| Abstract: | Supersonic perfect gas or equilibrium dissociated air flow past a sharp circular cone oscillating about a zero angle of attack is considered at small Strouhal numbers. The distribution of the gasdynamic parameters in the flow is found within the framework of the linear theory of finite-thickness bodies. The domain of the determining parameters for which the effect of equilibrium dissociation is substantial is found. The pitch moment coefficient related to the angular velocity of vibration is determined. Analytic expressions are derived for the gasdynamic characteristics at hypersonic flow velocities. Moscow.
