Optimization in Conceptual Design of a BWB UAV Using an Adaptive Kriging‐Based Surrogate Model

Engineering Reports, Volume 8, Issue 2, February 2026.
An adaptive Kriging‐based framework for Blended Wing Body UAV optimization is presented. The exploitation‐oriented strategy yields a 14.5% range improvement, while sensitivity analysis identifies fuel mass as the dominant parameter for efficient conceptual design. ABSTRACT To improve optimization efficiency in the conceptual design of Blended Wing Body

Experiences with optimizing airfoil shapes for maximum lift over drag [PDF]

The goal was to find airfoil shapes which maximize the ratio of lift over drag for given flow conditions. For a fixed Mach number, Reynolds number, and angle of attack, the lift and drag depend only on the airfoil shape.

Development of a Novel Modified Mean‐Line Approach for Performance Prediction of Axial Compressors

Energy Science &Engineering, Volume 14, Issue 2, Page 843-853, February 2026.
ABSTRACT There is significant importance in accurate prediction of axial flow compressor characteristics at different conditions. Different techniques and models have been proposed for performance prediction of axial compressors. Because of its lower computational cost and high speed the meanline algorithm has been widely applied in preliminary design ...

Failure Criterion‐Based Bead Optimization of a Wind Turbine Blade Root Section

Wind Energy, Volume 29, Issue 2, February 2026.
ABSTRACT This study presents a bead‐based optimization framework for fiber composite wind turbine blades, employing the Tsai–Wu failure criterion as the structural performance measure. The objective is to design an optimal transition geometry between an existing blade and a root section with 20% smaller diameter, while preserving the original material ...

Shrouded Wind and Water Turbine Analytical Model Extensions for Tip Gaps, Center Bodies, and Flow Blockage

Wind Energy, Volume 29, Issue 2, February 2026.
ABSTRACT This paper provides improvements to a previously presented simple, accurate, lower order analytical model for predicting the performance of horizontal‐axis shrouded turbines for a wide range of shroud airfoil shapes varying in length, camber, and thickness. The new, extended model incorporates explicit quantitative predictions of those effects
