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

Hybrid Deep Learning‐Based Networks for Deterministic and Probabilistic Wind Nowcasting Within a Wake Vortex Warning System for Vertiport Operations

Meteorological Applications, Volume 33, Issue 2, March/April 2026.
This paper proposes an innovative framework for deterministic and probabilistic wind nowcasting consisting of various machine learning methods. The reliable short‐term wind predictions drive the Wake Vortex Warning System for Vertiports (WVWS‐V), which may enable safe air‐taxi operations at major airports. ABSTRACT Accurate wind prediction is essential
