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.

Lithium Spray Structural Cooling.

AD451274

Publication Date	1964
Personal Author	Mistretta, A. L.
Page Count	120
Abstract	The objective of this program was to demonstrate the feasibility of an open cycle lithium spray absorptive cooling system for nose cap applications and to determine maximum heat flux capability of the system. Test specimens were designed and fabricated. The experimental program which was established demonstrated the feasibility of the lithium spray system. While subjected to a heat flux of 600 BTU/sq ft-sec, equivalent to a radiation equilibrium temperature of about 5800 F, specimen surface temperature did not exceed 2200 F. Instrumentation difficulties precluded tests at higher heat fluxes; therefore, the maximum potential of the system could not be determined experimentally. Approximate analytical estimates indicate a minimum potential capability of 3000 BTU/sq ft-sec. (Author)
