English Abstract

The normal force and pressure distribution acting on a flat plate resulting from underexpanded supersonic jet impingement at angles lower than 20° has never been experimentally investigated. The objectives of the present investigation are to study the normal force coefficient and pressure distribution on a flat surface at angles from -5° to 30° as well as the correlation between the surface flow visualization and the surface pressure distribution. This investigtion also includes Pilot response measurement, jet calibration and Pilot pressure measurement along the free jet axis. The normal force was measured using a strain guage. Results showed that for positive angles, the actual force coefficient C was larger than the one predicted theoretically, especially at angles 0< 20° where te deviation was larger than 25%. Moreover the results of the comparative case with Lament and Hunt at 0=30° were in good agreement.
