摘要

Fully Reusable Two-Stage-To-Orbit concepts (FRLV TSTO) are one of the potential solutions for meeting economical and technical objectives of the second generation RLV while lowering the technological demand. In 2001, CNES initiated system studies (SYST-RLV) aiming at defining the most promising FRLV TSTO configurations in terms of technical and technological challenges as well as economical effectiveness. For such purpose EADS Space Transportation (EADS-ST) has led and is leading an industrial team involving French companies and organizations such as Snecma Moteurs, Dassault Aviation and Onera. The first phase, SYST-RLV Ⅰ, was devoted to identifying the most promising configurations through systematic computation of launcher staging and assessment of stage main characteristics as a function of staging velocity. The second phase, SYST-RLV Ⅱ, produced a preliminary system design of a selected configuration EVEREST, addressing all the tasks required for the feasibility assessment: show stopper identifications, assessment of key elements such as mass budget, and programmatics and costs. The resulting EVEREST configuration is presented. After the previous presentation in Bremen (IAC-03-V.4.05), this paper presents the current status, as phase Ⅲ is underway. In this third part, a more in-depth analysis is being performed on the most critical EVEREST features, in order to confirm their feasibility: 1. Launcher thermal-functional parameter evolution during the mission 2. Wing-fuselage integration 3. Stages thermal-mechanical architecture 4. Cost and operations consolidation.
