Aerodynamic Forces On Noncircular Cross-section Missile Forebodies
Abstract
A numerical investigation is performed to develop the aerodynamic characteristics of forebodies with noncircular cross sections in supersonic cruise. A robust, second order accurate Euler code, is utilized to determine CL, CD, and CM for forebodies with circular, square, diamond, triangle, and inverted triangle cross sections. The predictions at Mach 2.01 compare well with wind tunnel data for angles of attack from 0 to 6 deg. Computed results at Mach 3.0 show that distinct aerodynamic advantages may be obtained by using forebodies with noncircular cross sections. In supersonic cruise, forebodies with noncircular cross sections develop considerably greater lift and lift/drag ratios than forebodies with circular cross sections. © 1991 by the American Institute of Aeronautics and Astronautics, Inc.
