International audience; Dual-mode ramjet propulsion systems are suggested for the next generation high-speed flight vehicles. Here, we combine experimental measurements of high-speed (subsonic and supersonic) combustion at different operating conditions in the LAPCAT-II dual-mode ramjet combustor with Large Eddy Simulations (LES) using finite rate chemistry models and new skeletal H2-air combustion chemistry. The LAPCAT II combustor consists of four sections, and experiments have been performed for wall injection of H2 in a Ma 2.0 vitiated air-flow for total pressures and temperatures of p0=0.40 MPa, 1414 K
