National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Behavior of Plastic Materials in Hyperthermal Environments.

AD237362

Publication Date	1960
Personal Author	SCHMIDT, D. L.
Page Count	1
Abstract	A systematic investigation of the behavior of plastic materials in very high temperature air is reported. Several test models of various compositions and constructions were exposed in the air plasma of a one megawatt stabilized electric arc. Both descriptive and quantitative data were obtained on the characteristics and physical properties of the ablative materials. A thermal analysis of quasi steady-state ablation at the stagnation point of the test models was performed. Individual heat transfer parameters were numerically estimated for the plastic materials and test conditions under consideration. (Author-PL).
