A light high-temperature-resistant steering engine relates to the field of steering engines and comprises a motor, a speed reducing mechanism, a lead screw assembly, a transmission shaft, a steering engine shell, an angular displacement sensor and a heat absorption armor. The motor, the speed reducing mechanism and the lead screw assembly are connected to the steering engine shell, the transmission shaft is rotationally connected to the steering engine shell, output torque of the motor is output to the lead screw assembly after being decelerated through the speed reducing mechanism, and the lead screw assembly is connected with the transmission shaft. The angular displacement sensor is used for measuring the rotation angle of the transmission shaft; the heat absorption armor wraps the steering engine shell, a cavity filled with a phase change material is formed in the heat absorption armor, a pressure relief hole is formed in the heat absorption armor, and the cavity is communicated with the outside through the pressure relief hole. High-temperature-resistant light materials and a layer-by-layer progressive structural design of heat resistance, heat insulation and heat absorption are adopted, key structural parts of the steering engine are subjected to strong heat insulation, heat conduction and heat radiation are blocked and absorbed layer by layer, and the purposes of being small in size, light in weight (smaller than 3.2 kg, and the power level is 1.2 kW) and resistant to the high temperature of 700 DEG C are achieved.
