“…But the stowed height of it is fairly big; this key disadvantage limited its applications in much larger deployable reflectors. The <l> 18m mesh antenna on Terrestar-l satellite uses a new kind of deployable reflector structure scheme [1]. It mainly uses six folded scissors ribs as its backbone, so it can be called "folded scissors rib reflector".…”

New large deployable mesh reflectors are frequently used recently. Here we propose a new simplified large deployable reflector structure, with lower surface density and better package ratio both in radial direction and in height direction. Its surface modeling manner is fairly simple.Conceptual design of such a new simplified large deployable reflector structure is described. Deploying ability analyses of the structure with 30m diameter show that the structure can be deployed successfully. Surface precision analyses of the deployed structure show that it has potential to reach surface precision demand. A deploying test of a small deployable model with 3m diameter shows the deploying ability of the backbone. Such a new simplified large deployable reflector structure has potential to be used in future large deployable reflectors in space applications.

“…This demand quickly appears in space applications. Therefore, some new kinds of lightweight large deployable mesh reflectors are frequently used in recent years, such as the 18m diameter mesh antenna on Terrestar-1 satellite launched on July 7, 2009 [1], and the 22m diameter mesh antenna on Skyterra-1 satellite launched on November 15, 2010 [2]. They are with much lower surface density, meanwhile with much lower cost than previous designs such as the well known older mature AstroMesh reflectors [3,4].…”

Continuous affordability is a new demand for space applications, therefore, some new kinds of lightweight large deployable mesh reflectors are frequently used in recent years. Here we make system design and simulation of a new kind of space large deployable reflector antenna that we proposed recently. System design shows its several superior outstanding advantages. Simulations of deploying ability, surface precision, and antenna performance, all reveal that such kind of deployable antenna has potential foreground in future space applications.

“…Deployable structures have been widely applied to the aerospace industry [1][2][3], such as aperture antennas [4][5][6][7][8], solar arrays [9,10], space masts [11,12], and so on. One of the most important advantages is the perfect package property [13] of deployable structures so as to store in the fairing of launch vehicle and deploy into structures in orbit.…”

Structural Dynamic Improvement for Petal-Type Deployable Solid-Surface Reflector Based on Numerical Parameter Study

Petal-type Deployable Solid-surface Reflector (PDSR) is a kind of important structure widely applied in deployable reflector antennas in aerospace engineering. The dynamic properties of this reflector structure in deployed state are significant to the reflector accuracy for antennas. However, the study of the dynamic evaluation of deployable structure with revolute joints is difficult and seldom concerned by researchers. In order to study dynamic properties of the PDSR, the Cable Replacement Method (CRM) was utilized to equivalently simulate the nonlinear structural stiffness of the revolute joint for numerical analyses. The Finite Element Model (FEM) of this reflector structure was established by commercial software ANSYS (ANSYS Inc., Canonsburg, PA, USA) and verified by the theoretical analysis and dynamic test of actual prototype model. The natural frequencies and mode shapes of deployed reflector were computed to study the influence of drag spring design parameters as stiffness, pre-tensioned force, and distance of two adjacent linkage butts. Finally, the analysis results were concluded that the drag springs between two adjacent petals can essentially improve the dynamic performance of reflector structure in deployed state. It can be a useful technical system for future engineering applications of PDSR antennas.
