A review of fundamental research in combustion stabilization for hypersonic airbreathing
propulsion is presented. Combustion in high-speed airbreathing propulsion systems …

Recesses in the walls of supersonic combustion chambers–cavities–have emerged as a
preferred flameholding device since they are non-intrusive, hence resulting in reduced drag …

The frontier in hypersonic flights via an air-breathing scramjet faces a formidable challenge,
because the operational principle is built on thermal compression, which is inherently …

Cavities are widely used as flameholders in supersonic combustors due to their outstanding
potential to stabilize combustion without excessive total pressure loss. A review of cavity …

Dual-mode scramjets have the potential to provide efficient, air-breathing propulsion at high
flight Mach numbers. Flame stabilization and spreading are a challenge in such engines …

The present work describes the numerical investigation on the implication of the geometrical
configuration of a cavity with a strut-based scramjet combustor. Firstly, the combustion …

Abstract A Quasi-DC (Q-DC) electrical discharge generates a highly transient filamentary
plasma in high-speed airflow. Major specific properties of this type of discharge are realized …

This paper considers the modes of plasma-stabilized supersonic combustion in a cavity-
based flameholding configuration. The testing was performed in the SBR-50 supersonic …

The cavity flameholder has been widely used in scramjets to improve mixing and
combustion rates. While many have investigated modifications to the cavity downstream …

The Hypersonic International Flight Research Experimentation (HIFiRE) program is a
collaborative international effort designed to study basic hypersonic phenomena through …
