Screening of polymer-plasticizer systems for propellant binder applications: an experimental and simulation approach

Journal of Energetic Materials, 2019
Composite propellants of advanced propulsion systems demand high energy, sufficient structural integrity, and low temperature capability. Polymers and plasticizers contribute to all these three important characteristics of propellants and they need to be

Effect of aluminum nanoparticles on rheological behavior of HTPB-based composite rocket propellant

Journal of Energetic Materials, 2018
The aim of this article was to understand the rheology of composite propellant containing aluminum nanoparticles, as it is a highly filled mixture of solids and is difficult to process. Aluminum nanoparticles utilized as a filler were characterized using

Rotating propeller soliton

Nonlinear Guided Waves and Their Applications, 2001
We demonstrate experimentally and theoretically (both analytically and numerically) a new type of spatial soliton: a rotating "propeller" soliton. This is a composite soliton made of a rotating dipole component jointly trapped with a bell-shaped component. We observe as much as 239 degrees of rotation over 13 mm of propagation (6.5 diffraction lengths).

Studies on ballistic parameters of di-butyl phthalate-coated triple base propellant used in large caliber artillery gun ammunition

Journal of Energetic Materials, 2018
Triple base propellant (TBP) containing mainly nitrocellulose, nitroglycerine, and nitroguanidine has been manufactured and coated with plasticizer in the present work. The aim was to study ballistics of di-butyl phthalate (DBP)-coated TBP.

Characteristics of a non-volatile liquid propellant in liquid-fed ablative pulsed plasma thrusters

, 2017
In the past several decades, the use of electric propulsion in spacecraft has experienced tremendous growth. With the increasing adoption of small satellites in the kilogram range, suitable propulsion systems will be necessary in the near future.

Toxicity of Propellants

1974
This report summarizes the available information on the toxicity of 15 propellants used in aerosols. After reviewing the results derived from various animal species, the following classifications are proposed: Low-pressure propellants of high toxicity: trichlorofluoromethane (FC 11), dichloromonofluoromethane (FC 21), trichlorotrifluoroethane (FC
