Introduction to Deployable Space

What is/are Deployable Space?

Deployable Space - Sensitivity analysis of these design parameters in the frame of multibody dynamics can serve as a powerful tool to evaluate and improve the dynamic performances of deployable space structures. ^[1] In this document, a new system for deployable space grids is proposed. ^[2] Origami, the ancient art of folding thin sheets, has attracted increasing attention for its practical value in diverse fields: architectural design, therapeutics, deployable space structures, medical stent design, antenna design and robotics. ^[3] Shape memory polymers (SMPs) have been applied in aerospace engineering as deployable space structures. ^[4] They have found use in deployable spacecraft structures, including booms and solar generators. ^[5] The classical scheme of petal type deployable space reflector was proposed and developed by Dornier Corporation within FIRST space project and was used in the Radioastron project to create a 10-meter antenna of space radio telescope. ^[6] This paper describes challenges and lessons learned throughout the concept, design, assembling, integrating, and testing for hardware and software of Virginia Tech (VT) ThickSat, a testbed for lightweight deployable space structures designed by engineering students at Virginia Tech. ^[7] Deployable spacecraft technology should be both lightweight and compact for storage while also being rigid and expansive once deployed. ^[8] A large number of deployable space structures involve multibody system dynamics, and in order to effectively analyze and optimize dynamic performance, the sensitivity information of multibody syste. ^[9] The synthesized EVA fiber with an excellent shape memory effect and a superior recovery stress is highly promising for various applications such as deployable space structures and fasteners, artificial muscle and self-finishing smart textiles, etc. ^[10] That may provide some references for optimization design of deployable space mechanisms considering clearance joints. ^[11] This paper aims at comparing possible mechanism layouts for a deployable space telescope designed for Earth observation in the infrared spectrum. ^[12] Andronov-Hopf bifurcations, Pomeau-Manneville intermittent chaos and nonlinear vibrations of the large deployable space antenna (LDSA) subjected to the thermal load with the case of 1:3 internal resonance are studied for the first time. ^[13] Actuators for deployable space antennas operating under temperatures around the liquid helium point (~4. ^[14] This article presents a high precise deployment mechanism for a deployable space telescope to facilitate satellite miniaturization. ^[15] A method of improving the positioning accuracy of deployable space structures using vibrations was developed, and its effectiveness was demonstrated. ^[16] Cable net structures are important in the construction of large deployable space antennas. ^[17] These programmable structures can provide practical solutions in various engineering applications, such as deployable space structures, portable architectures for disaster relief, reconfigurable packing materials, and medical devices such as stents. ^[18] The umbrella cable-net structure is one of the most popular forms for deployable space reflectors and has been successfully applied to many in-orbit deployable antennas. ^[19] Accordingly, the carbon fibre reinforced SMPCs can be used to produce deployable space habitats to fabricate on earth, compress and pack in a spacecraft, transport to an outer space location and ultimately deploy in to the original shape. ^[20] ABSTRACT Space masts are widely used in the aerospace engineering as one type of deployable space structures. ^[21] Shape memory polymers have been studied as the matrix of lightweight self-deployable space structures for decades. ^[22] The behavior of thin-ply composite at high bending curvatures and specifically studied for deployable spacecraft structure applications. ^[23] Single-frequency lasers are a key enabling technology for deployable space-based Differential Absorption Lidar (DIAL) and Wind Lidar systems. ^[24] To develop epoxy-based shape memory polymers (ESMPs) with a high switching temperature and good mechanical and shape memory properties for deployable space structures, the crosslink density and chain flexibility of the conventional epoxy resin, diglycidyl ether of bisphenol-A, were controlled by adding a flexible epoxy resin, diglycidyl ether of ethoxylated bisphenol-A with six oxyethylene units (DGEEBA-6). ^[25] These findings have the potential to advance the development of built-in control mechanisms in microfluidic networks, thereby facilitating the creation of portable systems and enabling novel applications in areas ranging from wearable healthcare technologies to deployable space systems. ^[26] Deployable space applications require them to be ultra-thin and hence generally made of one to six layers of thin-woven composites where out-of-plane behavior is dominant. ^[27] One challenging issue for realising future deployable space division multiplexing (SDM) systems is establishing reliable and robust signal transmission techniques in the presence of MDL. ^[28] The need for low-cost, mission-flexible, and rapidly deployable spaceborne sensors that meet stringent performance requirements pervades extreme weather monitoring programs focused on intense rainfall and cyclone forecasting. ^[29] In this work a shunted flexible piezoelectric damping system is designed and numerically evaluated for the purpose of vibration attenuation of large deployable space cable structures. ^[30] Due to its above advantages, several potential applications are proposed for deployable space structures and will be validated in near future. ^[31] Single-ply weave-reinforced shape memory polymer composites (SpWR_SMPCs) are promising materials for deployable space structures because they have high deformability, stiffness and strength and exhibit variable mechanical properties at different external temperatures. ^[32]
