本文介绍了将人员和货物安全送入低地球轨道的一种新的空中发射方法的研制和飞行试验。一种新的火箭也正在设计中，将由一架改装的747客机携带并使用新的空中发射方法发射。这种新的空中发射方法，称为短索空投（t/LAD）发射，将大大提高人员进入低地球轨道的简单性、安全性、成本和可靠性。t/LAD发射不需要运载火箭上的机翼或尾翼;大大降低了上升动压、侧向加速度和弯曲力，以及火箭发动机推力矢量控制;并允许运载火箭使用简单且非常安全的蒸汽增压（Vapak）发动机循环。本文报道了用t/LAD发射方法投放三个23%比例跌落试验件的飞行试验结果。
This paper describes the development and flight testing of a new air-launch method for safely launching personnel and cargo into low Earth orbit (LEO). A new rocket is also being designed that will be carried by and launched using the new air-launch method from a modified 747 airliner. This new air-launch method, called trapeze-lanyard air drop (t/LAD) launch, will greatly improve simplicity, safety, cost, and reliability of launching personnel into LEO. A t/LAD launch eliminates the need for wings or fins on the launch vehicle; greatly reduces ascent dynamic pressure, sideways accelerations and bending forces, and rocket engine thrust vectoring control; and allows the use of a simple and very safe vapor pressurization (Vapak) engine cycle for the launch vehicle. This paper reports on the flight-test results of dropping three 23%-scale drop test articles using the t/LAD launch method.
