Aerodynamic characteristics of lambda wings
The Aeronautical Journal, 2000AbstractThe results of wind tunnel tests carried out on a semi-span ‘lambda’ planform model with leading and trailing edges swept at 40° are presented. The planform investigated has been specified as having features likely to be encountered on future ‘ow observable’ aircraft.

Method of calculation of aerodynamic and acoustic characteristics of aerodynamic profiles
2023The paper considers the theory of explaining the physical mechanisms of the occurrence of the trailing edge aerodynamic tonal noise of the airfoils. An analysis of the possibilities of using the ANSYS FLUENT software package for direct calculation of the aerodynamic and acoustic characteristics of airfoils in the near field is carried out using the ...

Aerodynamic characteristics of French consonants
The Journal of the Acoustical Society of America, 2004This paper reports some aerodynamic measurements made on French consonants with a group of ten speakers. Speakers were recorded while saying nonsense words in phrases such as papa, dis papa encore. The nonsense words in the study combined each of the French consonants with three vowels /i, a, u/ to from two syllables words with the first syllable being

Aerodynamic characteristics of rectangular cylinders in steady and accelerating wind flow
Journal of Fluids and Structures, 2019Aerodynamic actions on three two-dimensional rectangular cylinders were studied in steady and accelerating wind tunnel experiments. The aim of these experiments was to determine how body aerodynamics is modified during flow acceleration. The acceleration

Aerodynamic characteristics of avian airfoils
AIP Conference Proceedings, 2019This paper is focused on four bird’s airfoils namely Seagull, Merganser, Teal and Owl which are extracted from their respective wing cross-sections. In addition to this, the corrugation due to feather roughness of Swift bird is imposed on Seagull. The aerodynamic performance of these 4 avian airfoils and corrugated Seagull airfoil is tested in Reynolds

Aerodynamic characteristics of flexible wings with leading-edge veins in pitch motions
Aerospace Science and Technology, 2019To demonstrate the effects of wing deformations on aerodynamic performances during the wing reversal, aerodynamic force/torque and flow vector-fields were measured. Wing models consisted of wing planes with various thicknesses and two leading-edge veins,

Aerodynamic Characteristics of a Redesigned Turbine
Volume 6: Turbo Expo 2007, Parts A and B, 2007The aero-redesign of a 50 Hz Gas Turbine GT13D3A is presented. The modifications enabling performance improvements are described, and the aero-design process is briefly discussed as well. The aerodynamic characteristics of an upgraded turbine (GT13DM) are compared with the original design (GT13D3A) and with the measurements in the field.

Enhancement of aerodynamic characteristics in automobiles
2013 International Conference on Energy Efficient Technologies for Sustainability, 2013The aerodynamic characteristics directly affect the stability, driving characteristics, safety, operation, and oil consumption of automobiles. This study examines the aerodynamic drag force acting over the car body using CFD analysis and results were validated experimentally by conducting the wind tunnel test. The drag force acting over the car body is
