Problems solved by technology
[0006] In view of the simulated heating scheme in the prior art, it is difficult to control the constant temperature condition of the heat exchange process during the pipeline transportation process of injection to the combustion chamber. The heating oil is far from the fuel injection port of the combustion chamber, and the temperature distribution during the heating process is uneven. And it is impossible to simulate the heat transfer process of the actual combustion chamber heat exchange channel, which affects the technical problems of kerosene flow heat exchange and the accuracy of heating and cracking component data. The present invention provides a heat flow environment that can simulate the surface of the engine heat exchange channel. Core body and heating equipment for simulated heating of kerosene with increased heat transfer area, thereby effectively improving the accuracy of test data

The present invention provides a core for simulated heating of kerosene, which includes a body and a channel, the body is used to heat the medium by self-heating; the channel is from the side surface of the body to the The central direction of the main body is recessed, and the channel runs through the main body along the axial direction of the main body, and the channel is used for the circulation of the medium. At the same time, the present invention also provides a heating device, which includes the core for simulating heating for kerosene and a driving coil for driving the core to generate heat. Compared with related technologies, the core body and heating equipment for simulated heating of kerosene provided by the present invention can simulate the heat flow environment on the surface of the engine heat exchange channel, increase the heat exchange area, and thus effectively improve the accuracy of test data.
Description
technical field [0001] The invention relates to the technical field of aerospace ground test simulation equipment, in particular to a heating equipment. Background technique [0002] The development of hypersonic vehicles is a hot spot in the development of the aerospace field today, and has attracted great attention from Europe, America, Russia and other countries. Because the high speed of the airflow in hypersonic flight will bring significant aerodynamic and thermal loads to the aircraft structure (especially the combustion chamber), the temperature of the uncooled combustion chamber can be as high as 3000K, which completely exceeds the bearing capacity of the existing structural materials, so The key to designing a hypersonic vehicle is to solve the problem of thermal protection and thermal management of the vehicle. Endothermic hydrocarbon fuels (mainly kerosene) are selected as regenerative coolants for scramjet engines due to their excellent performance, wide range ...
