摘要	Blowout limits of supercritical kerosene were experimentally studied using direct-connect supersonic model combustors at various air and fuel conditions. Effect of air stagnation temperature on the blowout limit of supercritical kerosene injected from the wall upstream of a cavity was firstly examined in Mach 2.5 airflows. Blowout limit of supercritical kerosene injected from another location, the rear part of the cavity bottom, was also investigated in Mach 2.5 airflows to study the influence of fuel injection locations. Since results demonstrate the injection from the wall upstream of the cavity is beneficial to a wider stable combustion range, the blowout limits of supercritical kerosene injected from the wall upstream of the cavity were furthermore investigated in Mach 3.0 airflows. Moreover, with fuel injected from the wall upstream of the cavity, effects of stagnation pressure on the lean-fuel blowout limit were investigated in wide stagnation pressure ranges at three air stagnation temperatures. Finally, effect of the diverging angle of the combustor on the lean-fuel blowout limit was studied.
