Nonlinear Aeroelasticity and Unsteady Aerodynamics

AIAA Journal, 2002
In this von Karman lecture, a subject is addressed whose foundations were significantly influenced by the work of Theodore von Karman. A classic paper by von Karman and Sears first considered the determination of aerodynamic forces on an airfoil undergoing general time-dependent motion.

Gurney flap aerodynamic unsteadiness

Sports Engineering, 1999
A Gurney flap is a thin strip of material attached at the trailing edge of the upper surface of a racing car wing in order to increase the downforce of a wing of limited size. The flow around a single element racing car wing with and without a 4.7% Gurney flap has been investigated experimentally and computationally.

New Frequency Parameter for Unsteady Aerodynamics

Journal of Aircraft, 1981
A new frequency parameter that minimizes the number of points required to represent unsteady aerodynamics has been developed. The parameter expands the low range of the reduced frequencies where the aerodynamics vary rapidly and compresses the moderate to high frequency range into a finite domain.

Unsteady Aerodynamic Modeling

2015
This chapter details the various methods of deriving an unsteady aerodynamic model for aeroservoelastic analysis. This usually takes the form of a linear operational relationship between pressure distribution and upwash distribution on a lifting surface for subsonic and supersonic flows, and a nonlinear partial differential equation (Euler, full ...

Unsteady Aerodynamic Methods

1993
This paper reviews recent advances in the theoretical and computational modeling of turbomachinery unsteady flows. In particular, the unsteady aerodynamic analyses intended for aeroelastic and aeroacoustic predictions must be applicable over wide ranges of operating conditions and modes of unsteady excitation.

Unsteady Three-Dimensional Turbine Aerodynamics

Journal of Engineering for Power, 1982
High response aerodynamic measurements were made in a large-scale, axial, flow turbine model to study the unsteadiness and three dimensionality of the flow. High response velocity vector and total pressure data were acquired. A comparison was made of the results of phase lock averaging both raw and reduced data (voltages and velocities).
