STAR – Safety Technology for Aviation and Disaster-Relief Program

Demands for aircraft with enhanced safety is increasing as the projected growth in air traffic also involve the risk of more accidents. Responding to frequent natural disasters and meeting the ever-diversifying needs in the field of crisis management as flexibly and quickly as possible, meanwhile, will require safer and more efficient use of both manned and unmanned aircraft.

The STAR program encourages R&D that makes aircraft operation safer and helps ensure the safety and security of society through the use of aircraft. Examples include detection, prediction, and prevention technologies to protect aircraft operations from the threats of special weather conditions (turbulence, snow and ice, lightning, and volcanic ash, etc.) and human error, which represent the major causes of aircraft incidents. Not only will the R&D thus make aircraft operation safer and more efficient, but technological transfers of the research outcomes will also benefit the international competitiveness of Japan's equipment manufacturers. Other focus areas include the R&D of integrated aircraft operation management systems for disaster relief and crisis management, which aims at improving the efficiency and safety of aerial capabilities in responding to natural disasters and managing crises (security and warning frameworks, for example) through the integrated and efficient use of aircraft, satellites, and other aerial assets. The effort also involves work on technologies for operation management and fl ight capability enhancement, which aim to make more effective use of helicopters and unmanned aircraft. All together, the program aims to help create a safer, more secure society on a far-reaching scope.

R&D of onboard safety avionics technology to prevent turbulence-induced aircraft accidents (SafeAvio)

By combining "Doppler LIDAR" that detects turbulence in advance with an automatic attitude control system for aircraft, JAXA is developing "airframe technology for turbulence accident prevention (weather safety avionics)" to suppress sudden shaking by turbulence

Airframe safety management technology

JAXA is developing "airframe safety management technology", a system that detects, predicts and administers the state of each airframe more effectively. The system can effectively sustain reliability of airframe safety against external factors, such as icing, lightning strikes, gusts of wind, hard landings, bird strikes, collision with foreign object and more.

Aircraft operation technology for disaster relief (D-NET2)

JAXA has been developing technlologies required for the implementation of the "Integrated aircraft operation system for disaster relief system", which is to contribute to safe and efficient operation of disaster relief aircraft and collection and sharing of disaster information through integrated operations of manned aircraft, unmanned aerial vehicles (UAVs), and satellites. In doing so, JAXA's goal is to contribute to strengthen the nation's ability to respond to future disasters.

Unmanned aircraft systems (UAS) and operation technology

By researching and developing basic technologies for improving the operational safety and mission capabilities of small UAS, JAXA is helping expand the scope of the technology and contributing to the realization of a safe and prosperous society.

Distributed and Revolutionarily Efficient Air-traffic Management System (DREAMS)

JAXA has researched and developed a novel air-traffic management system that is ready for future increases in air traffic, as well as a system that allows information sharing among numerous deployed relief aircraft and with a disaster-relief headquarters in the event of a large-scale disaster.
