Abstract:
1. A parachute release device comprising: a triangular connecting element capable of connecting between an Unmanned Aerial Vehicle (UAV) and a parachute; a locking mechanism capable of releasing said triangular connecting element from said UAV upon being actuated; and an actuator to (a) actuate said locking mechanism upon touchdown of the UAV with a ground, and (b) cause disconnection of the triangular connecting element from the UAV upon touchdown of the UAV with the ground; wherein said locking mechanism is adapted to inhibit a force from being applied to said actuator; wherein the triangular connecting element is an isosceles triangle and comprises (A) a first, undercut shaped, base edge having a locking angle relative to a lower surface of the triangular connecting element, and (B) two other side edges shaped in draft angles relative to the lower surface of the triangular connecting element; wherein, when the triangular connecting element is actuated to be connected to the UAV, the first edge and the two other edges are to hold the triangular connecting element within a recessed cavity of the UAV; wherein, when the triangular connecting element is being disconnected from the UAV, the first edge and the two other edges are to disconnect from the recessed cavity of the UAV in any direction, when being pulled by the connected parachute, and to disconnect between the parachute and the UAV in any angle of the parachute relative to the UAV.
