ABSTRACT:
Inner profile nozzle adapted for high temperature testing of specimens of the "plane board" type includes an axisymmetric convergent, a throat region, a divergent super-elliptic lying on two rectilinear generating lines taken along two perpendicular planes, including a small axis generating line having a slope of about 1.degree., and a long axis generating line having a slope of about 10.degree.. The throat region is provided with corresponding circular generating lines having downstream ends coupled with the small axis and the long axis generating lines by a curve obtained from an equation whose first and second derivatives are continuous, and whose third derivative is monotonic, so as to eliminate or reduce recompression problems and possible formation of shocks. This nozzle is particularly applicable to the high temperature testing of space vehicle materials.
