Abstract

The invention relates to the technical field of aerospace craft aerodynamic heat ground simulation test devices, in particular to an arc heater rear end cover. The arc heater rear end cover comprises a base body, an auxiliary air channel and a cooling water channel. The base body is of an integrated sheet-shaped disc structure. The auxiliary air channel comprises a plurality of branch air channels, each branch air channel is spirally arranged around the axis, and the branch air channels penetrate through the two end faces of the base body. The cooling water channel is arranged in the base body in a back-to-back disc shape and distributed between the two end faces of the base body. The branch air channels enable cold air injected by the auxiliary air channel to be the same as or similar to the rotating direction of an arc, the auxiliary swirl performance can be improved, the rotating speed of the arc is increased, the residence time of the single-point arc on the inner wall face of an electrode is shortened, and the cooling burden of a heater electrode is relieved. High-pressure cooling water cools the surface of the heated side of the base body through the back-to-back disc-shaped cooling water channel, burning loss of the wall face is reduced, and the cooling performance of the rear end cover is improved.

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 thermal protection method, the selection of heat-resistant materials and their reliability must go through a large number of tests and assessments. The arc heater test period is short and the cost is low. 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 increase the enthalpy and power of arc heater equipment. [0003] To build high-enthalpy and high-power arc heater equipment, it is necessary to comprehensively improve the performance of all parts of the heater, and the cooling performance is the key performance that is the...
