Abstract

The invention relates to the technical field of aerodynamic thermal ground simulation test devices for aerospace vehicles, in particular to a rear end cover of an arc heater. The rear end cover of the electric arc heater includes a base body, an auxiliary air channel and a cooling water channel. The air channel is arranged through the two end faces of the base body; the cooling water channel is set inside the base body in a coiled shape and distributed between the two end faces of the base body. The branch air channel makes the cold air injected by the auxiliary air channel the same or similar to the rotation direction of the arc, which can improve the auxiliary cyclone performance, enhance the rotation rate of the arc, reduce the residence time of the single-point arc on the inner wall of the electrode, and reduce the cooling burden of the heater electrode . The high-pressure cooling water cools the heated side surface of the substrate through the back-to-back plate-shaped cooling water channel, reducing the burning loss of the wall surface and improving the cooling performance of the rear end cover.

Description

technical field [0001] The invention relates to the technical field of aerodynamic thermal ground simulation test devices for aerospace vehicles, in particular to a rear end cover of an arc heater. Background technique [0002] In the design of various hypersonic vehicles, the selection of thermal protection methods, thermal protection materials and their reliability must undergo a large number of tests and assessments. The arc heater has a short test period and low cost. It is the core test equipment for researching the thermal protection technology of aerospace hypersonic vehicles at home and abroad. With the iterative update of my country's hypersonic aircraft models, there is an urgent need to improve the enthalpy and power of arc heater equipment. [0003] To build a high-enthalpy and high-power arc heater equipment, it is necessary to comprehensively improve the performance of each component of the heater, and the cooling performance is the key performance to be consi...
