DESCRIPTION:Online Seminar on Aerothermal analysis of a vertical landing re
 usable launcher configuration by means of CFD

 Abstract:  The European space strategy aims at 
 maintaining autonomous\, reliable and cost-effective access to space. Reus
 ability represents a possible approach for reducing costs and improving fl
 exibility of European launch systems. Many projects aim to develop cutting
 -edge technologies for Vertical Take-off Vertical Landing (VTVL) Reusable 
 Launch Vehicles (RLVs) which return to and land to Earth applying retro pr
 opulsion combined with Aerodynamic Control Surfaces (ACS)\, i.e. RETALT (H
 orizon 2020)\, RETPRO (ESA)\, and concepts for next-generation launch vehi
 cles: CALLISTO (DLR-CNES-JAXA)\, THEMIS (ESA – large European consortium
  led by Ariane Group).In the presentation\, a reference Two Stage To Orbit
  (TSTO) RLV configuration\, named RETALT1\, developed in the framework of 
 RETALT project\, with a design similar to the SpaceX rocket ”Falcon 9”
 \, is used to discuss aerothermodynamic challenges introduced by this new 
 category of launchers.The assessment of thermal loads\, during the entire 
 trajectory\, is essential for the correct dimensioning of the thermal prot
 ection system and for sizing other important structural parts like aerodyn
 amic control surfaces and landing legs. Due to the costs and limitations o
 f ground-based testing for large scale vehicles these predictions rely int
 ensively on numerical simulations (CFD). The need of aero-thermal database
 s\, as a fast-response surrogate model for the aerothermodynamic heating\,
  arises because of the practical impossibility of performing unsteady CFD 
 analysis over the entire trajectory due to the large disparity of fluid me
 chanical and structural time scales. The construction of these databases i
 s based on a representative set of CFD simulations which cover at least th
 e flight regimes with significant thermal loads. An analysis of representa
 tive CFD results is provided with the aim to show typical flow field pheno
 mena and the resulting heating patterns occurring during the ascent flight
  and the atmospheric entry of RETALT1 vehicle.
 Biography:  Mariasole Lau
 reti obtained the MSc and PhD at the Department of Aerospace and Mechanica
 l Engineering at Sapienza University of Rome\, working on the modelling an
 d simulation of aero-acoustic phenomena in large aft-finocyl solid rocket 
 motors.She is currently employed at DLR – Institute of Aerodynamics and 
 Flow Technology in Göttingen as aerothermodynamics engineer. Her main tas
 k is the assessment of aerodynamic properties and thermal loads occurring 
 on reusable launch vehicles during the entire flight trajectory. She is al
 so involved in project related to plasma-radar interaction and space debri
 s.
