RLV configurations with partial reusability of 1st or booster stages are in focus of ongoing system studies. Parallel stage arrangement is preferred with a winged stage connected to an expendable upper segment with potentially various internal architectures. The non-symmetrical architecture consists of a winged RLV-stage and attached ELVpart comprising either one or two stages. The selected rocket propulsion is mostly cryogenic LOX-LH2 (gas generator or staged-combustion cycle) but also the two fuel combinations methane and hydrogen are looked at. An engine similar to the European PROMETHEUS is also considered for main stage propulsion and architecture implications are discussed. The paper summarizes major results of the preliminary technical design process. The overall shape and aerodynamic configuration, the propulsion and feed system, the architecture and structural lay-out of the stages are described and different technical solutions are compared. The advanced stage recovery by in-air-capturing is explained and the related European Horizon2020 research project FALCon is introduced.
