Low and high velocity clouds produced by young stellar clusters [PDF]
, 2009 Intermediate and high velocity HI clouds rain onto the plane of our Galaxy. They are observed at heights of between 500 and 1500 pc, falling onto the Galactic plane at velocities from 50 to 140 km s$^{-1}$. To explain the origin of these clouds, we present a galactic fountain model, driven by the wind from a super stellar cluster (SSC).

Throttleable Solid Propellants Through Embedded Shape Memory Alloy and Resistance Wires
Propellants, Explosives, Pyrotechnics, Volume 50, Issue 3, March 2025.Throttling behavior of expanding propellants ABSTRACT Solid propellants are used in propulsion systems for their high performance, feasibility to manufacture, long shelf life, and ease of storage and handling; however, they are limited by the inability to actively control the burning rate.

A Study of an Asymmetric Flow in an Overexpanded Rocket Nozzle
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 2006 This paper presents an investigation of the unsteady three-dimensional flow in an overexpanded rocket nozzle during a shutdown transient. Experimental and numerical investigations were carried out. It is known that, in some cases, an asymmetric flow induces a serious lateral force called “side load” during transient operations. The focus of
