This is an example simulation extension plugin for OpenRocket. It defines a simulation extension that multiplies the motor thrust by a provided value.

Compile by running ant. This creates the file MultiLevelWind.jar. Copy this to the OpenRocket plugin directory (~/.openrocket/Plugins/ on Linux, ~/Library/Application Support/OpenRocket/Plugins/ on Mac, ...\Application Data\OpenRocket\ThrustCurves\Plugins\ on Windows). Then restart OpenRocket.

You can add and configure it in the simulation edit dialog under Simulation options -> Add extension -> Flight -> MultiLevelWind
