The jet engine test facility has an engine test cell that can operate turbofan engines in a static conditions on the ground level. Various testings and demonstrations on aeroengine technologies can be performed using an engine test bed installed inside an engine test cell.
JAXA has a range of testing facilities essential for aeronautics, such as wind tunnels, research aircraft, aeroegine test facilities, composites test facilities and supercomputer. Some test facilities are available to external users.
Aeroengine test facilities
Aeroengine test facilities are used to conduct ground tests of a jet engine’s constituent modules such as fans, compressors, and combustors in various conditions. Some facilities are available to external users.
The altitude test facility simulates high-altitude flight on the ground, enabling researchers to test engine performance under replicated flight conditions. Originally built in 2001 to test a turbojet engine in supersonic flight condition, the facility has been upgraded in FY2020 to enable tests in wider flight conditions.
Consisting of two types of circuit, a high-pressure test rig and a low-pressure test rig, this facility is used to test the components of fans and compressors. Each circuit are driven by electric motors and has a gear box that rotate at high speed to generate compressed air in the circuit.
This facility is to test combustors and its components under a high-temperature and high-pressure conditions for precise analysis of combustion phenomena, emissions etc. The facility consists of two types of high-pressure test rigs (type A and B) for up to 5.0MPa, and a pressurized test rig for up to 1MPa.
This facility can test aeroengine’s annular combustor under high-pressue high-temperature conditions for evaluation of combustion phenomena and emissions.
Aeroengine structures and materials test facilities
These facilities are used to gather data for developing new structures and materials for jet engine components.
Noise test facilities
- anechoic chamber
- anechoic wind tunnel
An anechoic chamber offers an environment for measuring noise and exhaust from non-heated jets, while an anechoic wind tunnel is being used to test aerodynamic noise and noise from heated jets.
