title = "Safety issues for a carrier stage of a lifting two-stage space transportation system",
abstract = "Two-stage winged hypersonic flight systems consisting of a carrier stage with airbreathing turbo-/ram-jet engines and a rocket propelled orbital stage represent a promising concept for future space transportation. Among various advantages, they offer an improvement of reliability and safety. Optimal control methods are a means to fully exploit the safety reserves for emergency flight scenarios. Evaluation of the safety improvements concerning the carrier stage is the subject of this paper. The investigation focuses on safe mission aborts to either a specified emergency landing site or to the launch site after an engine failure during cruise flight or an all engine blowout during separation. Basically after an one-engine-out failure, a safe mission termination can be achieved. For an all engine blowout during separation an optimal gliding flight to a specified emergency landing site is considered, with reduced aerodynamic control activity.",
