Abstract

The invention provides an electronic control heat shield which comprises position sensors, a motor, a screw rod, a multi-layer fixed rod, a guide rail, a driving nut and signal induction devices, wherein the two ends of the multi-layer fixed rod are connected with the guide rail, the screw rod is connected with the multi-layer fixed rod through the driving nut, and the motor drives the screw rod to rotate so as to drive the multi-layer fixed rod to move along the guide rail. A plurality of position sensors are arranged on the guide rail, and the signal induction devices are arranged at the two ends of the multi-layer fixed rod and used for sensing signals of the position sensors. The signals of the position sensors are utilized to control the opening and closing area of the heat shield, and the opening and closing area is easy to control; motor steering and step numbers can be controlled on the ground through a numerical control computer to achieve the opening and closing work of the heat shield, and the on-track controlling reliability of the heat shield is improved.

Description

technical field [0001] The invention relates to an electronically controlled heat shield, in particular to an on-rail control method for an electrically controlled heat shield. Background technique [0002] Electric control heat shield is a new type of active thermal control device for spacecraft, generally composed of drive components (stepper motor and reducer), transmission components (nuts and screw rods, etc.), protective cover, multi-layer heat insulation components (heat insulation It is composed of foldable multi-layer screen, ring buckle, etc.), position sensor, structural parts and other components. According to the requirements, the electric control heat shield can be driven by the stepping motor and reducer to rotate the screw, and the screw is converted into translation through the rotation of the nut, pushing the multi-layer fixed rod and the multi-layer opening and closing movement of the heat shield to block or expose the stars The heat dissipation surface, ...
