AEROSPACE LETTERS are brief communications (approximately 2000 words) that describe new and potentially important ideas or results, including critical analytical or experimental observations that justify rapid publication. They are stringently prescreened, and only a few are selected for rapid review by an Editor. They are published as soon as possible electronically and then appear in the print version of the journal.read more

Recent progress in flapping wing aerodynamics and aeroelasticity
Wei Shyy,Hikaru Aono,Satish Kumar Chimakurthi,Pat Trizila,Chang-Kwon Kang,Carlos E. S. Cesnik,Hao Liu +6 more
TL;DR: In this article, a review of the recent progress in flapping wing aerodynamics and aeroelasticity is presented, where it is realized that a variation of the Reynolds number (wing sizing, flapping frequency, etc.) leads to a change in the leading edge vortex (LEV) and spanwise flow structures, which impacts the aerodynamic force generation.
Journal ArticleDOI
Effects of Flexibility on the Aerodynamic Performance of Flapping Wings
TL;DR: In this paper, the effects of chordwise, spanwise, and isotropic flexibility on the force generation and propulsive efficiency of flapping wings are elucidated, and a relationship between the propulsive force and the maximum relative wing tip deformation parameter is established.
Book
An Introduction to Flapping Wing Aerodynamics
TL;DR: In this article, the authors present an ideal book for graduate students and researchers interested in the aerodynamics, structural dynamics and flight dynamics of small birds, bats and insects, as well as of micro air vehicles (MAVs).
Journal ArticleDOI
Unsteady force generation and vortex dynamics of pitching and plunging aerofoils
TL;DR: In this paper, the effects of varying frequency and plunge amplitude for the same effective angle-of-attack time history are considered, and it is shown that for constant effective angle of attack, flow evolution is independent of Strouhal number, and as the reduced frequency is increased the leading edge vortex separates later in phase during the downstroke.
Journal ArticleDOI
Aerodynamics, sensing and control of insect-scale flapping-wing flight
TL;DR: In this paper, the authors reviewed advances in insect-scale flapping-wing aerodynamics, flexible wing structures, unsteady flight environment, sensing, stability and control are reviewed with perspective offered.

Fundamentals of Aerodynamics
TL;DR: In this article, Navier-Stokes et al. discuss the fundamental principles of Inviscid, Incompressible Flow over airfoils and their application in nonlinear Supersonic Flow.
Journal ArticleDOI
Wing rotation and the aerodynamic basis of insect flight.
TL;DR: In this paper, the authors show that the enhanced aerodynamic performance of insects results from an interaction of three distinct yet interactive mechanisms: delayed stall, rotational circulation, and wake capture.

Surrogate-based Analysis and Optimization
Nestor V. Queipo,Raphael T. Haftka,Wei Shyy,Tushar Goel,Rajkumar Vaidyanathan,P. Kevin Tucker +5 more
TL;DR: The multi-objective optimal design of a liquid rocket injector is presented to highlight the state of the art and to help guide future efforts.
Wing rotation and the aerodynamic basis of insect flight
TL;DR: A comprehensive theory incorporating both translational and rotational mechanisms may explain the diverse patterns of wing motion displayed by different species of insects.

Leading-edge vortices in insect flight
Charles P. Ellington,Coen van den Berg,Coen van den Berg,Alexander P. Willmott,Adrian L. R. Thomas,Adrian L. R. Thomas +5 more
TL;DR: In this article, the authors visualized the airflow around the wings of the hawkmoth Manduca sexta and a 'hovering' large mechanical model, and found an intense leading-edge vortex was found on the downstroke, of sufficient strength to explain the high-lift forces.
