Combined aerodynamic and orbital trajectories for partial drag-free flight in super low altitude

This paper reveals the intrinsically linked inter relationship between jumping characteristics of the spacecraft and the lift coefficient when the drag coefficient is very small, based on the quantitative analysis of lift coefficient and drag coefficient on the vehicle orbital leap characteristics. What's more, there demonstrated theoretically the fact that the vehicle can achieve the long-term stable orbital leap when there compensated the air drag via applying the partial drag-free control. Finally, we introduce the attack angle control strategy as the flight strategy to achieve long-term stable jump combining the aerodynamics and orbital dynamics principles.
