The invention belongs to the technical field of high-speed aircraft structure thermal tests, and particularly relates to a high-speed aircraft structure thermal test heating system which comprises a quartz lamp tube, a silicon controlled rectifier, a controller, a first thermocouple and a second thermocouple. A plurality of quartz lamp tubes are arranged side by side and are arranged close to the test piece; the first thermocouple is arranged on the test piece; the second thermocouple is suspended between the quartz lamp tube and the test piece; the thyristor is connected with the quartz lamp tube; the controller is connected with the first thermocouple, the second thermocouple and the quartz lamp tube; the controller, the first thermocouple and the quartz lamp tube form outer ring indirect negative feedback control for controlling the temperature of the test piece; the controller, the second thermocouple and the quartz lamp tube form inner ring direct negative feedback control for controlling the temperature of a suspension point; the outer loop indirect negative feedback control takes the target temperature of the test piece as a control target value, and the inner loop direct negative feedback control takes the output value of the outer loop indirect negative feedback control as a control target value.
