Aerodynamic characteristics and parameters of the cone base region at transonic speeds

Aerodynamic characteristics and parameters of the cone base region at transonic speeds Abstract Aerodynamic characteristics of a sharp cone with the semi-apex angle of 15° are investigated by the methods of ballistic modelling in the Mach number range from 0.5 to 3.7, which are computed under the assumption of their almost linear behavior at the angles of attack up to 10°. Using the direct shadow pictures the geometric characteristics of near wake are measured and analyzed within the considered transonic and supersonic range. They provide the basis for semi-empirical computation of integral parameters of the base cavity: the pressure, density, and temperature. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Thermophysics and Aeromechanics Springer Journals

Abstract

Abstract Aerodynamic characteristics of a sharp cone with the semi-apex angle of 15° are investigated by the methods of ballistic modelling in the Mach number range from 0.5 to 3.7, which are computed under the assumption of their almost linear behavior at the angles of attack up to 10°. Using the direct shadow pictures the geometric characteristics of near wake are measured and analyzed within the considered transonic and supersonic range. They provide the basis for semi-empirical computation of integral parameters of the base cavity: the pressure, density, and temperature.
