Aerodynamic characteristics of biplanes with winglets

Journal of Aircraft, 1987
This paper examines, both theoretically and experimentally, the possibility of improving the aerodynamic characteristics of a biplane configuration by adding winglets. Theoretical calculations show good agreement with experiment in predicting inviscid drag due to lift.

Aerodynamic characteristics of trills and phonological patterning

Journal of Phonetics, 2002
Abstract The present study attempts to characterize the aerodynamic conditions required for the production of apical trills and to account for some universal tendencies in the patterning of trills in terms of their aerodynamic and distinctiveness requirements.

Determination of Elastic Wing Aerodynamic Characteristics

Journal of the Aeronautical Sciences, 1952
The basic aeroelastic integral equation is formulated by treating the wing as a tapered cantilever beam mounted normal to its straight elastic axis. By means of an iterative process, a series solution is obtained for the aeroelastic change in angle-of-attack distribution. For sweptback wings, this Neumann solution fails to converge at dynamic pressures

Aerodynamic Characteristics of Rectangular Cylinders

International Journal of Computational Fluid Dynamics, 1999
Three and two-dimensional simulations of unsteady flows around a rectangular cylinder sectioned object are carried out by means of the IBTD + FS Finite Element technique without the use of a turbulence model. The three-dimensional simulations confirmed that the aerodynamic characteristics of a rectangular object with a side ratio of breadth/ depth (B/D)

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.

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 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.

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 ...
