| 18 | Improvement of sail storage and deployment mechanism for spin-type solar power sail显示文摘Deployable membrane structures are expected to be used for large area space structures,such as solar propulsion sails,magnetoplasma sails,drag-deorbiting sails,membrane antennas,and solar power sails.They are lightweight and can be compactly stored at launch.One achievement of the Japan Aerospace Exploration Agency(JAXA)was the successful deployment of a 200 m2 sail using centrifugal force in the IKAROS mission,which was the first solar propulsion sail-craft in history.JAXA has long been studying the technology of spin deployment of sail membranes,and is currently planning the spin deployment of a class sail larger than 2000 m2 as the next step in the development of the IK AROS technology.This paper discusses the unexpected behaviors during on-orbit sail deployment by IKAROS,as well as problems with the sail holding method,and proposes an improved sail storage structure and deployment mechanism for the OKEANOS mission. | Osamu Mori Nobukatsu Okuizumi Toshihiro Chujo Yuki Takao | 2020 | Astrodynamics2020，4，3： | 0 |
| 19 | Influence of thin-film device with curvature on natural frequency of rectangle membrane under uniaxial tension显示文摘A solar power sail demonstrator“IKAROS”demonstrated solar sailing technology in 2010.The membrane of the spinning solar sail IKAROS is estimated to be deformed toward the Sun.The deformation was kept even under low spin-rate.Previous studies suggest that curvature of thin-film solar cells on the membrane increases the out-of-plane stiffness by finite element analysis.Shape,out-of-plane stiffness,and natural frequency of membranes have to be predicted for solar sails with thin-film devices,such as thin-film solar cells,dust counters,and reflectivity control devices in order to reduce the margins of sail size and propellant mass against disturbance solar pressure torque acting on the membrane.In this paper,the effect of a curved thin-film device on the natural frequency of a rectangle membrane under uniaxial tension was investigated.Three types of membranes were evaluated:a membrane with a curved thin-film device,a membrane with a flat thin-film device,and a plane membrane.Geometric nonlinear finite element analysis and eigenvalue analysis were conducted to investigate the natural frequencies under varying tension.The simulations were verified by vibration experiments.It was found that under low tension,the natural frequency of the membrane with the curved thin-film device is significantly higher than that of the others and that under high tension,the natural frequency of the membrane with the thin-film device is slightly lower than that of the plane membrane.In addition,parametric analysis on the curvature of the thin-film device shows that natural frequency at low tension is sensitive to the curvature.The eigenvalue analysis of a whole solar sail with the curved thin-film devices also suggests that the curvature remarkably affects the vibration modes.In conclusion,curved thin-film devices have a significant impact on the out-of-plane stiffness of a membrane under low tension. | Masanori Matsushita Nobukatsu Okuizumi Yasutaka Satou Osamu Mori Takashi Iwasa Saburo Matunaga | 2019 | Astrodynamics2019，3，3： | 0 |
| 20 | Evaluation of excavation damaged zones(EDZs)in Horonobe Underground Research Laboratory(URL)显示文摘Excavation of underground caverns,such as mountain tunnels and energy-storage caverns,may cause the damages to the surrounding rock as a result of the stress redistribution.In this influenced zone,new cracks and discontinuities are created or propagate in the rock mass.Therefore,it is effective to measure and evaluate the acoustic emission(AE)events generated by the rocks,which is a small elastic vibration,and permeability change.The authors have developed a long-term measurement device that incorporates an optical AE(O-AE)sensor,an optical pore pressure sensor,and an optical temperature sensor in a single multi-optical measurement probe(MOP).Japan Atomic Energy Agency has been conducting R&D activities to enhance the reliability of high-level radioactive waste(HLW)deep geological disposal technology.In a high-level radioactive disposal project,one of the challenges is the development of methods for long-term monitoring of rock mass behavior.Therefore,in January 2014,the long-term measurements of the hydro-mechanical behavior of the rock mass were launched using the developed MOP in the vicinity of 350 m below the surface at the Horonobe Underground Research Center.The measurement results show that AEs occur frequently up to 1.5 m from the wall during excavation.In addition,hydraulic conductivity increased by 2e4 orders of magnitude.Elastoplastic analysis revealed that the hydraulic behavior of the rock mass affected the pore pressure fluctuations and caused micro-fractures.Based on this,a conceptual model is developed to represent the excavation damaged zone(EDZ),which contributes to the safe geological disposal of radioactive waste. | Koji Hata Sumio Niunoya Kazuhei Aoyagi Nobukatsu Miyara | 2024 | Journal of Rock Mechanics and Geotechnical Engineering2024，16，2： | 0 |
