Investigation of characteristic of an arc heater is important to study high temperature performance the reentry problem of hypersonic flight, and disposal of toxic wastes after high temperature burning. The purpose of the present work is to study operating characteristics of a Huels type (49kW) and Hybrid type (24.5kW) are heater including stagnation temperatures of heated gases, and to investigate the range of applicability of characteristic plot proposed by Kindler's relation. These characteristics may be approximated by a power law; V/I=C(I^2/m)^<-α>. These characteristic plots show that regardless the amount of input power and type of hollow electrode are heater, values of α are evaluated approximately as 0.54∿0.61 for Hybrid type, 0.69∿0.74 for Huels type and 0.42∿0.59 for segmented type, while the value of coefficient C differs depending on the type of heater or kind of working gas.
