Analytical Design of a Family of Supersonic Nozzles by the Friedricks Method (Including Computation Tables and a Summary of Calibration Data)

摘要

The design procedure for the family of supersonic nozzles in use at the Naval Supersonic Laboratory of the Massachusetts Institute of Technology is herein pre¬sented. The basis for the potential-flow design is the analytic method first outlined by Friedrichs, to which ha8 been added some results which furnish a higher order of approximation to the nozzle contour. The implied mathematical convergence in the method is discussed and reference is made to continuous curvature streamlines. The accumulated computations of the Laboratory are tabulated for the convenience of those wishing to avail themselves of the family of contours successfully used.. Experimental results .from calibrations conducted within the uniform flow region and at the nozzle boundaries are presented, and interpretations are given in terms of the" design, fabrication, measurement accuracy, and model requirements
