To study the initial status of an air launched rocket prior to launching in air, it is necessary to study the air separation process between the vehicle and aircraft on which the rocket is carried to predetermined launching point. In this paper, a new air departure scheme according to requirements of the launch mission is proposed, and a corresponding dynamical mathematical model based on which the rocket kinetic characters in the vertical plane can be analyzed is set up. The subsequent analysis results indicate that the rocket kinetic parameters after the air separation phase can be up to the mustard of the airborne launch mission.
