A small, expendable EDT package is under development that consists of a bare conductive tether and Field Emitter Cathodes (FECs) that utilize carbon nanotubes. In this paper, precise numerical simulations are performed for some aspects of mission analysis, such as available electric currents, orbital changes, tether stability, and deployment dynamics. A tether is modeled as a lumped mass to take into account tether flexibility, and environment models (changes in the plasma density and geomagnetic field, and so on) are also considered. Test manufacture of the tether is conducted, and measured parameters of the manufactured tether are reflected in the numerical simulations.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
