- Abstract
This paper deals with the aerodynamic performance analysis at hypersonic speed of an unmanned aerial vehicle suitable for research activities in re-entry flight technologies. The concept under investigation belongs to the winged vehicle configurations, and features a rather blunt body architecture. Both engineering-based and computational fluid dynamics methods have been considered to assess vehicle aerodynamics in the framework of a conceptual design phase. Indeed, perfect gas and thermo-chemical non-equilibrium computational fluid dynamics simulations, with the air modeled as a mixture of five or more (up to eleven) species, are carried out at several flow conditions compatible with a typical re-entry trajectory, according to the space-based design approach. The range between Mach 2 and Mach 25 was analyzed. A summary review of the concept aerodynamic characteristics, including longitudinal and lateral-directional stability, is performed and reported in the paper.
