- Abstract
In January 2004, the project of China’s lunar exploration was approved to set up, opening the curtain of China’s deep space exploration. Exploring the Moon is a milestone of China space cause following artificial satellites and manned spaceflight. Chang’e Project comprises three development phases: orbiting about, landing on and returning from the Moon. The first phase of the project is to launch a lunar orbiter (Chang’e 1) round the Moon to carry out lunar exploration, and will be launched in 2007. “Chang’e 1” will operate in a lunar polar orbit with inclination of 90 degrees to lunar equatorial plane. It will adopt a circular lunar polar orbit to acquire the remote sensing images with the same resolution along the whole orbit, and choose an orbit with a lower altitude of 200 km in order to increase the resolution of images. Chang’e 1 orbiter will be built, based on the DFH-3 Comsat platform, by fully inheriting the mature technologies and products of Ziyuan satellite and conducting adaptability reform. According to the characteristics of the Moon and the lunar scientific exploration mission, in comparison with DFH-3 satellites, the lunar orbiter has its unique characters in thermal control subsystems. The complicated flight process, multifold spacecraft flight attitude, especially the specific temperature distributing on the moon surface, all that make the satellite surface thermal flux vary acutely and give great difficulty to thermal design. In the paper, Chang’e 1 satellite is described briefly and the thermal control characteristic is analyzed especially. Then the thermal control system for Chang’e 1 is described, and the thermal model and the numerical results are analyzed. The results indicate that the thermal control design can keep the equipment within the desire temperature range.
