Abstract
A numerical method is developed to analyse the flow around an axisymmetric ogive-cylinder and an ellipsoid-cylinder bodies undergoing harmonic pitching motion in an uniform air free stream. The pressure distributions along the lengthwise and over the circumference of the body are calculated with fineness ratio of 3:1 at mean angle of incidence 0° and 5°. Results are presented for a range of frequency parameters and various mean angle of incidence in order to show the influence of the frequency parameter and the mean angle of incidence on the aerodynamic properties.
