Details of Sustainability Topics

Taiyo Nippon Sanso Corporation (TNSC), Kyushu University Research Institute of Advanced Electric Propulsion Aircrafts, the National Institute of Advanced Industrial Science and Technology (AIST), and several companies have jointly developed a high-efficiency, high-output electric propulsion system utilizing superconducting technology for next-generation aircraft in a project commissioned by the New Energy and Industrial Technology Development Organization (NEDO). The development group has been developing technologies for predicting and reducing alternating current losses in superconducting wire and for increasing current capacity. By applying these technologies, the group has developed a fully superconducting motor that uses superconductors for both the field winding and the armature winding. Combining this with a cooling system that circulates liquid nitrogen using a pump, the group successfully conducted the world’s first rotational test of this type of motor. This achievement is a significant step forward in realizing electric propulsion and next-generation aircraft. The group will continue development for practical application and aims to apply the system for flying cars as well.
