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 usd-5\sp\circusd to 30 as well as the correlation between the surface flow visualization and the surface pressure distribution. This investigation also includes Pitot response measurement, jet calibration and Pitot pressure measurement along the free jet axis. The normal force was measured using a strain-gage. Results showed that for positive angles, the actual force coefficient CFS was larger than the one predicted theoretically, especially at angles usd0\le 20\sp\circusd where the deviation was larger than 25%. Moreover, the results of the comparative case with Lamont and Hunt (2) at 0 = 30 were in good agreement.
