NACA-TR-D-894: On similarity rules for transonic flows
Abstract: A method used by Tsien to derive similarity rules for hypersonic flows is utilized to derive Von Karman's similarity rules for transonic flows. At the lower limit of the transonic region of flow the theory yields a formula ...
NACA REPORT 874: A Simplified Method of Elastic Stability Analysis for Thin Cylindrical Shells
Abstract: This paper develops a new method for determining the buckling stresses of cylindrical shells under various loading conditions. In part I, the equation for the equilibrium of cylindrical shells introduced by Donnell in NACA ...
NACA-TR-1170: Behavior of materials under conditions of thermal stress
Abstract: A review is presented of available information on the behavior of brittle and ductile materials under conditions of thermal stress and thermal shock. For brittle materials, a simple formula relating physical properties to ...
NACA-TR-899: A General Small-Deflection Theory for Flat Sandwich Plates
Abstract: A small-deflection theory is developed for the elastic behavior of orthotropic flat plates in which deflections due to shear are taken into account. In this theory, which covers all types of flat sandwich construction, a ...
NACA-TR-D-1201: Performance and boundary-layer data from 12 degree and 23 degree conical diffusers of area ratio 2.0 at Mach numbers up to choking and Reynolds numbers up to 7.5 x 10(6)
Abstract: For each of two inlet-boundary-layer thicknesses, performance and boundary-layer characteristics have been determined for a 12 degree, 10-inch-inlet-diameter diffuser, a 12 degree, 21-inch-inlet-diameter diffuser, and a ...
NACA-TR-737: Bending of Rectangular Plates with Large Deflections
Abstract: The solution of Von Karman's fundamental equations for large deflections of plates is presented for the case of a simply supported rectangular plate under combined edge compression and lateral loading. Numerical solutions ...
NACA-TN-2836: Radiant-interchange configuration factors
Abstract: A study is presented of the geometric configuration factors required for computing radiant heat transfer between opaque surfaces separated by a nonabsorbing medium and various methods of determining the configuration factors ...
