X-38: A Testbed for the CEVCATS-N Code

The paper focuses on today possibility of using a Navier-Stokes code as design/verification tool for the hypersonic regime, on a real engineering environment. Within the frame of Dassault Aviation work for NASA X-38 demonstrator, DLR has performed more than two hundered CFD solutions, Euler and Navier-Stokes, demonstrating that the DLR computer code CEVCATS-N satisfies all criterion to be considered a reliable tool. That is, fulfilling concepts like accuracy, efficiency, flexibility and robustness for a wide spectrum of geometrical shapes and flow conditions.
