Description

Report presenting the effect on base pressure of bleeding air to the semidead-air region at the trailing edge of two-dimensional blunt-trailing-edge airfoils at two Mach numbers. Variation of base pressure with base-bleed rate was determined for two airfoils profiles with both laminar and turbulent boundary layers approaching the trailing edge. Results regarding the effects of jet geometry, effects of jet area, effect of base bleed on the flow in the wake, effect of angle of attack, effect of Reynolds number, correlation of the results with mass-flow rate of the bleed air, and effect of base bleed on the drag of ... continued below

National Advisory Committee for Aeronautics Collection

The National Advisory Committee for Aeronautics (NACA) was a U.S. federal agency founded on March 3, 1915 to undertake, promote, and institutionalize aeronautical research. On October 1, 1958 the agency was dissolved, and its assets and personnel transferred to the newly created National Aeronautics and Space Administration (NASA).
