| Abstract: | A quick algorithm for designing emergency orbital transfer scheme that can meet the requirements of measure,fuel and time during emergency orbital transfer was presented.The orbital transfer mode suitable for variable search was given.The question of designing orbital transfer scheme quickly was transformed into the question of restricted optimization.And the entire mathematics model of measure restrictions was established and the corresponding algorithm for measure restrictions was presented.Orbital transfer scheme,that is required not only to meet measure restrictions,but also to achieve optimal goal,was found by using genetic algorithm.Cases of calculation show that the orbital transfer schemes designed by using this quick algorithm can meet the need of emergency orbital transfer mission. |
