The application of vertical recovery technology to air-launched launch vehicles causes insufficient carrying capacity， and the current launch schemes are not conducive to full utilization of the launch platforms’ performance as a zero-stage reusable power. Given these two problems， the application of reusable technology to and its effect on air-launched launch vehicles are studied from the aspects of the recovery method of the first-stage booster and launch schemes of the launch platforms. Firstly， combined with the force characteristics analysis of the approximate horizontal launch of the air-launched launch vehicles， the design method of the orbital flight program angle and the trajectory optimization methods are derived， the recovery method of the first-stage booster for the reuse of the air rudders is proposed， and the aerodynamic characteristics analysis and guidance control method of the recovery flight section are analyzed. Then， two launch schemes are proposed. One is a combined power high-altitude unmanned aerial vehicle and the other is a reusable unmanned platform propelled by a subsonic aircraft. Finally， the orbit design parameters and the mathematical simulation results of the first-stage booster’s reusable section are presented with a typical air-launched launch vehicle configuration to quantitatively analyze the contribution of the first-stage booster recovery and the two new launch schemes in terms of carrying efficiency into the orbit and economic cost.
