Study On The Scheme Of Manned Lunar-landing Mission Supported By Space Station

Based on the three steps of Chinese manned spaceflight, the main work of this dissertation is to study the scheme of manned lunar-landing mission supported by space station and to solve some crucial problems in the scheme. The main achievements obtained in this dissertation are as follows:1. The overall scheme of manned lunar-landing mission supported by space station is researched. The key issues to be solved in the scheme are given concretely. The scale of space station for manned lunar-landing mission is conceived.2. A trans-lunar trajectory model is established, and the constraint conditions are given according to practical situations in engineering. The parameters of trans-lunar trajectory are calculated using numerical method, and the location of entrance point and the appropriate launch window are analyzed. And then, using STK software, a method for revision of the results in primary design is given, and the high precision trans-lunar trajectory is gained.3. By analyzing the constraint conditions, the calculating method for launch window is brought out. Then the launch window in rendezvous between aerocraft and space station is researched.4. The fuel consumption model is established based on the characters in various phases of the lunar-landing mission. Fuel consumption in each phase is studied. And the total mass of aerocraft in LEO is calculated.The research in the paper indicates that the mode of manned lunar-landing mission supported by space station has well reusability and inheritability, and an idea for the scheme of lunar-landing mission is provided for our country.
