Preliminary calculations and writing reports for commercial /scientific missions on Ariane 5 ECA and GS.

Feasibility studies Trajectory / Performance / Visibility / Stages Re-entry with the L/V VEGA :

Update data base for the L/V VEGA (mass budget, propulsion, aerodynamics…). Feasibility calculation and writing reports for program missions VERTA.

Development of a computer code for the Neutral Axis calculation (Z9 Re-entry ) :

Code development (fortran 90) assessing parameters defining the neutral axis used on the 3^rd stage L/V VEGA.

ARIANESPACE (GECI systèmes)

2006 Trajectory and Performance for the Arianespace competing L/V :

Trajectories optimisation and performance calculations on the competing L/V : Atlas, Proton, Delta, Soyuz from CSG.

Taken into account the visibility constraints of the launchers and the re-entry stages.

Trajectory simulation for the Soyuz ST stages in the short distance safety context (DP/SY/IT)

(cross-checking with CNES) :

Definition of the debris cloud with the 6dof (indicated below) and a Monte-Carlo simulation (10000 drawings) from AVD times. Calculation of the deviated trajectories (Dyn.P max. , knocking speed,…).

Dimension / location of the debris cloud and comparison with the toxicity/nuisance limits.

Development of a computer code for L/V flight dynamic simulation (DP/DD/PM) and (DP/SY/IT):

Development (C++) of a simulation code assessing a L/V stage dynamic behaviour during its fallout on the surface (applied on the Soyuz ST stages).

Attitude control (quaternion use) and taken into account of the static and dynamic stability.

2005 Developmentof a simulation code for the re-entry EPC studies (DP/SY/LM) :

(Determination of the impact area size caused by debris from the EPC fragmentation, in order to verify compliance with the requirement of safeguarding the people)

- Validation of the calculation (fortran 90 program) et development of new features.

- Writing technical report.

Setting up of an aerodynamic calculation in the L/V context (DP/DD/PM) :

Analysis of different approaches for preliminary calculation (empirical et analytical).

Aerodynamics of Soyuz ST stages (DP/DD/PM) (cross-checking with CNES) :

Determination of aerodynamic coefficients and definition of the L/V stages static stability for high angles of attack.

Calculation of the damping coefficient during pitch manoeuvre.

INTERNSHIP

CNES (DLA/SDT/EA)

2004 Flight behaviour study of a Japanese RLV (Reusable Launch Vehicle) in transonic phase came within the framework of a collaboration between CNES/JAXA :

Reports of the flight data’s. Exploitation of the recorded values (fortran 90 program + Matlab use) and reconstitution of the flight test.

CFD studies :

Use of elsA code (ONERA) in the case of a Eulerian simulation. Interpretation of aerodynamic coefficients and comparison with the experimental results.

Study of stability and flight performance of vehicle:

Analysis of longitudinal factors and definition of the static stability (calculation of the center of pressure and the static margin) following different configurations

(turning the ailerons and flaps, opening the speedbrakes with different angles of attack)
