Internal Research Fellow (Postdoc) in Spacecraft "Design for Demise"

This post is classified F2.

Location
ESTEC, Noordwijk, The Netherlands  

Description

The Propulsion and Aerothermodynamics Division (TEC-MP) is responsible for:

  • support to projects and definition/execution of technology programmes in the areas of chemical propulsion (systems utilising liquid, solid, hybrid and gaseous propellants for spacecraft and launch vehicles), electric propulsion (electrostatic, electromagnetic, and electrothermal systems), advanced new propulsion systems (e.g. air-breathing engines for advanced launch vehicles and applications of nuclear propulsion to space missions), external and internal aerothermodynamics of relevance to propulsion systems, ascent, cruise and re-entry of space vehicles through the Earth's or planetary atmospheres;
  • architecture and technology assessment of new space transportation vehicles for Earth orbit, exploration and orbital systems applications;
  • development of components for propulsion systems (valves, regulators, tanks, GSE, etc.);
  • development of propulsion and aerothermodynamics simulation tools and support to the evolution of the related European test facilities.

The Flight Vehicles and Aerothermodynamics Engineering Section (TEC-MPA) is responsible for:

  • flight vehicle engineering;
  • computational fluid dynamics;
  • ground testing, and ground-to-flight transposition methods for internal and external flows;
  • external and internal aerothermodynamics of relevance to propulsion systems;
  • ascent, cruise and re-entry of space vehicles through the Earth's or planetary atmospheres;
  • plume analysis;
  • multi-physics modelling;
  • fluid-structure interaction phenomena;
  • exploitation of flight data from flight experiments, especially involving aerothermodynamics and (re-)entry.

Field of activities/research

Spacecraft “Design for Demise” or D4D is currently the solution proposed at system design level to ensure compliance with the risk requirement where there is uncontrolled Earth entry from space. To minimise risk to the human population, the requirement for spacecraft re-entry is a casualty risk below 10-4. Compliance can be achieved by performing controlled de-orbit, but the mass and cost impact can be high. An alternative is to ensure passive, safe re-entry within a 25-year timeframe using D4D techniques and technologies.

The proposed programme of work is for 12 months and has the following objectives:

  • Objective 1: Survey the current state of the art of Design for Demise as applied to non-space industrial processes (buildings, transportation, manufacturing) as well as space missions. The related fields of research should include aerodynamics, thermodynamics, propulsion, structures and materials. The research will comprise a survey of the non-space sector versus space mission design. For the space part, special attention should be paid to the technology activities already initiated in TEC in the D4D area and ESA mission needs.
  • Objective 2: Based on ESA mission needs, investigate and assess new, efficient, and cost-effective D4D methods involving innovative materials, structures and aerodynamic shapes. This objective will take into account the upcoming new complex ESA missions when uncontrolled re-entry may be required. This objective will also cover the investigation and benchmarking of demisability problems and solutions.
  • Objective 3: Design, develop and run a series of simulations for ESA missions where demisability will be used to safely re-enter a spacecraft, launch stage, or dead satellite. Development of the simulations will be performed using the existing TEC tools and incorporating the required new techniques and technologies such as to maximise efficiency and minimise running time.
  • Objective 4: Propose a comprehensive plan to test, verify, and validate the simulations developed using the ESTEC Testing Facilities and laboratories.
