Embodiments of the present disclosure relate to a structure that comprises at least one layer of air beams that define an interior space of the structure wherein laterally adjacent air beams are configured to laterally abut each other. Optionally the structure comprises at least a first layer of a plurality of air beams and a second layer of a second plurality of air beams, wherein the second layer is positioned adjacent to and interior to the first layer for defining an interior space of the protective structure. A structure with laterally abutting air beams may better protect the occupants and contents within the structure from the effects of an explosion. Constructing a structure with at least two layers of air beams may provide a stiffer structure as compared to a structure that is constructed from a single layer of air beams.

A temporary maintenance enclosure for the maintenance of at least part of a turbine blade, said enclosure comprises a number of side walls which substantially surround the circumference of a blade in need of maintenance; and a roof extending from said side walls towards said blade; wherein said roof comprises an aperture through which said blade is received.

A temporary maintenance enclosure for the maintenance of at least part of a turbine blade, the enclosure comprises a platform arranged, in use, to border at least part of the circumference of a blade in need of maintenance; at least one wall and a roof which are carried by the platform; the at least one wall extending from the platform; wherein said roof extends from the wall towards the blade; and wherein the enclosure further comprises a flexible sheath which seals onto the blade to provide a sealed volume for maintenance of said blade.

Vehicle awnings comprise an inflatable frame assembly comprising a main frame member that defines a space, a left supporting frame member, and a right supporting frame member; a canopy operatively coupled to the main frame member and spanning the space; and an attachment system for attaching the vehicle awning to a vehicle.

The document concerns inflatable tents, in particular non-durable, inflatable tents. The tents are provided with an inflated arch and a flysheet. The arch can be simply constructed from first and second flexible sheet materials joined to one another, and the flysheet is pivotally openable about the arch.

A protective device is described having a membrane and a support device for the membrane, wherein the support device has an inflatable first support element with a flexible wall which forms a first pressure chamber. The first support element has a first connection port with a first connection opening. The support device has an inflatable second support element with a flexible wall which forms a second pressure chamber. The second support element has a second connection port with a second connection opening. A connection device for connecting the first connection port to the second connection port is provided, wherein the connection device has a first connection part for connecting to the first connection port and a second connection part for connecting to the second connection port. The protective device is characterised in that means are provided for connecting the first and second connection parts to one another in a detachable manner.

A modular mobile temporary structure is provided with a plurality of primary modules. Each module includes a housing formed utilizing an intermodal shipping container, with the plurality of primary modules forming a base and an outside periphery of a temporary structure. A lightweight pneumatic frame consists of multiple inflatable elements, and a sealing tent. The pneumatic frame forms a dome of the temporary structure, and the inflatable elements are connected to each other and to the base. The sealing tent interconnects the inflatable elements and covers an exterior of the temporary structure to protect an interior of the structure from atmospheric factors.

An airform that can be inflated, for example, for facilitating construction of a structure is provided. The airform may include a first portion, a second portion, or multiple other portions, and reinforcement. The first portion may, for example, be configured to be disposed in a first orientation, such as vertically or in a radial profile, when the airform is inflated. The second portion transitioning from the first portion may be configured, for example, to assume an alternate shape and profile, such as a radial shape and profile, when the airform is inflated. The reinforcement may, for example, be provided at a portion of the airform that defines a transition from the first portion to the second portion.

A protective device is described having a membrane and a support device for the membrane, wherein the support device has an inflatable first support element with a flexible wall which forms a first pressure chamber. The first support element has a first connection port with a first connection opening. The support device has an inflatable second support element with a flexible wall which forms a second pressure chamber. The second support element has a second connection port with a second connection opening. A connection device for connecting the first connection port to the second connection port is provided, wherein the connection device has a first connection part for connecting to the first connection port and a second connection part for connecting to the second connection port. The protective device is characterised in that means are provided for connecting the first and second connection parts to one another in a detachable manner.

A tethermast and frag wall includes a fabric device having a fill volume fillable with a fill material on a flexible or compliant mast system. The fill volume may be a chambered curtain. The tethermast and frag wall is self supporting, easily deployed, and may be used in connection with a structure or may be deployed stand-alone. A tether system for an air beam structure utilizing a flexible tethermast, an external frag wall or frag curtain, soft couplings, air beam slings, or combinations thereof to reduce the effects of pressure waves, such as blast waves, onto and into an air beam structure and any inhabitants.
