Off-Nominal Trajectories of SpaceLiner 7-3

Kurzfassung

This simulation study investigates several ascent trajectories of the SpaceLiner Vehicle under off-nominal conditions. In summary the following scenarios have been simulated considering 3 DOF and 6 DOF motion: 1) Nominal undisturbed ascent trajectory 2) Ascent trajectories with atmospheric disturbances a) Large scale wind profile (HWM93) b) Moderate stochastic gusts (Karman) c) Combined disturbances (HWM93 & Karman) 3) Ascent trajectories under anomaly scenarios a) Reduced Isp of the booster’s SLMEs by -3 s b) Premature stage separation by -6.5 s c) Failure of outermost SLME at Lift-Off d) Failure of outermost SLME at Max-Q The results of these simulation cases are analyzed to assess the technical feasibility of the SpcaeLiner concept
