Self-adaptive cleaning technology for artillery laser ignition windows based on current feedback

Scientific Reports
Laser ignition is a novel artillery ignition technology. However, residues from propellant combustion adhere to the surface of the laser ignition window, obstructing the laser beam.

Analytical model for fast-shock ignition

AIP Advances, 2014
A model and its improvements are introduced for a recently proposed approach to inertial confinement fusion, called fast-shock ignition (FSI). The analysis is based upon the gain models of fast ignition, shock ignition and considerations for the fast ...

Corrosion Performance of Steel and Zinc‐Based Materials in Diverse Unsaturated Soils: Insights From a 2‐Year Field Exposure

Materials and Corrosion, EarlyView.
The present study generated the corrosion performance of C‐steel, zinc, and galvanized steel in different global unsaturated soil environments for 2 years. Acceptable matching was observed between corrosion rates and identified corrosion products. To properly predict soil corrosion, the results showed that DIN 50929 should include a drainage‐capability

Synthesis and Characterization of an Azido Nitrofurazanyl Ether: An Energy‐Rich Heterocyclic Plasticizer With a Low Glass Transition Temperature

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT We report on the synthesis and characterization of 3‐(2‐(2‐azidoethoxy)ethoxy)‐4‐nitro‐1,2,5‐oxadiazole (NFPEG2N3), which is a liquid nitrofurazanyl ether that was designed to be an energy‐rich plasticizer for glycidyl azide polymer (GAP)‐ and nitrocellulose (NC)‐based formulations.

Laser ignition studies [PDF]

, 1985
The goal of this work is to study the details of laser induced ignition and combustion of high-temperature condensed-phase exothermic reactions. In this work high-speed photography (HSP) and real-time optical pyrometry have been combined to provide a ...

Evaluation of a novel laser‐system operating at 1940 nm for weed control and determining the influence of biological and operational factors

Pest Management Science, EarlyView.
The control efficacy of a novel laser pulse system operating at 1940 nm was tested. The new system allows effective control of young weeds with 1.5 J. Targeting the plant stem is 53‐fold more energy‐efficient than the meristem. Species morphology and beam diameter significantly influence weed control efficacy. Abstract BACKGROUND This study evaluates a
