Description

technical field [0001] The invention belongs to the field of air heating devices, in particular to an aero-engine ground direct-connection test air heating device. Background technique [0002] The direct connection test technology is a very critical technology in the research of aero-engine. The aero-engine direct connection test technology is to directly connect the aero-engine combustion chamber and the test device through a pipeline or a simulated throat on the ground. The airflow parameters at the same time, the inlet airflow parameters of the combustion chamber include flow rate, total temperature, total pressure and Mach number, and the Mach number of the inlet airflow is related to the structure. , when the inlet section is consistent with the actual flight, the Mach number of incoming flow is strictly guaranteed. [0003] Most of the aeroengine ground direct-connected test air heating devices of the prior art adopt electric heating endothermic heaters, as in the d...
