Some aspects of rocket propellant performances and solid rocket propellant development tendencies [PDF]

Vojnotehnicki glasnik, 2004
In order to increase pay loads in missile systems, research work in the domain of rocket propellants concentrates on conquering new, high-energy compositions providing a greater volume specific impulse. A short survey of rocket propellant development up to present days is followed by the most recent achievements in enhancing energy characteristics of ...

Analysis of viscoelastic behavior of a filled elastomer under action of different loads [PDF]

Hemijska Industrija, 2017
Mechanical properties of viscoelastic filled polymers strongly depend on temperature and strain rate and vary for several orders of magnitude. During service life, a viscoelastic body, especially carboxy-terminated polybutadiene (CTPB) composite solid ...

Large‐Scale Applications of Plasma Technologies: Progresses and Challenges

High Voltage, EarlyView.
ABSTRACT Plasma technologies convert electrical power into energetic electrons, ions, reactive species, radiation and heat, thereby breaking through the bottleneck of purely thermal or chemical routes and bringing impressive changes to our world. This roadmap reviews the progress and challenges of plasma technologies from a large‐scale and application ...

Reliability of solid rocket propellant grain under simultaneous action of multiple types of loads [PDF]

Scientific Technical Review, 2016
A case-bonded solid propellant rocket grain is subjected to many stress-inducing loads during the service life, due to temperature, extended polymerization, transportation, vibration, acceleration, aerodynamic heating etc.

Impulse and Performance Measurements of Electric Solid Propellant in a Laboratory Electrothermal Ablation-Fed Pulsed Plasma Thruster

Aerospace, 2020
Electric solid propellants are advanced solid chemical rocket propellants that can be controlled (ignited, throttled and extinguished) through the application and removal of an electric current.

Region‐of‐interest geometry optimization for shooting‐distance estimation from flash‐pulse infrared thermography of gunshot residue on textile targets

Journal of Forensic Sciences, EarlyView.
Abstract Shooting‐distance estimation from gunshot‐residue (GSR) patterns on textiles is affected by substrate properties, residue distribution, and region‐of‐interest (ROI) definition. This study evaluated how ROI geometry influences muzzle‐to‐target distance regression from flash‐pulse infrared thermography of GSR‐related thermal patterns.

Overview of Al-based nanoenergetic ingredients for solid rocket propulsion

Defence Technology, 2018
The introduction of nano-sized energetic ingredients first occurred in Russia about 60 years ago and arose great expectations in the rocket propulsion community, thanks to the higher energy densities and faster energy release rates exhibited with respect

Poetic Sociology

Sociological Forum, EarlyView.
ABSTRACT Can sociologists feel? Sociological writing can be beautiful, making us think differently about people, processes, and structures. Yet traditional academic writing that does this is rare. For example, most articles adhere to a jargon‐filled format and structure that mimics a detached and disciplined writer.

Effect of cyclic loads on structural damage of rocket propellant grain [PDF]

Scientific Technical Review, 2019
Rocket motor propellant grain, cast or bonded into the motor chamber or solid coating, is exposed to various loads during its service life. Rocket propellant is a viscoelastic material, whose mechanical properties strongly depend on temperature and ...

Tracing the Untraceable: A Review and Discussion on the Forensic Attribution of 3D‐Printed Firearms

WIREs Forensic Science, Volume 8, Issue 4, December 2026.
3D‐printed firearms are rapidly evolving and challenge traditional forensic identification. This review highlights emerging attribution methods, from deposition striae and base‐plate marks to polymer and GSR residual traces, firing marks, and quantitative imaging, identifying the research needed to support robust forensic attribution interpretation and
