“…This work proposes an advanced approach to expand the operational domain of the scramjet to o¨design values of Mach number at a ¦xed geometry of the gasdynamic duct. It is based on the experimental results in the ¦eld of so-called ¤Plasma-Assisted Combustion¥ obtained during past years in JIHT RAS [13,15,16]. The following principally important results have been obtained: the bene¦t of plasma generation in the §ow lies not only in heating and active media production, but also in modi¦cation of supersonic §ow structure, including arti¦cial separation, vorticity, etc.…”

The ultimate objective of this work was to enhance the performance of air-breathing engines in transient modes. The paper presents the results of laboratory-scale experiments on ignition of nonpremixed fuel air composition in high-speed §ow by a near-surface electrical discharge. The experiments were ful¦lled under conditions of model supersonic combustor on the plane wall without any mechanical §ame-holder. The ignition and §ameholding of hydrogen air and ethylene air compositions were demonstrated for direct fuel injection into the §ow at low (T 0 = 300 750 K) gas temperature. The deposited power was W pl /H tot < 2% 5% of §ow total enthalpy. The power threshold of fuel ignition over the plane wall was measured by variation of power deposition and fuel mass §ow rate. The combustion completeness was estimated to be reasonably high, η > 0.9, with both hydrogen and ethylene fuels under optimal conditions.
