Possible bug in paparazzi center? SOLVED

Chris Efstathiou
Hi Gautier !

I found the problem, it was the launcher command line ie.
/home/hendrix/paparazzi/./paparazzi

It wanted the command without "./"

Btw is there any support for transitional flight in the paparazzi code?

I am thinking that a delta wing with two counter rotating blades and
wing supports would be able to take off vertically and transition to
level flight with minimum effort.

I am thinking of mounting the IMU to a servo and rotating it 90 degrees
according to what flight stage the aircraft is in and of course change
autopilot ailerons with the two motor throttles and autopilot yaw with
the airplane ailerons while vertical.

Chris

Hi Chris,

Would not be easier to multiply the output of the IMU by a rotation matrix? In fact, I do not know whether is possible to change in flight the values of the "mounting imu".

Hi Chris,

Mounting the IMU on a servo may be fun, but it is not necessary. When the plane transitions, the attitude feedback will still work as normal, since the actuators will still do the same w.r.t. the body axes. You may use AP_MODE_FORWARD to transition to forward flight if you want to fly RC with attitude control. The control effectiveness of the flaps will become higher as the plane goes into forward flight, which can be dealt with by using the gain scheduling module.

You can also use INDI to control the attitude, with the control effectiveness scheduling module. That is what we developed to fly the Cyclone:
