Abstract:
A system for landing UAV's comprising a slingshot structure (25) that includes a central arm (26) and an axis means (45) installed along the central arm of the structure and wherein it enables the central arm to move around it in addition, the system comprises base means (50) connecting the axis means to a platform (20) at which the system is installable. The system also include a controlled pulling and braking means (55) that connects between lower end of the central arm of the structure and the platform upon which the system is installable and an assembly (35), essentially formed as a substantially "Y" shape part that is installable unto the top end of the central arm of the structure and a stretchable elastic means (30) installed in a stretched manner at a gap formed between the two arms of the assembly and set to connect with a landing UAV(15). At the landing phase, the controlled pulling and braking means of the system, essentially brakes the motion of the central arm of the structure that is propelled to revolve around the system's axis means, from a time that the UAV forms contact with the elastic means and with it propels the structure to move around the axis means.

Abstract:
A flyer assembly (10) is adapted for launching with, transit in, and deployment from an artillery shell (22). The flyer assembly (10) includes a jettisonable shroud (12) and a flyer (14). The flyer (14) is adapted to withstand a launch acceleration force along a flyer axis when in a first state, and to effect aerodynamic flight when in a second state. When in the first state, the flyer (14) is positionable within the shroud (12) with the flyer axis parallel to the shroud axis and the shell axis. The flyer (14) includes a body member disposed about the flyer axis, and a foldable wing assembly (20) mounted to the body member. THe wing assembly (20) is characterized by a plurality of nested wing segments (32) when the flyer is in the first state. THe wing assembly (20) is configurable in an unfolded state characterized by a substantially uninterrupted aerodynamic surface when the flyer is in the second state. The flyer assembly (10) is launched from an artillery cannon, and can thus reach a target quickly, without expending energy stored with theflyer. During launch, the flwyer is coupled to the shroud so as to maintain a portion of the flyer in tension during an acceleration of the flyer along eht flyer axis.
Abstract:
A flyer assembly is adapted for launching with, transit in, and deployment from an artillery shell having a central void region extending along a ballistic shell axis. The flyer assembly includes a jettisonable shroud and a flyer. The shroud extends along a shroud axis, and is positionable within the central void region with the shroud axis substantially parallel to the shell axis. The flyer is adapted to withstand a launch acceleration force along a flyer axis when in a first state, and to effect aerodynamic flight when in a second state. When in the first state, the flyer is positionable within the shroud with the flyer axis parallel to the shroud axis and the shell axis. The flyer includes a body member disposed about the flyer axis, and a foldable wing assembly mounted to the body member. The wing assembly is configurable in a folded state characterized by a plurality of nested wing segments when the flyer is in the first state. The wing assembly is configurable in an unfolded state characterized by a substantially uninterrupted aerodynamic surface when the flyer is in the second state. The flyer assembly is adapted to be launched from a ballistic delivery system such as an artillery cannon, and can thus reach a target quickly, without expending system energy stored within the flyer. During launch, the flyer is coupled to the shroud so as to maintain a portion of the flyer in tension during an acceleration of the flyer along the flyer axis resulting from the launch. The flyer assembly is adapted to withstand the high g-load an high temperature environments of a cannon launch, and can tolerate a set-back g load of about 16,000 g.

Abstract:
An unmanned aerial vehicle (UAV) platform includes a stationary base constructed and arranged to reside over a fixed location on a surface (e.g., a ground location, a ship's deck, a trailer or other vehicle, etc.). The UAV platform further includes a set of UAV interfaces constructed and arranged to interface directly with a UAV (e.g., a launcher, a net apparatus, etc.). The UAV platform further includes a turntable assembly which couples to the stationary base. The turntable assembly is constructed and arranged to couple to each UAV interface and control angular direction of that UAV interface over the fixed location. A method of operating a UAV platform includes deploying the UAV platform over a fixed location, preparing a UAV interface on a turntable assembly of the UAV platform, and rotating the turntable to control angular direction of the UAV interface over the fixed location.
