Acoustic Boundary Conditions for Can-Annular Combustors
International Journal of Turbomachinery, Propulsion and Power, 2023 This paper derives and validates an analytical model for acoustic boundary conditions on a can-annular gas turbine combustion system composed of discrete cans connected to an open annulus upstream of a turbine.

TreeSpider: In‐Canopy Exploration With Tether‐Based Aerial Modular Arms
Advanced Robotics Research, Volume 2, Issue 2, April 2026.A tethered drone with perching arms and a 360° ring enables unprecedented maneuverability within dense forest canopies. By dynamically adjusting tether length and decoupling pitch from the frame, it navigates between branches, senses multiple trees, and interacts physically with foliage.

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.

Survey of Semi-Empirical Jet Noise Models for Preliminary Aircraft Engine Design
Aerospace, 2023 Scientific research studies on jet noise generation have been ongoing since the early 1950s, when turbojets were first used in commercial aircraft. Several numerical methods have been developed with the aim of reducing the environmental issues related to

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

The Technique of MIEELDLD in Computational Aeroacoustics [PDF]
Journal of Applied Mathematics, 2012 The numerical simulation of aeroacoustic phenomena requires high‐order accurate numerical schemes with low dispersion and low dissipation errors. A technique has recently been devised in a Computational Fluid Dynamics framework which enables optimal parameters to be chosen so as to better control the grade and balance of dispersion and dissipation in ...
