Analysis and test for space shuttle propellant dynamics: 1/60th scale model test results [PDF]
During the abort sequence, the ET and orbiter separate under aerodynamic loading, with propellant remaining in the ET. The separation event included a seven second decelerating coast period during which the residual propellant accelerates relative to the

Advanced Materials Interfaces, EarlyView.This review explores how various surface pretreatment methods—such as heat treatment, severe plastic deformation, laser modification, immersion, and cold spray—enhance the performance of PEO coatings on magnesium alloys. The study highlights how these pretreatments influence coating microstructure, adhesion, and corrosion resistance, offering new ...

Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.This article demonstrates that encasing a hyperelastic balloon in an inextensible sleeve greatly increases its burst pressure. This simple mechanical behavior can be used to produce an asymmetric inflation‐deflation sequence for coupled balloons with different thicknesses so they could serve as a soft robot's rear and front anchors when driven from a ...

Acoustic Analysis of Uneven Blade Spacing and Toroidal Geometry for Reducing Propeller Annoyance [PDF]
arXivUnmanned aerial vehicles (UAVs) are becoming more commonly used in populated areas, raising concerns about noise pollution generated from their propellers. This study investigates the acoustic performance of unconventional propeller designs, specifically toroidal and uneven-blade spaced propellers, for their potential in reducing psychoacoustic ...
