Abstract
This study presents the results of an experimental investigation of self-ignition of liquid fuels sprayed into a supersonic high enthalpy air flow. The experiments were performed with an IT-301 supersonic impulse tube using a model in the form of a plate (190 X 90 mm). Uses a liquid of complex bororganic composition (liquid 1). Finds that in the experiments with liquid 1 the difference between extinction and self-ignition temperatures found in gaseous hydrogen experiments is absent. Indicates that the combustion termination range for liquid 1 is also its self-ignition range in a supersonic air flow for normal injection. Notes that with decrease in temperature the difference between the delay times of hydrogen and liquid 1 decreases.
