An assembly for deployment and retraction of a panel for outer space environment usage, includes a member secured to the panel with the member having an axis of rotation. Mass component connected to the panel, with panel wrapped about member with mass component positioned a first radial distance from the axis of rotation. Mass component has a mass per unit area greater than a mass per unit area of the panel adjacent to the mass component. With a rate of rotation of the mass component and member being same, the mass component rotates about the axis of rotation at a second radial distance from the axis of rotation, wherein the second radial distance is greater in dimension than the first radial distance. With a rate of rotation of the mass component and the member changed to be different, radial distance of the mass component to the axis of rotation decreases.

Re-useable, deployable, sun-shade and solar sail mechanism

Aerodynamic microstructures having sub-microstructure are disclosed herein. One disclosed example apparatus includes an aerodynamic microstructure on an external surface of a vehicle, and sub-microstructures superimposed on the aerodynamic microstructure, where the sub-microstructures are spaced to reduce reflections.

Aerodynamic microstructures having sub-microstructures

A light configured to be coupled to a surface, where the light includes a light source configured to emit light in three dimensions and a lens configured to direct a majority of the light emitted by the light source outwardly from the light source in directions along the surface. The light may be an anti collision light for an aircraft.

Very low profile anti collision light

Aerodynamic microstructures having sub-microstructure are disclosed herein. One disclosed example apparatus includes an aerodynamic microstructure defining an external surface of a vehicle, and a pattern of sub-microstructures superimposed on the microstructure to convey a representation of an image.

Optical effects for aerodynamic microstructures

A method for fabrication of a non-pneumatic tire and wheel assembly incorporates a tire tread and a conventional vehicle wheel with an elastomer tire body element formed by introducing elastomer into mold elements with a center plug and releasably carried chamber forms to provide integral wall elements extending radially inward from the tire body element for sealing engagement with the wheel. The tire body element includes multiple concentric layers with alternating spokes formed with strut and aperture dimensions in the mold elements and mating rubber cast blocks adapted for the desired spoke design. After curing, the tire assembly is mounted on the conventional wheel with conventional mounting tools to deform the integral side walls and a pneumatic chamber formed by the side walls is inflated.

Method for fabrication of a non-pneumatic survivable tire and wheel assembly

A non-pneumatic tire and wheel assembly is fabricated by forming inner and outer mold elements having apertures to receive casting blocks. A tread having an inner wall is prepared for casting and fill apertures are machined in a rim of a metal wheel. The tread, the outer mold element, the wheel, the inner mold element and the rubber casting blocks are assembled and an elastomer is introduced into the mold assembly through fill tubes inserted in the fill apertures of the wheel. The elastomer is allowed to cure at room temperature to form a tire body element and the rubber casting blocks and inner and outer mold elements are disassembled. A post-cure of the disassembled tire body element is accomplished at a high temperature.

Systems and methods described herein provide for the protection of personnel within vehicles and structures from rocket-propelled grenades and other incoming threats. According to one aspect of the disclosure provided herein, a countermeasure system includes an interceptor vehicle configured to stow and launch an expandable countermeasure. The countermeasure may have a flexible body with attached deployment mechanisms that expand the flexible body into the path of an incoming threat to capture the threat.

Projectile-deployed countermeasure system

Systems and methods described herein provide for the protection of personnel within vehicles and structures from handheld grenades and other threats. According to one aspect of the disclosure provided herein, a countermeasure system includes an expandable countermeasure having a flexible body with a number of weighted projectiles attached around a perimeter of the body. A threat detection and launch control system detects incoming threats and, in response, triggers a launch of the expandable countermeasure from the launcher to intercept and neutralize the threat.

Expanding countermeasure and launcher system

A non-pneumatic tire and wheel assembly incorporates a tire tread and a conventional vehicle wheel with an elastomer tire body element and integral wall elements extending radially inward from the tire body element for sealing engagement with the wheel. The tire body element includes multiple concentric layers with alternating spokes. A bonded multilayer cover may be employed which is received within a recess in an outer surface of the tire body element from the tire tread. An attachment plate is engaged to the cover and attached to the wheel.

Non-pneumatic survivable tire mounting system for conventional wheels

A non-pneumatic tire and wheel assembly incorporates a tire tread and a conventional vehicle wheel with an elastomer tire body element molded for engagement intermediate the tread and wheel. The tire body element includes multiple concentric layers with alternating spokes. A bonded multilayer cover may be employed which is received within a recess in an outer surface of the tire body element from the tire tread. A mounting plate is engaged to the cover and attached to the wheel.
