Preliminary calibration of a generic scramjet combustor [PDF]
The results of a preliminary investigation of the combustion of hydrogen fuel at hypersonic flow conditions are provided. The tests were performed in a generic, constant-area combustor model with test gas supplied by a free-piston-driven reflected-shock ...

Malthusian dynamism and the rise of Europe: Make war, not love [PDF]
This paper argues that Malthusian regimes are capable of sustained changes in per capita incomes. Shifting mortality and fertility schedules can lead to different steady-state income levels, with long periods of growth during the transition.

Wind tunnel investigation of an all flush orifice air data system for a large subsonic aircraft [PDF]
The results of a wind tunnel investigation on an all flush orifice air data system for use on a KC-135A aircraft are presented. The investigation was performed to determine the applicability of fixed all flush orifice air data systems that use only ...
