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

Aerodynamics and aeroacoustics of flap side-edges [PDF]

, 2008
An experimental and computational investigation was carried out to determine the aerodynamics and aeroacoustics of a flap side-edge. A porous side-edge treatment was applied to the flap side-edge in an attempt to reduce airframe noise. Measurements taken

The effects of viscosity on sound radiation near solid surfaces

, 2011
Although the acoustic analogy developed by Lighthill, Curle, and Ffowcs Williams and Hawkings for sound generation by unsteady flow past solid surfaces is formally exact, it has become accepted practice in aeroacoustics to use an approximate version in ...

A benchmark case for aeroacoustic simulations involving fluid-structure-acoustic interaction transferred from the process of human phonation

Acta Acustica
Modeling fluid-structure-acoustic interaction is a highly challenging task and currently there is a lack of available benchmark datasets. For instance, to understand the processes of human phonation, it is essential to fully understand the fluid ...

Control of aerodynamic noise from cascade of flat plates by plasma actuators

Nihon Kikai Gakkai ronbunshu, 2017
At specific velocities, intense noise can be generated by the flow around a cascade of flat plates due to acoustic resonance. To reduce the aerodynamic noise, dielectric barrier discharge (DBD) plasma actuators (PAs) were utilized.
