Radiative heating and erosive burn of a solid propellant subject to electrothermal plasma
- North Carolina State Univ., Raleigh, NC (United States). Dept. of Nuclear Engineering
Electrothermal-chemical (ETC) devices have shown a growing interest for possible various applications that exhibit the generation of high density, high enthalpy flows such as military guns. The interaction of electrothermal plasmas with solid or liquid propellants is not clearly understood. Several experiments have been conducted on specific propellants that show either enhanced burn rates or no effect from plasma impinging on the propellant. The question of whether the externally high heat flux produced from the electrothermal plasma will enhance the propellant burn rate, or the burn rate will be limited by the vapor shield at the combustion flame temperature is still unanswered. Erosive burn experiments conducted on JA-2 solid propellant have shown enhanced burn rates through plasma erosion. This paper explores the erosive burn and radiative heating, their implication on the ETC performance, and whether they re sufficient as augmentation and control mechanisms in electrothermal-chemical devices.
