Aerodynamic characteristics of lambda wings

The Aeronautical Journal, 2000
AbstractThe 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.

Aerodynamic Characteristics of a Redesigned Turbine

Volume 6: Turbo Expo 2007, Parts A and B, 2007
The 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.

Method of calculation of aerodynamic and acoustic characteristics of aerodynamic profiles

2023
The 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, 2004
This 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 Blerak Winglet

Journal of Advanced Research in Fluid Mechanics and Thermal Sciences, 2023
The induced drag created by wingtip vortices has a significant impact on aircraft performance. Winglets are wingtip extensions that are intended to reduce the creation of vortices and increase the fuel efficiency. The present study is based on analyzing different winglets planform for aircraft at various angles of attack (AOA) to improve the ...

Enhancement of aerodynamic characteristics in automobiles

2013 International Conference on Energy Efficient Technologies for Sustainability, 2013
The 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

Aerodynamic Characteristics of a Gyroplane Configuration

Journal of Aircraft, 1998
We describe the wind-tunnel testing of a scale model gyroplane in the 3-m Low-Speed Wind Tunnel at the Aeronautical Research and Test Institute, Prague. These tests were conducted by the University of Glasgow as part of a U.K. Civil Aviation Authority funded research program into gyroplane airworthiness and flight safety.

Aerodynamic characteristics of avian airfoils

AIP Conference Proceedings, 2019
This 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
