Acoustic and Aerodynamic Characteristics of Choral Singers
Journal of Voice, 2019The study aimed to investigate and compare the acoustic and aerodynamic characteristics of choral singers and nonsingers.Twenty choral singers and 20 nonsingers in the age range of 20-30 years with no vocal pathology participated in the study. For acoustic analysis, the voice sample was recorded and analyzed using Praat software (Phonetic Sciences ...

Aerodynamic Characteristics of Pressure-Pad Air Bars
4th International Symposium on Fluid-Structure Interactions, Aeroelasticity, Flow-Induced Vibration and Noise: Volume II, 1997Abstract Air flotation ovens are widely used for non-contact support and drying of coated papers and plastic films (generically called webs). The main components in air flotation ovens are air bars which have slot nozzles through which hot air jets are ejected.

Analysis on Aerodynamic Characteristics of a Paraglider Airfoil
Aerotecnica Missili & Spazio, 2016Paraglider sail (canopy) consists of a series of flexible boxes pressurized by special openings located at the leading edge, in the region near to the front stagnation point. Therefore, in order to avoid the deflation of the wing, the pressure inside the sail must remain above a certain threshold.

Aerodynamic Characteristics of Tracheostomy Speaking Valves
Journal of Speech, Language, and Hearing Research, 1999Two analyses were conducted to define some aerodynamic properties of one-way speaking valves designed for use with the tracheotomized patient. In the first analysis, the resistance to airflow of six different valves was determined during steady-state flow testing at rates of .450, .500, and .550 l/s.

Aerodynamic yawing moment characteristics of bird wings
Journal of Theoretical Biology, 2005The aerodynamic yawing moments due to sideslip are considered for wings of birds. Reference is made to the experience with aircraft wings in order to identify features which are significant for the yawing moment characteristics. Thus, it can be shown that wing sweep, aspect ratio and lift coefficient have a great impact.

Abstract : This study developed empirical methods to predict aerodynamic characteristics of body-tail, body-wing-tail and body-strake-tail missile configurations. Methods cover the Mach number range from 0.6 to 3.0. Methods cover the individual body and tail characteristics at angles of attack from 0 to 180 degrees.

Unsteady Aerodynamic Characteristics of Deformable Airfoil
1993The transient aerodynamic characteristics of a deformable two-dimensional airfoil during a stepwise incidence variation were studied experimentally. The instantaneous aerodynamic forces of the deformable airfoil were higher than those of the non-deformable one primarily due to the unsteady deflection of the deform-able airfoil.
