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.

Determination of Elastic Wing Aerodynamic Characteristics
Journal of the Aeronautical Sciences, 1952The 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 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 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 hypersonic wakes.
AIAA Journal, 1967A comprehensive experimental program has been conducted in the ballistics range facilities of the U. S. Naval Ordnance Laboratory to determine various aerodynamic characteristics of wakes behind hypervelocity bodies. The effects of Mach number, Reynolds number, and wall-to-stagnation enthalpy ratio on base flow geometry and transition from laminar to ...

Aerodynamic Characteristics of Rectangular Cylinders
International Journal of Computational Fluid Dynamics, 1999Three 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)
