Popis: | The utility of suborbital launch trajectories to increase the payload capacity for a hypersonic-lifting-body launch vehicle was investigated. This type of trajectory involves deployment of a payload and booster motor from the launch vehicle at suborbital speed. A payload booster motor is required to insert the spacecraft into orbit while the launch vehicle re-enters and returns to earth. For this study, a simplified analytical technique was developed to estimate the payload capacity (not including booster motor) of various suborbital launch trajectories. Comparison with a detailed trajectory simulation showed that the simplified technique provided a reasonable estimate of suborbital trajectory performance. Results indicated that depending on certain vehicle and flight parameters, a hypersonic lifting body following a suborbital ascent trajectory could increase the payload-to-orbit weight by up to 61%. |
