Hydraulic characteristics of flow through miniature slits
Hydraulic characteristics of micro-orifices arrayed in close proximity across the face of a liquid fuel injector are studied. Effects of geometry and flow variables on discharge coefficients and flow regimes are determined, as well as visible characteristics of the emerging liquid streams
Injector has no backsplash
Passages of injector have been modified to eliminate backsplashing. All fluid is expelled in downstream spray fan. Result is that face of injector is completely free of liquid obstructions
Statistical analysis of a planetary radar altimeter measuring unit
Statistical analysis of altitude measuring unit of lightweight continuous wave radar altimete
Entry dynamics of space shuttle orbiter with longitudinal stability and control uncertainties at supersonic and hypersonic speeds
A six-degree-of-freedom simulation analysis was conducted to examine the effects of longitudinal static aerodynamic stability and control uncertainties on the performance of the space shuttle orbiter automatic (no manual inputs) entry guidance and control systems. To establish the acceptable boundaries, the static aerodynamic characteristics were varied either by applying a multiplier to the aerodynamic parameter or by adding an increment. With either of two previously identified control system modifications included, the acceptable longitudinal aerodynamic boundaries were determined
