Abstract
A 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.
Claims19
A 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 landing disc assembly comprises a connection element and a disc carrier assembly,
- wherein the connection element comprises:
- an upper connection element comprising an inner bushing configured to connect to the shock absorber and an outer bushing, wherein the inner bushing is insertable into the outer bushing,
- a lower connection element fastened to the disc carrier assembly, and
- a spherical joint connecting the upper connection element and the lower connection element, and
- wherein the switch is configured to indicate a landing or a taking-off of an aerial vehicle from the ground surface.
6 more elements
A landing gear for an aerial vehicle, the landing gear comprising:
- a landing gear shock absorber;
- and
- a system mounted to the landing gear shock absorber, the 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,
- wherein the system comprises:
- a sensor assembly comprising the switch, and
- a landing disc assembly comprising a landing disc carrier,
- wherein the landing disc assembly is configured to activate the switch,
- wherein the sensor assembly is fastened to a shock absorber fixed element of the landing gear shock absorber,
- wherein the landing disc assembly is fastened to a shock absorber rotatable element of the landing gear shock absorber, and
- wherein the sensor assembly is rotatably connected to the landing disc assembly.
