Aeronautical Technology Research

Aviation is an integral part of social infrastructure indispensable to our daily lives.
JAXA is mainly focusing on promoting research and development of new “environment-friendly” and “safe” technology necessary for future aviation transportation in cooperation with industries, universities, and overseas organizations based on the policy of the Japanese government and social needs.

About Aeronautical Technology Research

Environment-Conscious Aircraft Technology Program

JAXA's ECAT program, in collaboration with industry and other stakeholders, builds on the results of our previous research to pursue 1) high-efficiency technologies such as advanced ultra-high bypass ratio engines and aircraft weight and drag reduction, 2) noise reduction of airframe components (landing gear and high-lift devices) and engines (fan and jet exhaust), and 3) reducing emissions such as nitrogen oxides (NOx). The ECAT program will contribute to creating an environmentally sustainable and prosperous society and will support the growth of the Japanese aviation industry while enhancing its competitiveness.

Safety Technology for Aviation and Disaster-Relief Program

One project of the STAR program aims to realize weather safety avionics for next-generation passenger aircraft by developing a gust response/load alleviation system to reduce suppress wing vibrations and motions induced by turbulence. This project will help to prevent a major cause of in-flight accidents and incidents as well as boosting the competitiveness of the Japan's equipment manufacturers.
JAXA is pursuing the development of a disaster relief aircraft operations control system to make safer and more effective use of disaster relief aircraft assets. The system includes satellite observation and communication for greater efficiency and information management capability. JAXA is also developing technologies to expand the use of unmanned aircraft in disaster relief operations.

Sky Frontier Program

Due to its high speed and mobility, air transportation has become an essential means of long-range transport and an indispensable asset in search and rescue. In future, society expects air transportation to become not only more environmentally friendly but also faster and more convenient, usable from any place at any time.
To satisfy these diverse expectations and demands, JAXA's Sky Frontier program is challenging the frontiers of air transportation with researches with a long-term outlook.

Fundamental Aviation Technology

To support projects and research activities by JAXA and its stakeholders in relevant industries, JAXA creates scientific and technical knowledge to further enhance its world-leading experimentation and analytical capabilities in the fields of aviation and space, and transfer the results as Japan's common intellectual property to wider users. For these purposes, JAXA conducts scientific and basic research of aerodynamics, materials and structures, numerical analysis, and flight mechanics as well as maintaining and improving Japan's large-scale R&D facilities and flight demonstration capabilities using experimental aircraft.
