Double Swept Waverider from Osculating-Cone Method
Publication: Journal of Aerospace Engineering
Volume 31, Issue 6
Abstract
Global geometrical relationships are proposed between the design parameters and configuration parameters of the osculating-cone method. A kind of double swept waverider is discussed primarily as an attempt to remedy some of the deficiencies of a traditional waverider. Using nonuniform rational B-spline (NURBS) to represent design curves, the flexibility of the method improves and the smooth surface of the waverider is ensured. Computational fluid dynamics (CFD) analysis is employed to validate the design method and evaluate the advantageous performances of the double swept waverider, such as subsonic characteristics and longitudinal stability. The work provides a novel approach to the aerodynamic shape design for wide-velocity-range hypersonic vehicles.
