Abstract : The problem of flow over a circular cone inclined slightly to a uniform stream is solved using the technique of matched asymptotic expansions. The outer expansion is equivalent to Stone's solution of the problem. The inner expansion, valid in thin layer near the body, represents Ferri's vortical layer. The solution to first order in angle of attack so obtained is uniformly valid everywhere in the flow field. In the secondorder expansion an additional nonuniformity appears near the leeward ray. This defect is removed by inspection. The firstorder solution is in agreement with that of Cheng, Woods, Bulakh and Sapunkov. Formulas are given that may be used to render Kopal's numerical result uniformly valid to second order in angle of attack. A uniformly valid solution restricted to the hypersonic smalldisturbance approximation is also given. (Author)
