Abstract : Heat-transfer and pressure distributions were measured on sharp and blunt 15 degree half-angle cones. The flow was near conical on the windward side of the models up to an angle of attack of about 60 degrees. At angles of attack above 70 degrees the flow departed noticeably from conical characteristics. Heat-transfer and pressure measurements were found to agree satisfactorily with theories of simple application. At large angles of attack the effects of nose bluntness are very small in the region beyond two nose radii from the point of tangency. (Author)
