An original moving mesh CFD technic has been used to compute the flow around a hypersonic vehicle forebody and into its air intake during the engine cowl opening. This technic computes the intersection between a static background (the vehicle forebody) and a moving overlapping mesh (the cowl) at each time step. This ensure a continuity relationship between both meshes and the conservative property of the method. This work is in progress and, so far, only Euler simulations have been conducted. Results show the transient flow during cowl opening. When completely open, the air intake is started
