1 Introduction This paper is written to commemorate the sixtieth birthday of Paul Garabedian. While Paul has made broad ranging contributions in mathematics, fluid dynamics and plasma physics, his work on computational aerodynamics had a very forceful impact at a critical juncture in the development of this subject. I believe that this work should be regarded as being very much in the tradition...

An impact angle constrained fuzzy adaptive fault tolerant integrated guidance and control method for Ski-to-Turn (STT) missiles subject to unsteady aerodynamics multiple disturbances is proposed. Unsteady appears when flight vehicles are in a transonic state or confronted with unstable airflow. Meanwhile, actuator failures multisource model uncertainties introduced. However, the boundaries of t...

An aero-structural algorithm to optimize a flying wing in cruise conditions for preliminary design is developed using two-way interaction between the structure and aerodynamics. A particle swarm routine employed solve multi-objective optimization, aiming reduce weight of aerodynamic drag at point. Different shapes are evaluated during optimization process until reaches optimal aspect ratio, tap...

With advanced subsonic transports and military aircraft operating in the transonic regime, it is becoming important to determine the effects of the coupling between aerodynamic loads and elastic forces. Because aeroelastic effects can signiŽ cantly impact the design of these aircraft, there is a strong need in the aerospace industry to predict these interactions computationally.Such an analysis...

A large-scale, real-world application of Evolutionary MultiCriterion Optimization (EMO) is reported in this paper. The Multidisciplinary Design Optimization among aerodynamics, structures and aeroelasticity for the wing of a transonic regional jet aircraft has been performed using high-fidelity models. An Euler/Navier-Stokes (N-S) Computational Fluid Dynamics (CFD) solver is employed for the ae...

Abstract A major challenge when testing high-speed flows in turbomachinery applications concerns instrumentation intrusiveness. The current work exposes the impact of aerodynamic probes, placed upstream and downstream article, on aerodynamics a transonic low-pressure turbine blade investigated linear cascade at engine-representative outlet Mach Reynolds numbers. effect probe can be perceived as...

Abstract The vortex-dominated flow around the triple-delta wing ADS-NA2-W1 aircraft is investigated in order to achieve a better understanding of physics phenomena that occur over particularly at transonic speed condition. Both URANS and scale-resolving DDES have been employed explore range suitability current CFD methods. Spalart–Allmaras One-Equation Model with corrections for negative turbul...

This paper provides an up-to-date survey of the use of zonal detached eddy simulations (ZDES) for unsteady civil aircraft applications as a reflection on the stakes and perspectives of the use of hybrid methods in the framework of industrial aerodynamics. The issue of zonal or non-zonal treatment of turbulent flows for engineering applications is discussed. The ZDES method used in this article ...
