Intern in Space Transportation Technology Coordination, Super Heavy Reusable Launch System

Our team and mission

The Directorate of Space Transportation (D/STS) mission is the European independent access to and freedom in space. The Directorates main activities are related to the:

• development and exploitation of Ariane and Vega launch systems;
• maintenance and upgrading of the European Space port (CSG) in Kourou French Guiana;
• development of new launch and space transportation systems including reusable demonstrators.

Within the Directorate the Space Transportation Technology Coordination Office (STS-CT) part of the Chief Technical Advisor Office (STS-C) is involved in selected critical preparatory activities with the industry for enabling critical informed decisions by Member States on developing future European transportation capabilities and has the mission of fostering transversal technology synergies across STS and ESA seeking shared and optimized technology roadmaps for Europe.

Field(s) of activity for the internship

Topic of the internship: Super Heavy Reusable Launch System Pathfinder Mission Analysis

In the framework of this internship you will perform analysis cross-checks to support the design optimisation of a two-stage super heavy reusable launch vehicle based on a single engine approach. Therefore your internship will focus on the design optimisation of a two-stage super heavy reusable launch vehicle architecture employing a single engine type for both stages properly clustered for both lower and upper stages. The objective is to investigate the design trade-offs and performance implications induced by the engine commonality with particular attention to trajectory optimisation and vehicle sizing.
More specifically your tasks will include:

• review existing two-stage launch vehicle configurations and engine commonality studies;
• define a reference mission and baseline vehicle parameters (e.g. payload mass target orbit launch site);
• select candidate engines based on performance parameters operational constraints scalability;
• perform mass estimation and structural sizing of the vehicle based on design considerations (similarity engineering estimates etc.);
• perform trajectory simulations for different configurations and staging strategies and relevant trade-offs;
• perform vehicle design verifications based on trajectory results with sensitivity of the launch vehicle performance to key design parameters;
• assess the impact of engine commonality on stage geometry tank sizing and mass ratios providing evidence of advantages and disadvantages of the investigated solutions.
