AeroToy 0.1 beta

AeroToy two-way fluid-rigid-body real-time simulator

Version 0.1 beta

This is the first release of AeroToy, an interactive fluid simulator featuring two-way interaction between a semi-lagrangian real-time fluid simulation and a 2D rigid body physics simulation.

Installation

Currently only a Windows binary build is available. Source code is not currently public.
No installation is necessary, download aerotoy.zip, extract the whole directory, and run aerotoy.exe.

Features

Craft Editor

• Real-time fluid simulation during edit, providing real-time feedback
• Bezier wing editor
• Freehand wing paint tool
• Composition of rigid-body nodes from part nodes including Bezier curves and preconfigured parts such as engines
• 4 simulation viewing modes:
  • Smoke (with configurable colour patterns)
  • Velocity
  • Pressure
  • Isobars
• Aerodynamic force vector and L/D annotation
• Preconfigured parts:
  • Bezier curve wings
  • PNG image file based wings
  • Pivot joint
  • Servo joint (controllable during test flight)
  • Wheels
  • Ballast

Flight Testing

• Aircraft control:
  • WASD = control engine throttle (W,S) and servo joint pitch (A,D)
  • Shift = double servo joint movement
  • Q,E = control joint pitch "trim" - replicating aircraft elevator trim
• YAML defined test environments
  • User environments can be added by adding new definition files
  • Environment repeats providing infinite test flight area
• Configurable wind speed
• Selectable airflow visualization tools:
  • Smoke ring - A striped smoke pattern emitted in a semi-circular shape ahead of the moving aircraft
  • Craft Smoke - Smoke emitted from the surface of the aircraft
• Avionics Window featuring:
  • Airspeed
  • Elevation
  • Flight duration
  • Max flight duration
  • Current throttle
  • Current trim
• Testing of fixed machines, such as windmills or kites, is also supported
