In this paper, micro-spherical Al@PDA@RDX composites with fine interfacial control have been fabricated by spray-drying technique, where poly-dopamine (PDA) is employed as a binding layer. These composites have been applied in HTPB/AP/RDX/Al propellants,

Viscoelastic Properties of Inert Solid Rocket Propellants Exposed to a Shock Wave
Propellants, explosives, pyrotechnics, 2021Inert solid rocket propellant samples were subjected to dynamic inflation experiments, to characterize the viscoelastic response at high strain rates. An oxyacetylene-driven shock tube created the shock wave, which was used to dynamically pressurize the ...

Control the combustion behavior of solid propellants by using core-shell Al-based composites
, 2020Tailoring the combustion performance of propellant plays an important role in solid propellant design. Herein, we present that interfacial reaction (thermite reaction on Al surface) could be used for tuning the combustion performance of Al-based ...

Effect of metal additives on neutralization and characteristics of AP/HTPB solid propellants
, 2020Conventional ammonium perchlorate (AP) based solid propellant system has been used in rocket boosters and most tactile missiles. But the toxic chloride emissions from the combustion of AP during the rocket launch increase the air pollution by 1%. For the

A constitutive model of the solid propellants considering the interface strength and dewetting
, 2020The solid propellant as a typical viscoelastic composite, consists of oxidizer particles, fuel particles, and polymeric binders. After experiencing the service conditions under complex stress states and temperature cycles, solid propellants would be ...

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).

Efficient composite solid propellants possess stable burning rate (BR) and low-pressure exponents. To achieve the ideal performance of propellants, addition of burning rate catalysts (BRC) to the propellants system is one of the best choice.

Burning rate of artificially aged solid double-base gun propellants
Journal of Energetic Materials, 2020Nitrocellulose (NC) and nitroglycerin (NG) are conventional energetic ingredients of solid double-base gun propellants. NC and NG are aliphatic nitrate ester compounds that are manufactured by nitrating through immersion in acid.

Water skiing, boat racing, skin and scuba diving, and pleasure boat cruising are increasing in popularity. As a result the incidence of injuries secondary to motor propellers is becoming more frequent. In a ten-year period from 1963 to 1973, I collected a total of nine cases.
