Demos | Aerodynamic Objects

The AO package includes a wide range of demo scenes in Unity to highlight example use cases

Source code for all vehicle models shown are included in the AO package

Web playable demos from AOv1(2023)

A simple lighter-than-air balloon attached to a ballast weight with a simple string model. The balloon has an aerodynamic model with Buoyancy and Drag components. The balloon has a custom BallloonController script running on it that allows the user to inflate or deflate the balloon and hence change the buoyancy force. The user can also change the wind speed and change the length of the string during the game.

Vertical Wind Tunnel

Drop rag doll skydivers and random shaped objects into a vertical wind tunnel. Change the wind speed and see what happens. Wind tunnel is built using a custom Fluid Zone that produces a local vertical wind that drops off with height. Objects are randomised in terms of shape and centre of mass location. Skydivers are built using a mannequin asset from Bevans Media.

Wind turbine

A simple wind turbine made from three Aerodynamic Object blades and tail fin with Lift and Drag components. The rotor and tail fin assembly is free to rotate around the mast so that it naturally points into the wind. The user can vary the aspect ratio of the blades and blade pitch angle as well as the wind speed and direction. The turbine has a simple generator model that outputs power proportional to aerodynamic torque and rotation rate. The brightness of the light is proportional to the power generated. How much green energy can you make?

Flight Vehicle Showcase

Try out a hang glider, transport aircraft, helicopter, airship, Wright Flyer or quadcopter built using Aerodynamic Objects. The source code for all these models is provided as part of the AO package

Custom Flow Primitive

An example of using flow primitives to model the ideal flow around a spinning cylinder. The model uses a uniform flow, plus source, sink and vortex elements. The user can vary the wind speed, the spin rate of the cylinder and the size of the cylinder.

Ensemble demo

A number of different AO models all running in the same Unity scene. This demonstrates flexibility of use and the low implementation overhead for aerodynamic models. There are no user inputs in this demo.
