Abstract : Drag coefficients for two-dimensional strips normal to the flow have been determined experimentally at Mach numbers of 6.22, 8.12, and 10.09 by means of the free-jet testing technique. The free stream Knudsen number ranges from about 1 to 30. Results obtained are compared to the nearly free-molecule flow theory proposed by Willis. A number of special tests were performed to demonstrate the validity of the free-jet experimental technique and to determine the feasibility of further application of this valuable testing method.
