Abstract
In an embodiment a weight on wheels (WOW) system for a landing gear system includes a sensor assembly with a switch and configured to be mounted to a shock absorber, and a landing disc assembly connected to the sensor assembly, the landing disc assembly configured to contact a ground surface and to be mounted to the shock absorber, wherein the switch is configured to indicate a landing or a taking-off of an aerial vehicle from the ground surface.
Claims20
A weight on wheels (WOW) system for a landing gear system, the WOW system comprising:
- a sensor assembly comprising a switch and configured to be mounted to a shock absorber;
- and
- a landing disc assembly connected to the sensor assembly, the landing disc assembly configured to contact a ground surface and to be mounted to the shock absorber,
- wherein the switch is configured to indicate a landing or a taking-off of an aerial vehicle from the ground surface.
A landing gear for an aerial vehicle, the landing gear comprising:
- a landing gear shock absorber;
- and
- a weight on wheel (WOW) system mounted to the landing gear shock absorber, the WOW system configured to:
- activate a switch by forces occurring when the aerial vehicle touches a ground surface, wherein the switch is activated when the forces pass a threshold of 75 N;
- and
- provide feedback to a flight control system of the aerial vehicle when the forces pass the threshold.
A method for operating a take-off-and-landing-gear of an aerial vehicle, wherein the take-off-and-landing-gear comprises a landing disc assembly and a sensor assembly comprising a switch, the method comprising:
- touching, by a disc carrier of the landing disc assembly, a ground surface of a terrain during a landing phase;
- and
- activating, by a switch activation element of the landing disc assembly, the switch arranged at the sensor assembly by moving the switch and the switch activation element in a vertical/axial direction towards each other.
A method for operating a take-off-and-landing-gear of an aerial vehicle, wherein the take-off-and-landing-gear comprises a landing disc assembly and a sensor assembly comprising a switch, the method comprising:
- taking-off, by a disc carrier of the landing disc assembly, from a ground surface of a terrain during a take-off phase;
- and
- de-activating, by a switch activation element of the landing disc assembly, the switch arranged at the sensor assembly by moving the switch and the switch activation element in a vertical/axial direction away from each other.
