| 1. | Spacecraft launchers - Ariane 5 and Ariane 6 at the Fauga-Mauzac testing facilities |
| | A first firing was carried out in January 2011, at ONERA Fauga-Mauzac centre, using the 1/35 scale model of an Ariane 5 P230 booster specifically developed to display the phenomenon of shock waves during lift off.... |

| 2. | Einstein and the accelerometer - Zoom in the Lab |
| | The accelerometer is composed of a " test mass ", an object of precisely known mass and form, that is lifted in a ceramic cage by applying electrostatic forces.... By measuring the electrostatic forces necessary to keep it immobile when lifted, the acceleration experienced can be deduced with a precision of a billionth of Earth's gravity, or even better.... |

| 8. | WP4 [ ACT-TILT ] |
| | A tilt-rotor is a unique type of aircraft, which can fly fast and efficiently in forward flight like a turboprop airplane and also takeoff, hover, and land vertically like a conventional helicopter.The tilt-rotor achieves its lift and control in hovering flight in exactly the same way as a helicopter : proprotor system lift, and collective and cyclic pitch control.. |

| | Perturbations at F+=1 resulted in the restoration of conventional low-Reynolds-number lift and aerodynamic efficiency, while excitation-induced lift oscillations were small and hysteresis associated with stall was eliminated.... However, with decreasing Re, larger perturbations (expresses as C) were required to generate useful lift.... |
