Research on Aeronautical Technology Sky Frontier Program

Sky Frontier Program (Sky Frontier)

Air transportation systems with speed and mobility are indispensable to our society, and need to meet the evolving demands as we shift toward a sustainable society. While there are demands for faster and more accessible air transportation systems that can fly faster and farther from anywhere at any time, the emergence of innovative systems that enable drastic improvements in environmental performances are also required to achieve the Sustainable Development Goals (SDGs).

The Sky Frontier Program is designed to address these diverse requirements by promoting research and development activities from long-term perspectives, thereby opening up new potentials of air transportation and pushing the boundaries of aviation. With major research themes on supersonic transport, hypersonic transport, and electric and hybrid aircraft systems, the Sky Frontier Program creates innovative aircraft concepts and key enabling technologies to bring about innovation in air transportation systems.

Silent supersonic transport technology

Following the completion of the D-SEND project(FY2010-FY2015), which successfully demonstrated the validity of our unique sonic boom reduction technology in the form of flight test for the first time in the world, we are now working on integrated design technologies that satisfy multiple design requirements simultaneously — low noise during takeoff and landing and lighter airframes, in addition to low sonic boom and low drag.

Emission free aircraft technology

JAXA has been promoting studies on electric and hybrid aircraft for drastic reduction of CO2 emissions in aviation. Our ongoing studies mainly address themes around hybrid propulsion systems, such as electric generator system having combined cycle of fuel cell and gas turbine and distributed electric fan system.
