Abstract:
Example aspects of a deployed electromagnetic radiation deflector shield assembly and a method for using a deployed electromagnetic radiation deflector shield are disclosed. The deployed electromagnetic radiation deflector shield assembly can comprise a base station on a ground surface; a deployed electromagnetic radiation deflector shield comprising an electromagnet configured to generate a magnetic field configured to deflect radiation from a radiation source; and an upright supporting the deployed electromagnetic radiation deflector shield at a distance away from the base station, and wherein the distance is configured to prevent the magnetic field from interfering with the base station.
Abstract:
A multi-functional composite structure has a modular design that can be altered depending on an extreme environment in which the structure will be exposed such as hazardous radiation, micro-meteoroid and orbital debris impacts, extreme temperature changes, etc. The material combinations employed in the multi-functional composite structure provide a supporting structure with low weight and maximum protection from radiation, debris impacts and temperature variations.
Abstract:
In some aspects, this disclosure relates to improved Z-grade materials, such as those used for shielding, systems incorporating such materials, and processes for making such Z-grade materials. In some examples, the Z-grade material includes a diffusion zone including mixed metallic alloy material with both a high atomic number material and a lower atomic number material. In certain examples, a process for making Z-grade material includes combining a high atomic number material and a low atomic number material, and bonding the high atomic number material and the low atomic number together using diffusion bonding. The processes may include vacuum pressing material at an elevated temperature, such as a temperature near a softening or melting point of the low atomic number material. In another aspect, systems such as a vault or an electronic enclosure are disclosed, where one or more surfaces of Z-grade material make up part or all of the vault/enclosure.
Abstract:
A system is configured to shield an interior chamber of a structure. The system may include a power source, an outer shield assembly operatively connected to the power source and coupled to an outer wall of the structure, and an inner shield assembly surrounding the internal chamber. The outer shield assembly generates a magnetic field through and around the structure. The inner shield assembly deflects radiation particles away from the interior chamber and re-directs portions of the magnetic field around the interior chamber.
Abstract:
A method for fabricating a carbon fiber composite part, for example, a sun shield structural assembly on a satellite. The composite part is fabricated on a carbon fiber/bismaleimide (BMI) composite tool, where a moisture barrier is positioned on the tool prior to carbon fiber part ply layers being positioned on the tool to prevent moisture from the tool from entering the part. In one embodiment, the moisture barrier includes cross-wise strips of aluminum foil. A wrinkle barrier is positioned on the moisture barrier before the carbon fiber part ply layers so that anomalies or wrinkles in the moisture barrier are not transferred to the part layers.

A processing and delivery system is in space around a celestial body having a magnetic field. The system includes at least one facility having supplies and configured for in-space recycling and manufacturing to produce processed objects utilizing space debris objects and the supplies. The system includes at least one space vehicle configured to deliver the space debris objects from their orbits to the at least one facility using electrodynamic propulsion. The system includes at least one space vehicle configured to deliver new supplies to the at least one facility from other orbits using electrodynamic propulsion. The system includes at least one space vehicle configured to deliver the processed objects from the at least one facility to their destination orbits using electrodynamic propulsion.
Abstract:
A spacecraft may include a module structure having a plurality of module sides. The spacecraft may include a central cylinder extending through a center of the spacecraft. The central cylinder may be the only closed cross-section extending along a longitudinal axis of the spacecraft.
Abstract:
Radiation shields include an outer composite wall, an inner composite wall, and an enclosed fuel chamber disposed between the inner and outer composite walls. A fuel may be contained within the enclosed fuel chamber. Spacecraft include one or more such radiation shields, and may further include a fuel cell and a conduit providing fluid communication between the fuel chamber of the radiation shield and the fuel cell. Methods of forming a radiation shield system include forming an enclosed fuel chamber between an outer composite wall and an inner composite wall of a radiation shield, and providing fuel within the enclosed fuel chamber.
Abstract:
The device for thermal monitoring for a piece of equipment, whereby said piece of equipment is integrated on a craft placed in a forced vacuum environment, an outside part (7) of the equipment projecting outside of a wall (3) of the craft and being subjected to a solar radiation flux (15), comprises an absorbent screen (13) that is suitable for being placed between the outside part (7) of the equipment and the wall (3) of the craft, whereby this absorbent screen (13) has—on at least one portion of its front face, designed to be placed on the side removed from the wall of the craft—an absorptivity αSOLAR that is the largest possible in the field of solar radiation, coupled to a low emissivity εIR in the infrared spectrum. The absorbent screen (13) is made of a very heat-conductive material and has—on at least a portion of its rear face, suitable for being oriented toward the wall of the craft—a high emissivity εIR in the infrared spectrum, typically greater than or equal to 0.7.
Abstract:
An In Orbit Transportation & Recovery System (IOSTAR™) (10) is disclosed. One preferred embodiment of the present invention comprises a space tug powered by a nuclear reactor (19). The IOSTAR™ includes a collapsible boom (11) connected at one end to a propellant tank (13) which stores fuel for an electric propulsion system (12). This end of the boom (11) is equipped with docking hardware (14) that is able to grasp and hold a satellite (15) and as a means to refill the tank (13). Radiator panels (16) mounted on the boom (11) dissipate heat from the reactor (19). A radiation shield (20) is situated next to the reactor (19) to protect the satellite payload (15) at the far end of the boom (11). The IOSTAR™ (10) will be capable of accomplishing rendezvous and docking maneuvers which will enable it to move spacecraft between a low Earth parking orbit and positions in higher orbits or to other locations in our Solar System.
