Abstract: A jet screen ignition scheme has been developed based on the investigation of the ignition environment of the burning zone in the high speed flow combustor.It features a short time change of the flow pattern in the high speed flow near the wall during the ignition period,which is caused by a thin and bend high speed gas jet.A specially designed ignition experiment on a model of an aerogasturbine combustor verified success of the proposed scheme and showed its potentiality in enlarging the ignition range of the high speed flow combustor.
