Aeronautical Technology Research Environment-Conscious Aircraft Technology Program

Environment-Conscious Aircraft Technology Program (ECAT)

To aim to attain an environment-friendly aircraft

While 2.6 billion people traveled by air in 2010, and air transportation is estimated to support 56.6 million jobs as well as economic activity equivalent to 3.5% of the world’ s GDP*1, air traffic volume is estimated to increase 2.6-fold in the next 20 years*2. As a result, there are growing concerns about the increasing environmental impact of aircraft, such as CO2 emissions and noise around airports. Therefore, there are greater needs than ever for environmentally friendly aircraft. In civil aviation, environmental performance is becoming one of the most important indicators for determining market competitiveness.

Based on past research and development achievements and in cooperation with industry and other stakeholders, JAXA ’s ECAT program conducts R&D on 1) high efficiency technologies such as for advanced ultra-high bypass ratio engine as well as aircraft drag and weight reduction, 2) noise reduction technologies for landing gear, high-lift devices, and engines, and 3) technologies to reduce aircraft emissions such as nitrogen oxides (NOx). This program aims to contribute to the realization of an environmentally sustainable and prosperous society and to the growth of the Japanese aviation industry while enhancing its international competitiveness.

Environment-Conscious Aircraft Technology Projects

FQUROH (Flight Demonstration of Quiet Technology to Reduce Noise from High-lift Configurations) project

The purpose of the FQUROH mission is to reduce airframe noise, a large fraction of which comes from high-lift devices (flap and slat) and landing gears, and to verify the feasibility of practical application of airframe noise reduction technologies through flight demonstration.

aFJR (Advanced Fan Jet Research) project

We are planning to undertake joint efforts with the Japanese aviation industry in developing next-generation jet engines with technologies that can increase the environmental compatibility of "fan" and "low-pressure turbine" components, which is a field of expertise of Japanese jet engine manufacturers, helping them to secure firm and expanding roles in design and manufacturing responsibilities associated with international collaborative projects.
