A Degradable Bioinspired Flier with Aerogel‐Based Colorimetric Sensors for Environmental Monitoring
Advanced Science, Volume 13, Issue 15, 13 March 2026.Biodegradable fliers are developed inspired by Tipuana tipu samaras, integrating cellulose nanocrystal aerogel (CNCa) sensors loaded with natural dyes for pH and ammonia detection. The lightweight, degradable fliers mimic natural morphology and aerodynamics, offering an eco‐friendly, scalable solution for in situ environmental monitoring after passive ...

Aerospace Engineering Undergraduate Laboratory Courses: A Systematic Review (1990–2025)
Computer Applications in Engineering Education, Volume 34, Issue 2, March 2026.ABSTRACT This review examines the evolution of undergraduate aerospace engineering (AE) laboratories from 1990 to 2025, focusing on course formats, pedagogy, technology, and assessment. Once centered on traditional demonstration‐based exercises, AE laboratories have increasingly shifted toward hands‐on, project‐based, and hybrid physical‐virtual models

Numerical Investigation of Transonic Axial Compressor Rotor With Leading‐Edge Tubercles
Engineering Reports, Volume 8, Issue 3, March 2026.Amplitude, wavelength, and span‐wise location of the leading‐edge tubercles on a transonic NASA Rotor 37 compressor are numerically optimized. An increase in efficiency by 0.52% compared to the corresponding baseline rotor is observed. The location of the shockwave moves downstream of the rotor with 1.91% higher pressure.

Unsteady Thin Airfoil Theory of a Biomorphing Airfoil [PDF]
Journal of the Korean Society for Aeronautical & Space Sciences, 2006 Birds and insect in nature morph their mean camberline shapes to obtain both lift and thrust simultaneously. Previous unsteady thin airfoil theories were derived mainly for a rigid flapping airfoil. An extended unsteady thin airfoil theory for a deformable airfoil is required to analyze the unsteady two-dimensional aerodynamic characteristics of a ...

Innovative Fluid Mechanics Education Through Augmented Reality and Interactive Learning
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.ABSTRACT Traditional pedagogical setups in laboratories are often outdated and do not provide the necessary support for effective learning. Teaching fluid mechanics poses additional significant challenges, particularly due to the need to visualize invisible properties, like velocity vector fields (velocity) or scalar pressure fields in time‐dependent ...
