Auto-injector countermeasure for unmanned aerial vehicles

A method of non-destructively disabling and controlling a threat unmanned aerial vehicle (UAV) comprising the steps of:

• controlling a predatory UAV to intercept the threat UAV;
• controllably aligning a rigid housing extending from a body of the predatory UAV and containing a penetrator rod, with a target area of the threat UAV;
• firing said penetrator rod from said rigid housing to pierce the surface of the threat UAV at the target area and lodge within the target area of the threat UAV, in response to a trigger signal;
• injecting a disabling substance to the interior of the target area of the threat UAV via said penetrator rod lodged there within, wherein the disabling substance disables flight control of the threat UAV;
• exerting flight control over the threat UAV, via said predatory AUV;
• and
• navigating said threat UAV to a given location for retrieval.

An auto-injector device for use with a predatory unmanned aerial vehicle (UAV) to non destructively disable and control a threat UAV, comprising:

• a penetrator rod having a hollow core and an orifice proximal to a point of said penetrator rod, configured to pierce a fuselage of the threat UAV;
• a cylindrical body having an open end, configured to hold said penetrator rod;
• a pressurized volume of a disabling fluid, coupled to said hollow core of said penetrator rod and configured for conveyance through the penetrator rod to the orifice for delivery to the fuselage of the threat UAV;
• a propulsion mechanism for propelling said penetrator rod out from said cylindrical body via said open end upon receiving a deployment signal;
• and
• a controllable mount for attaching said auto-injector device to the predatory UAV configured to control an angle of approach of said auto-injector device relative to the predatory UAV as the predatory UAV closes on the threat UAV.
