Wind tunnel tests of configurations designed on the basis of these principles with a volume coefficient typical for vehicles operating on a cryogenic fuel are performed at Mach numbers M = 7−10 and Reynolds numbers of the order of several million and provide the maximum lift-to-drag ratio (L/D)max = 5.7−5.6, which is 10−30% higher than that of currently available aerodynamic configurations. In contrast to known configurations, the lift-to-drag ratio of the new configurations does not decrease with increasing Mach number. At M > 7 and full-scale Reynolds numbers, the lift-to-drag ratio of such configurations in cruising flight can reach (L/D)max ≈ 7. The aerodynamic characteristics of the proposed configurations at low and moderate supersonic speeds are similar to those of typical combinations of a body with a low-aspect-ratio wing.
