Centripetal force compensation is a algorithm than compensate centripetal forces effect over accelerometers so AHRS could get a correct attitude measurement during large turns.we are using a simple record player to test centripetal compensation.Effect of centripetal force could be a problem if the plane stay in a turn for a large time, for example doing circles.jlcortexnmine.com

    Love it, well done. Almost a flat spin simulator.

    Hey Jose,
    I was assuming a 33.3 RPM turntable. Yes, a 45RPM turntable should give about a 16 deg error. Science is wonderful!

  • Brian, yes, the experiment is only to see the compensation working.
  • Brian, it is not a G-Force test!!!

    it is a test to verify centripetal force compensation. with this experiment (radius = 0.13 meter and rpm = 45) we get a error of 16 degree without compensation, it is perfect to test it!

    I just punched in the numbers, and a .18G lateral acceleration should integrate up to about a 10 deg. roll error. The time it takes to integrate up depends on how well the compensation is working.

    If you use the old Accel = radius*w^2 equation I come up with only 0.18 G's of lateral acceleration. I don't think that will be enough to do much of a test with the record player. A 0.2G turn is pretty benign.
    If you could speed up the record player or get a larger radius then you might get something more indicative of a turn rate your aircraft would experience. Problem is the motor in the record player might complain. I guess if you ran it for a really long time an error might integrate up.
  • Hi Joseph,

    yes, firstly we have tested it in a car, but we can not see nothing. it is a good method. it is very easy to see if compensation is working!
  • Cool idea, how did the attitude estimation hold up?
