Abstract : The work studies the non-constant supersonic flow around the wing-conical body system where the harmonic oscillatory movement is of low frequency. Considering the case of the harmonic rotation oscillations of pitching and rolling, as well as of translation along the vertical axis the problem is reduced through analogy with the case of detached wings to the study of constant conical movements of the order of 1 and 2 around the wing-conical body system. An expression of the coefficient of pressure is obtained with a view towards ascertaining the distribution of pressures upon the system under consideration. The problem studied is applicable to the development of supersonic aircraft. (Author)
