Abstract�� A quick algorithm for designing emergency orbital transfer scheme that can meet the requirements of measure, fuel and time during emergency orbita l transfer was presented. The orbital transfer mode suitable for variable search was given. The question of designing orbital transfer scheme quickly was transf ormed into the question of restricted optimization. And the entire mathematics m odel of measure restrictions was established and the corresponding algorithm for measure restrictions was presented. Orbital transfer scheme, that is required n ot only to meet measure restrictions, but also to achieve optimal goal, was foun d by using genetic algorithm. Cases of calculation show that the orbital transfe r schemes designed by using this quick algorithm can meet the need of emergency orbital transfer mission.
