Abstract : The objective of this study is to compare approximate techniques for predicting shock detachment distance in two-dimensional supersonic inlets. The motivation for such a comparison arises from the need to determine more accurately the ramp pressure contribution to supersonic additive drag. Four methods for estimating bow shock position are presented and compared with experimental data from a 20% model of the B-1 external compression supersonic inlet. Static pressure data taken on the third ramp of the B-1 inlet model yield an effective bow shock position with which to compare the prediction procedures. (Modified author abstract)
