abstract = {The development and operation of Reusable Launch Vehicles(RLV) arecurrently changing the global market of space transportation. A main game changer in this field are the technologies of retro propulsion assisted landing, whichis a concept of decelerating the vehicleduringits return to groundby firing its engines against the velocity vector.To foster a cost-efficient and sustainableglobaland Europeanlauncher market there is not only an urgent need to buildup the necessary know-how on state-of-the-art Vertical Take-off Vertical Landing (VTVL) Two Stage To Orbit (TSTO) concepts, but also to go beyond this approach. Historically, many concepts of Reusable Launch Vehicle (RLV) are based on Single Stage To Orbit (SSTO) designs. Therefore, in the EU Horizon 2020 project RETALT (RETro propulsion Assisted Landing Technologies),the VTVLapproach is investigated in a twofold manner:A configuration similar to the SpaceX rocket “Falcon 9” serves as a reference for the state-of-the-art TSTO RLV.A configuration similar to the DC-X serves as a reference for a VTVL SSTO.In this way, the concept of vertical landing with retro propulsion is investigated in a more general way and has the potential to be applied to more concepts of future RLV.In the RETALT project research for both reference configurations isperformed in the areas of aerodynamics, aerothermodynamics and flight dynamics and GNC,as well as advanced structural parts, materials,health monitoring systems, TPS, mechanismsand advanced propulsion assisted landing systems.This paper gives an overall overview of the project; the current status of the project will be presented and an outlook of future activities will be given. Furthermore, the configuration layout and landing concept of both configurations will be discussed in more detail. Advanced structures and mechanisms of RETALT configurations are discussed in a complementary paper.},

abstract = {To foster the competitiveness of the European industry on the global launcher market there is not only an urgent need of building up the necessary know-how on state-of-the-art Vertical Take-Off Vertical Landing (VTVL) Two Stage To Orbit(TSTO) concepts, but also to go beyond this approach. Historically, many concepts of Reusable Launch Vehicle (RLV) are based on Single Stage To Orbit (SSTO) designs, e.g. the VentureStar, the DC-X and the Russian CORONA. In the EU Horizon 2020 project RETALT (RETro propulsion Assisted Landing Technologies) the VTVL approach is also investigated for SSTO RLV. In this way, the concept of vertical landing with retro propulsion is investigated in a more general way and has the potential to be applied to more concepts of future RLV.The vertical landing of an RLV applying retro propulsion is a complex multidisciplinary task. The investigation for both reference configurations will be performed in the areas of aerodynamics, aerothermodynamics and flight dynamics and GNC as well as advanced structural parts and materials, health monitoring systems and advanced propulsion assisted landing systems. The focus of the contribution of MT Aerospace lies on design and manufacturing of hardware for aerodynamic and aerothermal experiments as well as demonstrators of structures and mechanisms of aerodynamic control surfaces and landing structures. Therefore, TRL 5 will be reached during the project. This paper presents an outlook on the upcoming activities.},
