The concept of tapered capillary is introduced as a method of injecting focused plasma jet into the breach of bulk-loaded electrothermal-chemical (ETC) launcher. Tapered capillaries will operate in the confined controlled arc regime, and they can provide the advantage of producing focused hyper plasma jets useful for ignition of ETC systems at controlled(More)
The electrothermal (ET) energetic plasma source (ETEPS) is a different concept in which the ablation mechanism is forced inside of the open-ended capillary that has energetic liner, a propellant. The generation of the ET plasma results from Joule heating and radiant heat transport to the liner. The discharge initiates erosive burn of the propellant, and the(More)
Dual-channel thermal plasma torches can operate with air, argon, or combustible gases to produce high temperature plasma flows. This plasma torch can be used in various important applications such as metal industry recycling, surface coating and hardening, space operations using controlled thrust, and macroparticle acceleration based on the electrothermal(More)
Summary form only given. Current gun technology uses solid propellants that consist of small geometrically similar grains which are ignited by a primer. Propellant burn characteristics are determined by a combination of the chemical propellant itself and grain geometry. The ballistic characteristics of a preformed cartridge cannot be changed in real time.(More)
Summary form only given. The concept of the electrothermal energetic plasma source (ETEPS) involves an energetic gaseous or liquid propellant injection into a confined non-ablative capillary. As the gaseous injection occurs, an arc discharge causes dissociation of the propellant with immediate ionization and combustion. This results in the release of(More)
The electrothermal energetic plasma source (ETEPS) is a new concept in which the ablative mechanism is forced inside of the capillary which has energetic liner, i.e. a chemical propellant. The generation of the electrothermal plasma results from Joule heating and radiant heat transport to the liner. The discharge initiates erosive burn of the propellant and(More)
Tapered capillaries operating in the confined controlled arc regime have the advantage of producing focused hyper plasma jets useful for ignition of electrothermal-chemical ETC systems, at peak kinetic temperatures in the range of 14,000-21,000K (~1.2-1.8eV) and considerable jet pressures of 10-70MPa for input discharge current of 20-30kA over a short pulse(More)
