The invention is directed to deployable reflectarray antenna structure. In one embodiment, the deployable reflectarray antenna structure includes a pair of flexible electrical elements, a feed antenna, and a deployment mechanism that employs a plurality of tapes to respectively transition the pair of flexible electrical elements from an undeployed state in which the elements are folded towards a deployed state in which the deployment mechanism and electrical elements cooperate to form a reflectarray and a subreflector of a reflectarray antenna structure. Further, the deployment mechanism also operates to position the reflectarray and subreflector relative to one another and to the feed antenna so as to realize a reflectarray antenna structure.

Deployable antenna structure

A deployable structure for use in establishing a reflectarray antenna is provided that includes a flexible reflectarray and a deployment structure that includes an endless pantograph for deploying the flexible reflectarray from a folded, undeployed state towards a deployed state in which the flexible reflectarray is substantially planar. In a particular embodiment, the deployment structure includes a plurality of tapes that engage the endless pantograph and are used to establish a positional relationship between the deployed reflectarray and another component of the reflectarray antenna.

An explosive detonating system comprises connectable components to connect/disconnect a pathway that ignites an explosion. A firing actuator activates primers. An adapter connects the firing actuator to shock tube and channels the ignition force from the primers into the shock tube. A cap box houses blasting caps coupled to the end of the shock tube. A priming well is coupled to the cap box/blasting caps and detonating cord. When the firing actuator is initiated, the percussion caps ignite, sending an explosive jet of gas into the shock tube, which ignites an explosive liner. An explosive wave travels through the shock tube and activates the blasting caps, which activate the detonating cord in the priming well. The explosive is placed in a location to provide a desired explosive effect. For example, the system may be employed as a system to breach into structures, remove obstacles and/or barriers, or other applications.

Explosive detonating system and components

A tape drive comprises a roll of a tape that can be extended from a rolled state to an extended state. The tape includes a rigid material that supports the tape and a pliable material disposed at least partially on one side of the tape. A compression roller is disposed on a side of the tape and is biased toward the tape. A drive roller is disposed on the other side of the tape. The drive roller comprises an uneven surface that mechanically engages the pliable material of the tape, without protruding through the tape, as a result of the bias of the compression roller forcing the tape toward the drive roller. A motor turns the drive roller to extend the tape from the roll as the protrusions of the uneven surface of the drive roller mechanically engage the pliable material of the tape as the drive roller turns.

An explosive detonating system comprises connectable components to connect/disconnect a pathway that ignites an explosion. A firing actuator activates primers (percussion caps). An adapter connects the firing actuator to shock tube and channels the ignition force into the shock tube. A cap box houses blasting caps coupled to the end of the shock tube. A priming well is coupled to the cap box/blasting caps and the detonating cord. When the firing actuator is initiated, the percussion caps ignite, sending an explosive wave into the adapter, which channels the wave into the shock tube and ignites the shock tube. The explosive wave travels through the shock tube and activates the blasting caps, which activate the detonating cord in the priming well. The explosive is placed in a location to provide a desired explosive effect. For example, the system may be employed as a system to breach structures or other applications.

A deployable prop is provided that is capable of transitioning from an undeployed state to a deployed state in which the prop can be used to support an object against or adjacent to a structural surface. In one embodiment, the deployable prop includes a bistable 'carpenter's' tape, a foot member that is engaged to one end of the tape, and a head member that is engaged to the other end of the tape. The tape, foot member, and head member can be placed in an undeployed state that has 'roll' shape and in a deployed state in which the tape extends substantially linearly between the foot and head members and can be used to support an object against or adjacent to a structural surface.

Deployable reflectarray antenna structure

A panel structure for use in a deployable and cantilevered solar array structure is provided. A panel includes first and second planar panel sections and an intermediate panel section connecting the first and second sections. The planar panel sections are capable of being situated with respect to one another so as to have a V-tent-like shape when the panel is in a deployed state and to be coplanar when the panel is in a stowed state. When in the V-tent-like shape, the intermediate section of the panel extends in a straight line that is collinear or parallel to the longitudinal axis of the cantilevered solar array structure when deployed. The V-tent-like shape produces A panel structure that has a relatively high moment of inertia, is stiff, and can provide a large area for supporting solar cells.

A Deployable Morphing Modular Solar Array (DMMSA) for deploying Deployable Morphing Modular Solar Power Assemblies (DMMSPAs) from a spacecraft is provided. The DMMSA comprises a Root Staging and Deployment Mechanism (RSDM) mounted to a spacecraft. A plurality of petal assemblies are rotatably secured to the RSDM with each petal assembly having at least DMMSPA secured thereon and each DMMSPA having a slight V-configuration. A launch restraint assembly stacks and sandwiches the petal assemblies prior to deployment with the launch restraint assembly pre-loading each petal assembly's one or more DMMSPA into a substantially flat configuration. Upon release of the launch restraint assembly, the stacked and sandwiched petal assemblies rotate relative to the spacecraft and each petal assemblies DMMSPA elastically morphs from the substantially flat configuration into the slight V-configuration.
