ORAGES: A Micro-Satellite to Detect and to Locate the Lightning VHF Emissions From Space

Space based sensors enable continuous observations of the convective activity over the whole earth. The ORAGES mission is designed to locate and detect the VHF emissions of lightning from space with a storm scale resolution. The altitude of the orbit will be at 700-800 km with an inclination of 20-25°...

Noise Sources Prediction in a Slat Cove by Mean of a Hybrid Zonal RANS/LES Approach

This paper describes some significant steps towards the numerical simulation of the noise radiated by the high-lift devices of a plane. A hybrid RANS/LES strategy is proposed to reduce the cost of an accurate numerical prediction of the unsteady noise sources in such configurations. This method allows considering some reduced...

A Model Deformation Method Applied to PSP Measurements

This paper describes the new method which has been developed to correct the effects of model deformation on PSP images. This method is based upon grid tracking instead of marker tracking. The grid is stretched according to a deformation law and deformation parameters. The deformation law is designed by using...

Research Ramjet Program: An Initiative to Improve Knowledge on Ramjet Reactive Flowfields

A research ramjet program has been initiated at ONERA with the support of DGA/SPNuc in 1995 with the aim to improve methodology for ramjet combustion chamber design and tuning by using validated CFD codes. The approach used was to design and manufacture a specific ramjet model in order to setup...
