Detailed Description

Pneumatic launcher system See video of the system: https://www.youtube.com/watch?v=qc1uwH-8Dbw Launcher.

A pneumatic launching system.

  • Phase 1: Zero Roll, Takeoff Pitch, Full Throttle(once you enter the block!)
  • Phase 2: After detecting lauch (ground speed) and travelling enough distance from the launch point follow launch line -> Auto roll, Takeoff pitch, Full Throttle
  • Phase 3: If the aircraft is above a specific alt, greater than a specific speed or too far away, circle up with takeoff circle radius, until you reach desired takeoff altitude

An example section to be added into your airframe configuration:

<section name="LAUNCHER" prefix="LAUNCHER_TAKEOFF_"> <define name="PITCH" value="0.23" unit="rad"> <define name="HEIGH" value="70" unit="m"> <define name="MIN_SPEED_CIRCLE" value="8" unit="m/s"> <define name="DISTANCE" value="30" unit="m"> <define name="MIN_SPEED_LINE" value="5" unit="m/s"> </section>
