| 1. | Aeroacoustics - Reconciliation of calculation time and complexity - Onera |
| | View of the different grids and calculation of the interference field caused by two turboreactor air intakes... |
| |
| 2. | Applied Aerodynamics - ONERA / DAAP |
| | Although these avenues of research are principally applied to the external aerodynamics of aircraft, missiles, launchers and helicopters and to aerobic propulsion units (turbomachines, air intakes), they also concern land based vehicles, surface vessels and submarines.... |

| 3. | Air streams on the water - - Navy ships ' aerology - Zoom in the Lab |
| | Then, the areas without plumes can be chosen for the crew's fresh air intake.... |

| 4. | Aircraft and Helicopter Icing - ONERA / DMPH-EN |
| | Ice shape deposit obtained in a wind tunnel on a leading edge of a wingWhen a plane flies through a supercooled1 droplets cloud, ice accretion occurs on the front parts of structure (wings, tail plane, air intakes).. The ice deposit can cause, on the one hand, very important aerodynamic airfoil degradations, on the other hand, engines extinction due to ice ingestion coming from air intakes.. |

| 5. | Numerical Aero-Acoustics of Fans - ONERA / DSNA-EN |
| | The convection effects due to the flow heterogeneity, and the acoustic transmission by the air intake and the exhaust are thus within the scope of current simulations.... |
| |
| 6. | Plasma Control for Electromagnetism Project - Onera |
| | For the second application, protection of air intakes is preferred, by creating a discharge inside the duct.... |

| 7. | Two-component plane PIV at ONERA DAFE - ONERA / DAFE-EN |
| | Shock-induced separation is a frequently encountered phenomenon in external and internal transonic flows, which may cause detrimental unsteadiness and dramatically reduce the aerodynamical performances of, e.g., an airfoil or an air intake.... |
| |
| 8. | Aircraft and Helicopter Icing - Experimentation and Simulations - ONERA / DMPH-EN |
| | Existing codes will also be adapted to different parts of a plane (air intake, guide vanes...).... |
| |
| 9. | Transatmospheric Aircraft (AHYP1) |
| | Like a ramjet, it compresses the air simply by slowing it down in the air intake, but the speed remains supersonic at the combustor inlet and throughout the engine, which is why this type of engine is called scramjet (for supersonic combustion ramjet).... |
| |
| 10. | Subsonic Aircraft (ASUBg) |
| | When an aircraft flies through a supercooled droplets cloud, ice accretion occurs on the front parts of structure, (i.e. wing, tail plane, air intake), what can conduct to fatal accidents.... |
