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.

Test Results for a Reciprocating Pump Powered by Decomposed Hydrogen Peroxide.

DE200515013360

Publication Date	2001
Personal Author	Whitehead, J. C.
Page Count	14
Abstract	A four-chamber piston pump has been tested in several evolving configurations. A significant improvement over an earlier hydrazine pump is the elimination of warm gas leakage in the powerhead. This has been achieved through the use of soft seals for the power piston and intake-exhaust valves, with gas temperatures approaching 800 K (980 F). The pumped fluid serves as a coolant, and the cylinder walls and heads are made of aluminum for high thermal conductivity, low mass, and affordability.
