Performance test for jet engines under high altitude conditions

This facility handles altitude tests which is a jet engine operational test performed under high altitude conditions. In the test chamber, a decompression (low air pressure) environment of up to around 25 kPa can be maintained by installing a blower in the back stream. The blower can blow air at up to around 20 kg/s. The engine intake, which is the sample, can control pressure in a low air pressure environment from 0.6 MPa, and the temperature can be heated up to 150°C owing to the intake heater. In addition, a small air cooler is installed on the side of the sample intake. It is also possible to introduce a maximum heat drop of -60°C for an airflow rate of up to 1 kg/s into the sample intake. This facility is able to continually conduct operational tests on engines.
