US 6,550,209 B2 · Modular deployable antenna

Abstract

Disclosure provides a transformable linked structure, a deployable diagonal structure, a plane stowage-type deployable truss and a line stowage-type deployable truss with high rigidity and reliability constituted by the above-described transformable linked structure and the above-described deployable diagonal structure, and also provides a plane/line stowage truss structure extremely approximated to a spherical surface using the two types of deployable trusses. The present disclosure discloses a module linked structure for linking deployable trusses securely and a holding/releasing mechanism for realizing reliable holding and release. Further, the present invention provides a modular deployable antenna with high precision even if it is large-sized which is realized by spreading mesh on the plane/line stowage truss structure.

Dependent claims

A line stowage-type deployable truss comprising:

first even horizontal members forming a even-numbered polygon on one side;
second even horizontal members forming a even-numbered polygon on the other side;
and
even longitudinal members, each having both ends connected to vertices of the even-numbered polygon on one side and the even-numbered polygon on other side thereby forming even sides;
wherein
each of said first and second horizontal members is coupled to each of said even longitudinal members to sway along a plane of each side;
at least every other side comprises a transformable frame;
and
deployable/stowing operation is performed as a whole in such a way that said even longitudinal members separate and approach each other.
