When an explosive detonates or a propellant or flare burns, consumption of the energetic filler should be complete but rarely is, especially in the presence of large amounts of non-combustible materials. Herein we examine three types of perchlorate-containing devices to estimate their potential as sources of contamination in their normal mode of functioning. Road flares, rocket propellants and ...

The NASA Exploration Systems Architecture Study (ESAS) produced a transportation architecture for returning humans to the moon affordably and safely while using commercial services for tasks such as cargo delivery to low earth orbit (LEO). Another potential utilization of commercial services is the delivery of cryogenic propellants to LEO for use in lunar exploration activities. With in-space p...

Petersen, P., Bredahl, E., Lauritsen, O., and Laursen, T. (1970). Brit. J. industr. Med., 27, 141-146. Examination of the liver in personnel working with liquid rocket propellants. Personnel working with liquid rocket propellants were subjected to routine health examinations, including liver function tests, as the propellant, unsymmetrical dimethylhydrazine (UDMH) is potentially toxic to the li...

We present a theoretical and computational framework for modeling the multiscale constitutive behavior of highly filled elastomers, such as solid propellants and other energetic materials. Special emphasis is placed on the effect of the particle debonding or dewetting process taking place at the microscale and on the macroscopic constitutive response. The microscale is characterized by a period...

Abstract 3D printing technology provides a new technical approach for the preparation of complex-type gun propellants. The filling pattern chosen printed propellants has an impact on mechanical strength In this paper, three patterns were used to print propellant samples. There is axial, radial and 45° straight pattern. tensile compressive samples with different compared studied. result shows th...

A capillary flow liquid acquisition device (LAD) for cryogenic propellants has been developed and tested in NASA Glenn Research Center to meet the requirements of transferring cryogenic liquid propellants from storage tanks to an engine in reduced gravity environments. The prototypical mesh screen channel LAD was fabricated with a mesh screen, covering a rectangular flow channel with a cylindri...

Chemical propellants are a type of fuel that commonly used in rocket engines to provide the thrust necessary for space exploration and satellite launches. They composed mixture chemicals react produce hot gas, which is then expelled from engine generate required force. An overview properties applications chemical propellants, including their composition, performance, environmental impact provid...
