Overview

The TARG parameter group (specifically TARG_SP) configures the target setpoints for specialized navigation modes.

Key Concepts

1. Autorotation Glide Speed

  • TARG_SP: Defines the target ground speed (cm/s) for the helicopter autorotation controller to maintain during the glide phase.

Developer Notes

  • Library: libraries/AC_Autorotation.

TARG_SP

cm/s
Default 1500
Range 800 2000

Target Glide Ground Speed (TARG_SP)

Description

This parameter sets the target ground speed for the autonomous autorotation controller during the glide phase. Maintaining the correct forward speed is critical for keeping the rotor RPM in the green arc and reaching the designated landing spot during an engine failure scenario.

The Mathematics

PID Setpoint.

The Engineer's View

Defined in libraries/AC_Autorotation/AC_Autorotation.cpp.

Tuning & Behavior

  • Default Value: 1500 cm/s (15 m/s)
  • Tuning: Adjust based on the specific best-glide speed of your helicopter.
