Theoretical and experimental investigation of the aerodynamic characteristics of three-dimensional bodies

Three-dimensional aerodynamic shape optimization using genetic evolution and gradient search algorithms

“…The analytic solution to this problem has been previously determined 1 using Newton impact theory assumptions. The expression for the radius as a function of the non-dimensional axial distance (measured from the center of the spherical nose) for the analytically optimal body is given by (28) where r 0 is the specified radius of the spherical nose. r base ' s ^e specified radius of the circular rear plane, and L is the specified total body length from the center of the spherical nose to the rear plane.…”

Numerical and analytical study of transverse supersonic flow over a flat cone

“…Most of this work has dealt with small deviations from axisymmetry, although angles of attack as large as 300 have been studied (Yahalom 1971). Less experimental effort seems to have been devoted to transverse flows (angle of attack equal to 90~ Likewise, theoretical studies by Goman and Davydov (1975) and Gusarov et at. (1979) have concentrated on small deviations from conical shapes in axisymmetric flow.…”
