A tail for a projectile includes a body having a longitudinal axis. A steering assembly is secured to the body. The steering assembly includes a flap movable from a first position in which the flap does not extend radially beyond the body to a second position in which the flap extends radially beyond the body and at an angle relative to the longitudinal axis, and a flap release mechanism. A projectile including a tail according to the present disclosure is also provided.

Deployable flap for high-G maneuvers

A reservoir provided in a hard-point fixture is pre-loaded with a curable adhesive, where the reservoir is protected from the curing radiation. The fixture is placed on a target surface and the adhesive is extruded from the reservoir into a space between the fixture and the target surface. An irradiating device to cure the adhesive is provided in the fixture and activated to couple the fixture to the surface. Once the curing process is complete, the fixture is released from the placement system leaving the fixture affixed to the target surface.

Hard-point fixture for attaching to a target surface

A hard-point fixture placement system places a fixture that is pre-loaded with a curable adhesive by mechanically extruding the adhesive between the fixture and a target surface to which the fixture is to be attached. The placement system includes an irradiating device to cure the adhesive. The hard-point fixture stores the adhesive in a reservoir that is protected from the curing radiation. Once the curing process is complete, the fixture is released from the placement system leaving the fixture affixed to the target surface.

Hard-point fixture and system for attaching the fixture to a target surface

A mold for casting a micro-scale structure includes an upper surface including a first cavity having a first depth. A negative pattern for an array of micro-scale structures is defined in a surface of the first cavity. The mold includes at least one second cavity having a second depth defined in the cavity outside of the negative pattern for the array of micro-scale structures. The at least one second cavity defines a negative pattern for a standoff of the micro-scale structure. A fabric retaining frame is disposed in the first cavity.

Polymer microwedges and methods of manufacturing same

A surface affixable device incorporating mechanically actuated dry adhesive includes a body and a plurality of tiles affixed to the body. Each of the plurality of tiles includes an array of dry adhesive material elements disposed on front faces thereof. A first of the plurality of tiles is movably affixed to the body. An actuator is constructed and arranged to displace the first of the plurality of tiles in a first direction relative to a second of the plurality of tiles. A biasing element applies a bias to the first of the plurality of tiles in a second direction upon displacement of the first of the plurality of tiles in the first direction.

Surface affix-able device incorporating mechanically actuated dry adhesive

A hybrid adhesion system includes an adhesion head including at least one suction cup and a handle and a vacuum generator mechanically coupled to the adhesion head. The vacuum generator includes at least one pneumatic cylinder having an internal volume in fluid communication with the at least one suction cup and a piston having a piston rod mechanically coupled to a manual actuator.

Hybrid adhesion system and method

The systems and methods described herein related generally to a device that enables the directional control of flow through an anatomical tract of the body. More particularly, the device described herein includes a valve from a plurality of projections. In some implementations, the projections are configured as flaps, posts, or any combination thereof. In some implementations, the device is implanted into a patient's esophagus to prevent gastroesophageal reflux disease. The plurality of projections allow flow into a patient's stomach while substantially preventing a backflow of undesired fluids from the patient's stomach to the patient's esophagus.
