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

This study investigates the interactions between combustor and isolator and the role played
by combustion on choking-induced unstart. Shock train unsteadiness and pressure …

Large-eddy simulations of stable and unstable ramjet operational modes are presented for
an axisymmetric inlet-isolator-combustor configuration experimentally tested in the …

Cavity-enhanced combustion in an optical axisymmetric scramjet with a diverging combustor
is experimentally investigated in Mach 4.5 flows. The axisymmetric scramjet emphasizes …

The combustion characteristics and flame stabilization mechanisms in an axisymmetric
scramjet with a high-enthalpy inflow are investigated numerically in this paper. To consider …

The supersonic wind tunnel facility SBR-50 at the University of Notre Dame was built in 2015
for experimental research related to shock wave (SW) interactions with obstacles and …

The development of well-characterized, reliable, and cost-effective platforms for
experimental aerothermodynamic research is a key factor to advance hypersonic …

Dual-mode operation and mode transition are experimentally investigated in optical
axisymmetric scramjets in Mach 4.5 flows. The axisymmetric scramjet emphasizes generic …

Incipient choking and unstart initiation mechanisms are investigated experimentally in an
ethylene-fueled constant-area direct-connect supersonic combustor with a circular cross …

Vitiation air heater (VAH) combustion characteristics for a direct-connect scramjet combustor
(DCSC) were experimentally studied. The VAH consists of a head, modular chamber, and …
