A CFD-informed quasi-steady model of flapping-wing aerodynamics [PDF]

open access: yes, 2015
Aerodynamic performance and agility during flapping flight are determined by the combination of wing shape and kinematics. The degree of morphological and kinematic optimization is unknown and depends upon a large parameter space.

Efficient computation of aerodynamic influence coefficients for aeroelastic analysis on a transputer network [PDF]

open access: yes
Aeroelastic analysis is multi-disciplinary and computationally expensive. Hence, it can greatly benefit from parallel processing. As part of an effort to develop an aeroelastic capability on a distributed memory transputer network, a parallel algorithm ...

The planar dynamics of airships [PDF]

open access: yes, 1975
The forces and moments acting upon a LTA vehicle are considered in order to develop parameters describing planar motion. Similar expressions for HTA vehicles will be given to emphasize the greater complexity of aerodynamic effects when buoyancy effects ...

Formulation of the linear model from the nonlinear simulation for the F18 HARV [PDF]

open access: yes
The F-18 HARV is a modified F-18 Aircraft which is capable of flying in the post-stall regime in order to achieve superagility. The onset of aerodynamic stall, and continued into the post-stall region, is characterized by nonlinearities in the ...

Flight-Measured Aerodynamic Loads on a 0.92 Aspect Ratio Lifting Surface [PDF]

open access: yes
Ventral fin loads, expressed as normal force coefficients, bending moment coefficients, and torque coefficients, were measured during flight tests of a YF-12A airplane.

Numerical simulation of rivulet evolution on a horizontal cable subject to an external aerodynamic field [PDF]

open access: yes, 2010
On wet and windy days, the inclined cables of cable-stayed bridges may experience a large amplitude oscillation known as rain-wind-induced vibration (RWIV).
