Abstract: An aerial vehicle securing system for use with a base portion of an aerial vehicle, comprising: at least one substantially flat platform for supporting said base portion upon landing of the vehicle thereon; at least one magnetizable element configured to be integrated in one of said platform or base portion; at least one electropermanent magnet configured to be integrated in another one of said platform or base portion, said electropermanent magnet configured for generating a magnetic field, so that upon a distance between said base portion and said platform reaching a pre-determined value during the landing of the vehicle on the platform, said magnetic field is configured to cause magnetizable element to be attracted to at least said one electropermanent magnet; and a power supply module configured for generating an electric current to said at least one electropermanent magnet for selectively generating and cancelling said magnetic field.

Abstract: An add-on brake system includes a housing accommodating a linear actuator including: an electric motor having a rotor and a stator; a nut arrangement coupled to the rotor; a linear threaded plunger associated having a first end linearly protruding from one end of the arrangement and a second end linearly protruding from an opposite end thereof; an inboard brake pad coupled to the housing; and an outboard brake pad associated with the second end, oriented transverse to the plunger. The plunger has an initial unclamped position in which the second end protrudes to an extent n1 from the other end of the arrangement, yielding a spacing S1 between the inboard and outboard brake pads, and a final clamped position in which the second end protrudes to an extent n2>n1 from the other end of the arrangement, yielding a spacing S2
