[Comparaison de méthodes de génération de waveriders derivés d'écoulements coniques]
Les waveriders sont des configurations portantes supersoniques ou hypersoniques qui sont générées à partir d'un écoulement connu empêchant tout déversement latéral de la zone haute pression de l'intrados vers l'extrados assurant ainsi de hautes finesses. Une méthode utilisant un code Euler est utilisée pour étudier des waveriders créés à partir d'écoulements axisymétriques. Dans le cas du cône, les résultats sont comparés avec ceux du système de Taylor–Maccoll et de la théorie des petites perturbations hypersoniques. Dans les conditions de la présente étude à Mach 5 la dernière méthode fournit paradoxalement des résultats comparables à ceux de Taylor–Maccoll aux grands angles de cône (supérieurs à 10°) tandis que la meilleure finesse est obtenue pour de petits angles.
Waveriders are supersonic or hypersonic lifting configurations which are generated from a known flowfield, preventing leakage from the high-pressure undersurface to the uppersurface, and allowing high lift-to-drag ratios. A method based on an Euler code is used to study waveriders generated from the flow field around axisymmetric bodies. In the case of a cone, the results are compared with those given by the Taylor–Maccoll system and inviscid hypersonic small-disturbance theory. In the present study conditions at Mach 5, the last method paradoxically works at high cone angles (greater than 10°) while the best lift-to-drag ratio are obtained with small angles.
