Abstract
An ultra-small probe which was named Shinen2 will be launched a H2A rocket with JAXA's asteroid probe the Hayabusa2. The Kyushu Institute of Technology has been developing the Shinen2 system with Kagoshima University. The purpose of this Shinen2 development is the establishment of a deep space communication method and a new structure designing method using a carbon fiber reinforced thermoplastics (CFRTP). Prairie View A&M University and NASA had developed a complementary metal oxide semiconductor (CMOS) sensor which can measure the three-dimensional distribution of the space radiation, was equipped in the Shinen2. This paper describes new deep space communication method and new structure designing method for the Shinen2. Furthermore, the CMOS type space radiation sensor is also described. The Shinen2 is the first small deep-space probe in the world to use an application of Carbon Fiber Reinforced Thermo-Plastics (CFRTP) for structure. A Carbon Fiber Reinforced Plastics (CFRP) is widely used in the aerospace industry. This CFRP has been used for satellite structures, and includes advantages such as high strength, high ductility, welding possibility, reduction of machining time. However, the example that used the CFRTP in structure of an aerospace vehicle is not found, the Shien2 will be the first example that it adapted to structure materials. This paper describes a summary of the Shinen2 structure that applied CFRTP.
