Aerodynamic lift is used during re-entry to provide range maneuverability so that a precise site can be selected and a horizontal landing capability can be provided. Maximum maneuverability may be achieved by modulating the hypersonic lift-to drag ratio (L/D). In this study the lifting re entry configuration was optimized to maximize hypersonic L/D within the heating, stability, and landing constraints. Eleven pertinent constraint equations were formulated, and numerical calcula tions of the complete aerodynamic characteristics and configurational geometry were determined. The IBM 7090 computer was used to solve the 11 constraint equations through an iteration tech nique and to perform the maximization process. Optimum configurational geometries were evaluated for three wing loadings at vehicle weights of 10,000 and 100,000 pounds. Results show that higher L/D values can be achieved with low aspect ratio, low wing loadings, and large scale vehi cles. The complete geometry for one of the typical optimums is shown as an example.

In a series of newly commissioned essays from the leading scholars and advocates in criminal justice, Invisible Punishment explores, for the first time, the far-reaching consequences of our current criminal justice policies. Adopted as part of “get tough on crime” attitudes that prevailed in the 1980s and '90s, a range of strategies, from “three strikes” and “a war on drugs,” to mandatory sentencing and prison privatization, have resulted in the mass incarceration of American citizens, and have had enormous effects not just on wrong-doers, but on their families and the communities they come from. This book looks at the consequences of these policies twenty years later.
