The invention discloses a super-high-
enthalpy arc heater
anode. With the super-high-
enthalpy arc heater
anode adopted, a situation that arc heaters in the prior art cannot be used for simulating environments with super-high-
enthalpy values can be avoided. The arc heater
anode includes a plurality of anode terminals, an insulating ring, a cavity and a plurality of resistors; the plurality of anode terminals are fixed onto the insulating ring in a manner that the plurality of anode terminals do not contact with each other, so that the plurality of anode terminals can be mutually insulated; the cavity is taper-shaped; one large-inner
diameter end of the cavity is fixedly connected with the insulating ring; the direction of an
electric arc changes when the
electric arc passes through the cavity the inner
diameter value of which is gradually increased, and therefore, a resulting magnetic force makes plasmas flow to and concentrate at a center region of the cavity, and accelerate; one end of each
resistor is electrically connected with an anode terminal, and the other end of the corresponding
resistor is electrically connected with the positive pole of a power source; the root of the
electric arc can be uniformly divided into a plurality of root units through adjusting the resistance values of the resistors, and the plurality of root units are attached to the plurality of anode terminals, and therefore, a uniform flow field can be generated. The super-high-enthalpy arc heater anode of the invention can be applied to
simulation high-altitude thermal environments in which
aerospace crafts returning from
deep space exploration.
