Abstract

The development and operation of Reusable Launch Vehicles (RLV) are currently changing the global market of space transportation. A main game changer in this field are the technologies of retro propulsion assisted landing, which is a concept of decelerating the vehicle during its return to ground by firing its engines against the velocity vector. To foster a cost-efficient and sustainable global and European launcher market there is not only an urgent need to build 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. Therefore, in the EU Horizon 2020 project RETALT (RETro propulsion Assisted Landing Technologies), the VTVL approach 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 is performed in the areas of aerodynamics, aerothermodynamics and flight dynamics and GNC, as well as advanced structural parts, materials, health monitoring systems, TPS, mechanisms and 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.
