Aerodynamic Optimization of an Aerial Pod

2020 Advances in Science and Engineering Technology International Conferences (ASET), 2020
The incompressible, steady, turbulent flow around an external aerial pod was analyzed in order to optimize the pod's geometry for minimum drag, which is important to reduce its effect on the aircraft's performance. The computations were conducted in a 2-dimentional axisymmetric and 3-dimentional computational domains using ANSYS-Fluent k-ω SST ...

Cooling and Aerodynamics Simultaneous Optimization

SAE Technical Paper Series, 1991
<div class="htmlview paragraph">Beginning from the mid-70's a clear trend emerged in car aerodynamic design and styling which dictated the lowering of the hood profile and a corresponding reduction of grill openings, while the nose surface remained dedicated to the bumper impact area and car number plate. On the other hand the increasing power of

Aerodynamic optimization using proficient optimization algorithms

2012 International Conference on Computing, Communication and Applications, 2012
Nowadays engineering analysis relies heavily on computer-based solution algorithms to investigate the performance of an engineering system. Computational fluid dynamics (CFD) is one of the computer-based solution methods which are more widely employed in aerospace engineering.

UNCERTAINTY BASED ROBUST OPTIMIZATION IN AERODYNAMICS

Modern Physics Letters B, 2009
The Taguchi robust design concept is combined with the multi-objective deterministic optimization method to overcome single point design problems in Aerodynamics. Starting from a statistical definition of stability, the method finds, Nash equilibrium solutions for performance and its stability simultaneously.

Perching aerodynamics and trajectory optimization

SPIE Proceedings, 2007
Advances in smart materials, actuators, and control architecture have enabled new flight capabilities for aircraft. Perching is one such capability, described as a vertical landing maneuver using in-flight shape reconfiguration in lieu of high thrust generation.

Aerodynamic design via optimization

Journal of Aircraft, 1992
An aerodynamic design optimization method is presented that generates an airfoil, producing a specified surface pressure distribution at a transonic speed. The design procedure is based on the coupled Euler and boundary-layer technology to include the rotational viscous physics which characterizes transonic flows.

Aerodynamic optimization with evolutionary algorithms

UKACC International Conference on Control. Control '96, 1996
Characteristics of aerodynamic optimization are discussed through a simplified airfoil design problem. Three optimization algorithms, the gradient-based method, simulated annealing and genetic algorithm, have been applied to the airfoil shape design using the approximation concept to compare their performance.

Aerodynamic Optimization of an UAV Design

AIAA 5th ATIO and16th Lighter-Than-Air Sys Tech. and Balloon Systems Conferences, 2005
The Maracaibo Lake, Venezuela, is an important petroleum extraction region and besides it is a source of constant pollution. However, the early detection of the oil leakages minimizes the environment impact. In 2003 an UAV for the special mission of patrolling that region in search for oil leakages was designed.
