Boundary-layer Similar Solutions and Correlation Equations for Laminar Heat-transfer Distribution in Equilibrium Air at Velocities Up to 41,100 Feet Per Second


Book Description

Correlations of the transport property estimates of NASA TR R-50 are employed to determine locally similar solutions of the laminar boundary-layer equations for air in chemical equilibrium. Exact solutions for flat-plate flow, axisymmetric stagnation flow, and stagnation flow for yawed infinite cylinder are obtained, and a correlation formula for the heat-transfer distribution function for arbitrary favorable pressure gradient is determined. Extension to three-dimensional flows with small cross flow is briefly described.

Proceedings of Retardation and Recovery Symposium


Book Description

This report contains the proceedings of the Retardation and Recovery Symposium sponsored by the Aeronautical Systems Division on 13 and 14 November 1962. The Introductory Session was opened with the Keynote Address which reviewed the use and applications of deployable aerodynamic decelerators throughout the past fifty (50) years and noted the areas in which additional work had to be accomplished. The four Technical Sessions deal with the latest significant developments in the retardation and recovery area. The Technical Sessions begin with presentations and discussions of investigations in the hypersonic and supersonic flight regimes followed by a technical analysis of transonic and supersonic flow phenomena. In addition, new aerodynamic decelerator designs and discussion of the wind tunnel tests pertaining to these designs, as well as overall reliability of recovery systems, are presented. The final Technical Session concludes with a discussion of the military, scientific, and general objectives for decelerators intended for future use.
