Abstract
Measuring apparatus including a core, interior to and stationary relative a spinning shell, having a cavity in sliding seal engagement with the interior of the spinning shell. The cavity is axially aligned with an aperture in the surface of the spinning shell, captures fluid pressure when the cavity and aperture are radially aligned and transmits the pressure to a transducer exterior to the aerodynamic test chamber.
Claims10
Apparatus for measuring surface pressure on a spinning body in an aerodynamic chamber comprising:
- a shell means having the configuration of said body and at least one aperture through the surface of said shell means;
- first positioning means connected to said shell means for rotating said shell means about the shell means' longitudinal axis;
- sensor means having a cavity in the interior of said shell means and aligned along said longitudinal axis with said aperture and a pressure transducer connected to said cavity, said sensor means measure the pressure at the point on the shell means surface defined by the radial alignment of said cavity and aperture.
