Aerodynamic forces on high speed multi-hulled marine vehicles [PDF]
The need for high-speed high-payload craft has led to a considerable interest in vehicles capable of bridging the gap between conventional ships and aircraft. One such concept uses the forward motion of the craft to create aerodynamic forces on a wing-

The Effects of Aerodynamic Interference on the Aerodynamic Characteristics of a Twin-Box Girder
To investigate the aerodynamic characteristics of a twin-box girder in turbulent incoming flow, we carried out wind tunnel tests, including two aerodynamic interferences: leading body-height grid, and leading circular cylinder.

In vivorecording of aerodynamic force with an aerodynamic force platform: from drones to birds [PDF]
Flapping wings enable flying animals and biomimetic robots to generate elevated aerodynamic forces. Measurements that demonstrate this capability are based on experiments with tethered robots and animals, and indirect force calculations based on measured kinematics or airflow during free flight.

Estimation of Airship Aerodynamic Forces and Torques Using Extended Kalman Filter
An airship is a lighter than air, aerial vehicle whose model is based on dynamic, aerodynamic, aerostatic and propulsion forces and torques. Apart from other, aerodynamic forces and toques are difficult to measure.

Effect of cross wind on aerodynamic coefficients of ground vehicles. [PDF]
The present work investigates the variation of aerodynamic coefficients with the change in the angle of flow. A mathematical equation has been developed for predicting the aerodynamic coefficients, when a vehicle is subjected to crosswind.

The aerodynamic force platform as an ergometer
Animal flight requires aerodynamic power, which is challenging to determine accurately in vivo. Existing methods rely on approximate calculations based on wake flow field measurements, inverse dynamics approaches, or invasive muscle physiological recordings. In contrast, the external mechanical work required for terrestrial locomotion can be determined

Spacecraft Flight in the Atmosphere [PDF]
Spacecraft that orbit in Low Earth Orbit travel through a tenuous atmosphere and hence experience aerodynamic forces that can become quite significant, specially at low altitudes. The presence of these forces can become a major design driver for missions
