A Global Approach to Near-Earth Object Impact Threat Mitigation (NEOSHIELD)
Date du début: 1 janv. 2012, Date de fin: 31 mai 2015,
Collisions of asteroids and comets with the Earth have taken place frequently over geological history and have altered the evolutionary course of life; there is no reason why they should not continue to hit the Earth at irregular and unpredictable intervals in the future. Thousands of near-Earth objects (NEOs), mainly asteroids, have been discovered over the past 20 years and the reality of the im ...

Characterization of Wall Temperature Effect during Transition of Hypersonic flow over a Cone By Experiments And Numerical Simulations (TransHyBeriAN)
Date du début: 1 juin 2011, Date de fin: 31 mai 2013,
The development of secure and re-usable re-entry vehicle requires the complete control of the heat distribution on its Thermal Protection System (TPS).During the most critical re-entry phase, the hypersonic flow along the vehicle initiates a laminar boundary layer inside of which most of the transfer phenomena take place (heat, momentum and mass transfer). If at one position of the vehicle, this b ...

Technologies for Safe and Controlled Martian Entry (SACOMAR)
Date du début: 1 janv. 2011, Date de fin: 30 juin 2012,
"The main objective of the study is the experimental and numerical study of gas surface interaction phenomena in the high enthalpy flow field behind the bow shock in front of a model at Martian entry flow conditions. The improvement of physical modelling using experimental data and its implementation into the CFD codes is essential to understand and interpret the physical processes. At the end the ...
