ACCELERATED AIRFOIL OPTIMIZATION VIA VIBRATIONAL GENETIC ALGORITHM
Havacılık ve Uzay Teknolojileri Dergisi, 2003 Transonic airfoil optimization is made for drag minimisation through shock wave reduction. In this study, a new approach to genetic algorithms, called Vibrational Genetic Algorithm (VGA), is used for transonic airfoil optimization.

Viscous effects on transonic airfoil stability and response [PDF]
Viscous effects on transonic airfoil stability and response are investigated using an integral boundary layer model coupled to the inviscid XTRAN2L transonic small disturbance code. Unsteady transonic airloads required for stability analyses are computed

Advanced Functional Materials, EarlyView.High‐density BNNT films, enabling mechanical robustness and high space radiation shielding effectiveness, are fabricated using surfactant‐stabilized BNNT liquid crystal. Simulations indicate that a 50 g cm−2 BNNT film can reduce radiation exposure by 56% compared to zero shielding, potentially doubling the duration of astronaut missions on the lunar ...

Analysis of the Transonic Buffet Characteristics of Stationary and Pitching OAT15A Airfoil
Applied SciencesTransonic buffet flow is a classical complex and unstable flow that has a negative effect on aircraft fly safety. Therefore, it is crucial to study the unsteady characteristics of buffet flow. The numerical analysis method is very useful in achieving the

Unsteady transonic flow calculations for interfering lifting surface configurations [PDF]
Unsteady transonic flow calculations are presented for aerodynamically interfering lifting surface configurations. Calculations are performed by extending the XTRAN3S (Version 1.5) unsteady transonic small-disturbance code to allow the treatment of an ...

Advanced Functional Materials, EarlyView.This paper synthesizes CuO@CuCo2O4 catalysts via an emulsion hydrothermal method. Among them, CuCuCo2O4 perfectly inherits the advantages of CuO and Co3O4 and successfully connects the reactions in series. During the electrolysis process, CuO is reduced to Cu.
