Cable-Stiffened Pantographic Deployable Structures Part 2: Mesh Reflector
The general concept of deployable structures based on pantographs that are deployed and stiffened by means of cables is applied to the design of the support structure for a large mesh re ̄ ector. The two main components of this structure are a cable-stiffened pantographic ring that deploys and pretensions a cable network that, in turn, provides a series of stiff, geometrically accurate support p...
متن کاملUltra Thin Deployable Reflector Antennas
We have recently proposed a new concept for deployable reflectors consisting of a thin parabolic carbon-fibre-reinforced-plastic (CFRP) shell stiffened along the edge by an elastically collapsible stiffener. Here we show that a stiffener accounting for less than 10% of the total mass of the reflector increases the stiffness of the softest deformation mode of the deployed reflector by 48 times, ...
متن کاملLarge Aperture , Solid Surface Deployable Reflector
Composite Technology Development Inc. (CTD) is currently funded through the NASA Advanced Component Technology (ACT) program to develop an off-set fed, TEMBO continuous composite surface deployable reflector for earth science applications. This type of reflector will offer a parabolic surface with the accuracy needed for RF science measurements to Ka band and beyond, including a clean aperture ...
متن کاملCookies Along Trust-Boundaries (CAT): Accurate and Deployable Flood Protection
Packet floods targeting a victim’s incoming bandwidth are notoriously difficult to defend against. While a number of solutions have been proposed, such as network capabilities, thirdparty traffic scrubbing, and overlay-based protection, most suffer from drawbacks that limit their applicability in practice. We propose CAT, a new network-based flood protection scheme. In CAT, all flows must perfo...
