Abstract: Investigation of characteristic performance of a high enthalpy flow is important for designing the reentry problem of hypersonic flight vehicle and disposal of waste. A high enthalpy wind tunnel, with Huels type DC-arc heater, is improved to 54kVA(49kW) input power source and its characteristics are investigated. In the case of arc heated flow, the mass flow rate m, the stagnation pressure po, the discharge current I and the voltage V are measured by experimentally by comparing these results of 27kVA(24.5kW) input power in this arc heater. The stagnation temperature To was not measured, however a method of estimating it from m and po with the aid of the high temperature air tables, is proposed by assuming isentropic flow. In the present experiments, the average value of stagnation temperature are evaluated about 2000K ~ 2500K. K.Kindler's graph, for the electric resistance V/I versus the similarity parameter I^2/m are plotted from the present data for air, in addition another data of Huels, Hybrid and segmented type arc heaters are compared to the present data.
