Invested in a start-up company for flexible space structures such as membranes

Taiyo Kogyo Corporation (Tokyo headquarters: Setagaya-ku, Tokyo; Osaka headquarters: Yodogawa-ku, Osaka; President: Yumi Nomura), a company involved in large-scale membrane structures (tent structures) and civil engineering and logistics materials, has invested in cosmobloom Corporation (Ota-ku, Tokyo; Representative Director: Momoko Fukunaga; hereinafter “cosmobloom”), a company that conducts analysis, design and development related to space structures using flexible structures such as membranes and cables (hereinafter “gossamer structures”). (Ota-ku, Tokyo; President: Momoko Fukunaga; hereinafter “cosmobloom”), which is engaged in the analysis, design, and development of space structures using flexible structures such as membranes and cables (hereinafter “gossamer structures”). Taiyo Kogyo will promote joint research and development with cosmobloom, and will also discuss with the company the possibility of future manufacturing and sales.

The structure consisting of thin, lightweight, flexible components such as membranes and cables is called gossamer structure, and has long been noted as a structural style of spacecraft. It is lightweight, deployable, and storable, and can be folded into small pieces and transported into space. On the other hand, the extremely flexible structure has the drawback that its behavior is difficult to predict. CosmoBloom uses a unique analysis technology called NEDA (Nonlinear Elasto-Dynamic Analysis code) to predict this behavior. This technology is actually used in the film deployment simulation of IKAROS, a small solar power sail demonstrator launched by JAXA in 2010.

CosmoBloom was formerly known as the Miyazaki Laboratory, Department of Aerospace Engineering, College of Science and Engineering, Nihon University (now the Space Structure Systems Laboratory of JAXA). NEDA, developed by Cosmobloom technical advisor Professor Yasuyuki Miyazaki (Professor at JAXA Institute of Space and Astronautical Science / Specially Appointed Professor at Nihon University), has been used in the simulation of IKAROS membrane expansion, and in the design, development and evaluation of various gossamer structures such as spin expansion membrane, flat trusses using self-extending booms and three-dimensional trusses. The system is also used in the design, development, and evaluation of various gossamer structures such as spin expansion membranes, planar trusses with self-extending booms, and 3D trusses. Miyazaki Laboratory has been developing nano-satellites under the leadership of students since the 2000s. We have developed and operated a total of four nano-satellites, SEEDS (2006), SEEDS-II (2008), SPROUT (2014), and NEXUS (2019), and all of the founding members of Cosmobloom have experience in the design, development, manufacturing, testing, and operation of nano-satellites This is one of CosmoBloom’s strengths.

Taiyo Kogyo, under the collaboration agreement signed between the National Aerospace Laboratory of Japan (JAXA), Tokyo University of Science Educational Corporation, and Shimizu Corporation, has started the “Space Colony Demonstration Module” (photo below) to verify the space habitat created in 2019, and has been working on space-related We have started the verification to the business.
In 2021, the company participated in the technological research and development of the “Project for Promotion of Innovative Technology Development for Unmanned Space Construction” (in collaboration with the Ministry of Land, Infrastructure, Transport and Tourism and the Ministry of Education, Culture, Sports, Science and Technology) as part of the “Strategic Program for Acceleration of Space Development Utilization” (Stardust Program), and has been working on “construction of a ground demonstration model for the lunar inflatable habitat module” since 2022. The development is still ongoing.
