This paper describes an experimental investigation of plasma jet properties on PlasmaSonic 350 kW Inductively Coupled Plasma Tekna torch, operated in the Ground Testing Facility System, designed for thermal material protection research and experimental studies of aerodynamics heating effect, under high enthalpy flow testing. The ICPT-350 kW can be operated from 0.3 to 5 bar torch pressure and develops an enthalpy flow conditions up to 31 MJ/Kg. Various experimental measurements such us enthalpy, heat flux and sample surface temperature are presented and discussed. The plasma wind tunnel consists of a stationary test facility in which a high enthalpy flow is generated using plasma generator and a pumping station to reproduce the re-entry conditions of space vehicles. The ground testing facility using Inductively Coupled Plasma Torch 350 kW, (ICPT) are widely used in experimental investigations of heat shield materials and thermal protection systems (TPS) that the external envelop of space shuttle are faced The main purpose of this installation is to reproduce those conditions where material samples are tested under high enthalpy flow such an aerodynamic heating effect under supersonic flow that the capsules may be faced during re-entry to the atmosphere. For this purpose, a complete study and simulation of the physical phenomena, must be studied and completely understood at the ground facility. On this paper we are presenting an experimental measurements of plasma physical parameters compared to the numerical model calculations with a measurement of inner and outer surface temperature of the graphite material sample. The proposed ICPT-350 plasma system will have the ability to perform thermal tests between 10-1000 mbar chamber pressure with 100 % air. Exhaustive instrumentations are also provided with the system allowing characterization of the plasma flow and heat flux on the sample. The performance testing of insulation thermal system such as the improvement of flow characteristics on this plasma tunnel system, passes by a design of high-quality equipment and high control and regulation such as Power supply 7) Advanced control system. 1) Tekna ICP plasma torch 2) Test chamber 3) Supersonic diffuser 4) Vacuum system 5) Heat exchanger 6)
