Three major assemblies make up the two rocket launch target vehicle that will be used at WSMR: 1) 2) 3) an M56A1 solid-fuel rocket motor; a target stage powered by an Orbus-1 motor to accelerate target reentry; and, a conical shaped target containing avionics. The PMB containing the LEAP projectile will be launched from LC 36 into a sub-orbital trajectory by a single launch vehicle. Booster guidance is by an inertial unit. The PMB will separate from the booster after motor burnout and shroud release. The PMB will continue its trajectory past apogee, falling towards a target position. As the PMB acquires and tracks the target, GN 2 ACS, installed in the P.MB, maintains pointiJ;tg at the target. Approximately 151 seconds after the target vehicle is launched from the Sulf Site, the Aries booster carrying the LEAP is launched from LC 36. After reaching apogee, the target's Orbus-1 motor will be fired. Approximately 142.seconds later, the STP will maneuver towards the target's projected flight path for target intercept. As in the single rocket launch experiment, propulsion for the lateral divert maneuver of the LEAP projectile comes from a burn of a small quantity of liquid propellants, (a maximum of 833 grams of N 2 0. and a maximum of 504 grams NJI.). Both target and STP will be destroyed at intercept; however, the PMB and instrumentation will be recovered by parachute. Debris from the launches is projected to fall within the dispersion areas illustrated in Figures 7C and 7D. Two Rocket Launch with PMB and Target in Separate Launch Vehicles - USAKA and Wake Island Two launch vehicles, each launched from a different test site, are involved in this test profile. The LEAP launch vehicles will be lal.mched from facilities at Meek Island in USAKA ·The target vehicles will be launched -from Wake Island, which is about 700 miles ··C ' north of USAKA. Figure 11 shows a tjpical flight profile for this scenario. 1-29
