Advanced high-temperature material and mutifunctional structure technology

In order to reduce fuel consumption of aero-engines, it is vital to improve thermal efficiency. Accordingly, it is essential to enhance the heat-resistance of material used in high-temperature areas.

For example, in current aero-engines, nickel-base super alloy is used in high-pressure turbine blades. Although the alloy is protected by a heat-resistant coating and cooling system, it is not feasible for the use at higher temperature due to its maximum durable temperature.

In response, JAXA aims to realize advanced high-refractory materials for hot section parts (high-pressure turbine parts, etc.) of aero-engines.
JAXA also researches fundamental characteristics of shape memory alloys and additive manufacturing materials for multifunctional engine structures.
