Abstract: A fluid sensing device includes an outer body having a fore side, an aft side, and an interior space, the outer body including a fluid inlet disposed at the fore side; an inner body extending at least partially out of the fluid inlet of the outer body along a longitudinal axis; one or more vents disposed aft of the fluid inlet to allow passage of fluid through the fluid sensing device; and at least one load sensor coupled to the inner body to measure a fluid drag force on the inner body, wherein the inner body is configured to induce the Coanda effect in at least a portion of a fluid contacting the inner body at an angle transverse to a longitudinal axis of the inner body.

Abstract: A fluid sensing device includes an outer shell, a three-axis force and moment balance, a strut, and a centerbody. The outer shell has an inlet at a first end of the outer shell, an aft vent at an opposing second end of the outer shell, and an interior space connecting the inlet and the aft vent. The three-axis force and moment balance is positioned in the interior space of the outer shell. The strut is connected to the outer shell and the three-axis force and moment balance such that the strut supports the three-axis force and moment balance in the interior space. At least a portion of the centerbody is positioned in the interior space of the outer shell. The centerbody is connected to the three-axis force and moment balance such that the three-axis force and moment balance is configured to measure force, moment, and/or movement of the centerbody.

Abstract: A fluid sensing device includes an outer body, an inner body coupled to the outer body by one or more inner body support struts and extending at least partially out from the outer body, and an aft body disposed at least partially within the outer body at a location aft of the inner body, the aft body being coupled to the outer body by one or more aft body support struts. The inner body includes a hollow interior for housing one or more inner body sensors, and the aft body houses one or more aft body sensors. The fluid sensing device can measure one or more parameters of fluid flow at high angularity, such as total temperature and total pressure, locally and simultaneously, allowing additional fluid parameters, such as local entropy, to be calculated.

Abstract: A vortex generator for attenuating flow separation which occur during supersonic flow of air over structure such as an aircraft airfoil, its fuselage, surfaces forming a part of a jet propulsion unit, turbine or compressor blades, or similar surfaces subjected to supersonic airflow. A series of vortex generators are provided each of which comprises a cavity in the component over which the supersonic air is flowing that is configured to generate a spiral vortex which attenuates flow separation and weight drag resulting from the supersonic airflow. Each cavity is of generally triangular configuration defined by two side walls which diverge in a direction away from the apex of the triangular cavity, and a flat bottom wall joined to the side walls. In an alternate embodiment, means is provided for selectively shifting the bottom wall from a retracted inner position, to an outer location essentially flush with the surface over which the supersonic airflow is occurring.
