A Model for Igniter Mass Flow Rate History Evaluation for Solid Rocket Motors
International Journal of Aerospace Engineering, 2019 This paper describes a zero-dimensional model for evaluating the mass flow rate history of a solid rocket motor igniter. Based on the results of an igniter-firing experiment, in which the igniter is the only source of combustion gas and no propellant is ...

Sustainability and Scope: A Comparative Study of Discretion Making for Sustainability
Business Strategy and the Environment, EarlyView.ABSTRACT The measurability of sustainability is a subject of ongoing debate. Discretion is an important antecedent to such valuation yet remains largely unaddressed. Thus, we conduct a cross‐case study of four organizations, finding differences between product and service firms in how they define their sustainability discretion, which is shaped by and,

Plasmakristall‐4 Experiment: 10 Years of Operation in Orbit
Contributions to Plasma Physics, EarlyView.ABSTRACT Plasmakristall‐4 (PK‐4) is a microgravity complex plasma laboratory operated for 10 years on board the International Space Station. Its main purpose is the particle‐resolved investigation of generic condensed matter phenomena using strongly coupled suspensions of microparticles immersed in low‐pressure gas‐discharge plasmas.

Stopping Power of Electron Liquid for Slow Quantum Projectiles
Contributions to Plasma Physics, EarlyView.ABSTRACT We revisit the problem of the deceleration of a charge moving in a medium. In the low‐velocity limit of the projectile, we construct the fully nonlinear (in the charge–target interaction) theory of the stopping power (SP), which goes beyond the classical Ehrenfest dynamics.

InfoMat, EarlyView.Improving the dispersion of nano‐aluminum is of great importance in explosives and propellants. The spherical Al/HMX/CuO energetic micro‐units were prepared using microchannel technology, which significantly improved the uniformity and dispersion of nano‐Al. It also enhanced the mass and heat transfer efficiency between the fuel and oxidizer components,
