Arduplane Maximum Ground Speed

Is there any maximum operating ground speed for the Arduplane?I know that the GPS is designed in such a way that it disables itself as soon as it crosses 500 m/s but I want to know if there are any…Continue

Control of Rudderless Aircraft

We are working on an aircraft that operates solely by thrust vectoring and has no conventional control surfaces. To simplify the design and control, we are going for a rudder-free design.I wanted to ask if APM 2.5 can be used to fly an aircraft without a rudder in auto mode.Will making the aileron-rudder mixing parameter 0 work?ThanksSee More

Arduplane Maximum Ground Speed

Is there any maximum operating ground speed for the Arduplane?I know that the GPS is designed in such a way that it disables itself as soon as it crosses 500 m/s but I want to know if there are any operational limits due to the IMU or the processor which restrict the maximum velocity of a fixed wing aircraft.See More

Hi Bharat,

The latest version of MatrixPilot computes ground speed, wind speed, and air speed for a fixed wing aircraft without an airspeed sensor as follows:

1. Wind speed estimate is revised each time the plane changes direction, using the approach described here, which uses the turn to compute airspeed during the turn, and then computes windspeed from ground speed.

2. All of the time there is an accurate estimate of the ground speed vector by fusing the GPS, gyro, and accelerometer signals.

3. All of the time the airspeed vector is computed from the wind speed vector and ground speed vector.

So, the key is to compute the wind speed without winding up in a circular dependency of the computations.

Best regards,

Bill
