flexure end portion and the flexure body portion about a second axis.

In various embodiments, a satellite door dispenser as disclosed herein includes a wire or cable having a first end configured to be secured in a structure comprising or coupled to a dispenser body of a satellite dispenser and a second end configured to be secured in a structure comprising or coupled to a dispenser door of the satellite dispenser; and a pyrotechnic cutter configured to receive the wire or cable in a position to cut the wire or cable upon firing of the pyrotechnic cutter.

A satellite dispenser and method of using same are disclosed. In various embodiments, a satellite dispenser as disclosed herein includes a dispenser body defining an interior cavity to accommodate a payload; and a plurality of externally adjustable restraints positioned within the interior cavity and configured to be extended further into the interior cavity by actuation of a manual interface external to the interior cavity.

A bearing liner includes a first fabric having a fiber sheet pre-impregnated with a binder. A second fabric is impregnated with the binder and has a bearing element contact surface with lubricating fibers and structural fibers supporting the bearing element contact surface. The fiber sheet and the binder incorporate electrically conductive fillers.

A flexural pivot can include a plurality of flexure support members, each flexure support member having a plurality of flexure openings and a plurality of wells each in fluid communication with a respective flexure opening. The flexural pivot can also include at least one flexure to rotatably couple the plurality of flexure support members to one another. The at least one flexure can have first and second flexible blades arranged in a cross configuration. The first and second flexible blades can be disposed in the flexure openings of the flexure support members, and coupling material deposited in the flexure openings can couple the first and second flexible blades to the flexure support members.

A flexural pivot can include a plurality of flexure support members, each flexure support member having a plurality of flexure openings defined at least partially by a cantilevered extension portion. The flexural pivot can also include at least one flexure to rotatably couple the plurality of flexure support members to one another. The at least one flexure can have first and second flexible blades arranged in a cross configuration. The first and second flexible blades can be disposed in the flexure openings of the flexure support members, and the cantilevered extension portions, at least in part, can couple the first and second flexible blades to the flexure support members.
