Adaptive control: wing drop and engine failure


Video showing a Multiplex Twinstar II running the Paparazzi adaptive control loops. It drops 30% of the right wing with 50% of the aileron, turns off the right motor and keeps flying autonomously.

Really cool :-) can this be adapted to the APM. Without going to such extreme UAV reconfiguration in flight this can be very handy when one has to fly a payload which will change over the course of the flight

Wait.. really? You did this on purpose? Tell you you are joking.

that is one impressive bit of software coding you have done there. It has taken major companies years to produce something like this and no you have made it available for home builders. Good work. Now I just need to see if I can get it and fit it to my twin engine aircraft for that "just in case" moment

Any chance of APM getting access to the source code to complete this.

Very cool, congrats!

The adaptive control loop is not the standard setup for a Paparazzi fixed wing aircraft. It is in proof of concept state and it will need some more work to be flown on a day-by-day basis. Other aircraft types will have to be tuned individually.

It is not limited to the "wing drop", though. There was an unscheduled challenge of the adaptive control during the development/test flights at ENAC in Toulouse. We flew at a regular RC field with other manually controlled RC aircrafts in the air. We did not notice the severity of a mid-air collision with a glass-fiber aircraft until we had landed.
