Descripción del proyecto
Lograr unos lanzamientos espaciales más eficientes
La carrera por la exploración del espacio y las comunicaciones espaciales ha devenido en misiones con un coste desorbitado, más basura espacial y problemas relacionados con la eliminación segura durante la reentrada. El proyecto ASCenSIon se centra en múltiples cargas útiles en órbita, la reutilización de sistemas de propulsión y la sostenibilidad ecológica y económica. Analizará tecnologías mediante simulaciones y pruebas de funcionamiento para evaluar la durabilidad de los sistemas de propulsión, y desarrollará sistemas para controlar las condiciones de vuelo orbital y de aterrizaje en lanzamientos múltiples. Esto requerirá emplear modelos avanzados de termodinámica y aerodinámica evaluados con técnicas de flujo frío y calor a altas temperaturas, redes de sensores inalámbricos y sistemas fiables de orientación, navegación y control (GNC, por sus siglas en ingles) para garantizar la viabilidad y la aplicación y cambiar el perfil de los lanzamientos espaciales.
Objetivo
The purpose of the ASCenSIon project is to develop a programme that focuses on several specific areas of cutting edge space access research, particularly on launcher systems that are (partially) reusable and capable of injecting multiple payloads into multiple orbits. More than providing design concepts, the network aims to identify and advance critical technologies to prove a feasibility of these concepts. Fields of research and training include propulsion technologies and their reusability; Guidance, Navigation and Control (GNC); aero-thermo-dynamics of re-entry and safe disposal. A variety of technologies will be advanced, including hybrid rocket engines, electric pump feeding and advanced nozzle configurations. Both computational and experimental (cold-flow and hot fire) techniques will ensure an efficient process and reliable results. The reuse of propulsion systems demands an assessment of their durability. It will be conducted by numerical simulations, system analysis with EcosimPro/ESPSS and experimental test runs. The development and integration of wireless sensor networks will allow health monitoring of these critical subsystems. Moreover, novel GNC strategies and processes have to be developed for the whole mission trajectory. This includes solutions for optimised flexibility w.r.t. the orbital insertion conditions as well as dedicated descend trajectories and GNC missionisation for re-entry. The models will cover various recovery concepts and the support of multiple landing sites. This requires an extensive examination of the aero-thermo-dynamics during re-entry as well as of the interactions between stage recovery and propulsion system layout. Ecological and economical sustainability will be addressed as new payload concepts including large constellations increase the demand for safe disposal and space debris mitigation to ensure an open access to space in the future. Furthermore, the utilisation of so called green propellants will be investigated.
