Overview of Characteristics and Experiments in IPM Plasmatrons
Abstract
Characteristics of IPG series plasmatrons as well as there application for reentry simulation and testing of thermal protection materials are discussed in the presented paper on the basis of 35-years experience of Plasma Laboratory of IPM RAS. Successful application of plasmatrons for simulation of reentry conditions and testing of thermal protection materials is based on using of plasmatron's advantages such as purity of plasma flow, its high stability, excellent reproducibility as well as wide ranges of realized pressure and heat flux. Using of subsonic regimes together with plasmatron's ability for independent smooth regulation of regime parameters such as pressure and power injected in plasma make a plasmatron the most flexible and powerful instrument for simulation of thermochemical action of shock layer on the surface of descent space vehicle, especially when it is necessary to solve problems concerned radiative & convective heating and/or non-equilibrium heat transfer. To the present day long-term aging tests (up to 100 15-minutes testing cycles for one sample) in dissociated gas flow were fulfilled only using plasmatrons. Also there are discussed tests of ablative thermal protection materials, studies of thermo-chemical interaction between dissociated flows and reusable thermal protection materials as well as some %non-space)) applications of plasmatrons as deposition of diamond films and testing of industrial materials on heat shock.
