Abstract
The results of an experimental investigation into the variation of the shock wave shape and the extent of the subsonic region behind the shock with varying angle of attack at various Mach numbers are summarized. All tests are made on a finite 70° cone. The main interest is centered on those Mach numbers which are low enough to produce detached shocks or for which the possibility of detachment exists for increasing angles of attack. The angles of attack for which the investigation is made are 0°, 3°, 6°, 9°, 12° and 15°. The Mach numbers considered are 1.438, 1.544, 1.584, 1.857, 1.986, and 3.01. It is found that, for increasing angles of attack at constant Mach numbers, the extent of the subsonic region increases behind the lower shock and decreases behind the upper shock. A subsonic region appears at increased angle of attack for two of the Mach numbers for which the shocks are initially attached. There is also quite definite interaction between the upper and lower portions of the shock which tends to inhibit both the appearance of a subsonic region after the shock on the one hand and the disappearance of it on the other.
