The HCWT takes high-speed airflow as accelerant,aviation kerosene as fuel in the experiment, the high temperature jet stream which obtained in the combustion forms a uniform and stable temperature field around the specimen and simulates high-temperature test environment encountered in the specimen. In order to produce a uniform and stable temperature field, the test system of the HCWT is equipped with a control system, a fuel supply system, an air velocity system and a cooling system and so on.
