适用范围
ESDU 80021 provides data for the pressure drag component of the forebody drag for families of ellipsoidal@ tangent ogive@ spherically-blunted tangent ogive and flat-faced forebodies with and without a radiused shoulder. The bodies are at zero incidence and at subsonic@ supersonic and hypersonic speeds up to Mach 10 except for the tangent ogive for which the data apply up to a Mach number of 4.5. The information is presented in graphical form@ and was obtained from correlations of experimental data and theoretical calculations for inviscid airflow.
