In the frame of the European Space Agency (ESA) Intermediate eXperimental Vehicle (IXV) project, ESA is coordinating a series of technical assistance activities aimed at verifying and supporting the IXV industrial design and development process. The technical assistance is operated by the Italian Space Agency, by means of the technical support of the Italian Aerospace Research Centre. One of the purposes of the activity is to develop an independent capability for the assessment and verification of the industrial results with respect to the aerothermodynamic characterization of the IXV vehicle. To this aim, CIRA have developed an independent aerothermodynamic database, intended as a tool generating in output the time histories of local quantities for each point of the IXV vehicle surface and for each trajectory, together with an uncertainties model. The whole procedure followed for the definition of the numerical tool and the main results achieved will be presented in this article.

Abstract:In this paper the importance of using accurate CFD simulations in the design of hypersonic vehicles is stressed. The attention is focused on the one hand on the need to providing the vehicle designer with the estimated error bars together with the nominal values of the design parameters. On the other hand it is underlined how, in the different design phases, different levels of accuracy can be used, from simple inviscid computations to complex viscous non-equilibrium modellization, depending on the problem that must be solved. Then, the attention is focused on the kinetic models, from the classic macroscopic to the advanced models based on the state-to-state approach. Some examples of test cases that were used in the last years to validate CFD codes with respect to the kinetic modeling are presented, with the aim of emphasizing the potential advantages in using the state-to-state approach. Finally, preliminary results of the numerical rebuilding of wind tunnel test cases that are currently being performed in the framework of the Phys4Entry Project for code validation are shown.

“…Aerodynamic coefficients in ADB account for several inputs, that is, Mach number, aerodynamic angles, Reynolds number, rotary and unsteady effects along with the action of controls. The ADB is described in detail in (Rufolo et al, 2006). The primary sources of data were represented by the tests carried out at CIRA wind tunnel PT-1 and at the DLR-DNW Transonic Wind tunnel Gottingen (TWG).…”

“…The nonlinear behaviour stems from the effect of Mach number in the transonic regime and from the aerodynamic characteristics of the FTB_1 low aspect ratio, lifting-body configuration. The parameters of the aerodynamic model are firstly determined before flight, fitting a pre-flight aerodynamic database, built upon wind-tunnel test data and computational fluid dynamics analysis (Rufolo et al, 2006). Next, a subset of the model parameters is identified from flight data analysis, in order to update their pre-flight values and to reduce the related uncertainty level.…”
