DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

[0036] This invention relates to compact and lightweight drone delivery device called an ArcSpear Electric Jet Drone System having an electric ducted air propulsion system and being relatively difficult to track in flight. The invention relates generally to aircrafts, and more specifically, to an unmanned aerial vehicle (UAV) system and method of use. The present application relates to the field of unmanned aerial vehicle control technology, particularly, to an unmanned drone device capable of delivering payloads which can be secured to the device and has controllable flight powered by electrically powered ducted air as a propulsion arrangement. The invention relates generally to defense systems, and more specifically to an unmanned aerial vehicle with a weapons deployment or munitions carrier such as a grenade launcher.

[0037] The advantages and related characteristics for a compact and lightweight drone delivery device called an ArcSpear Electric Jet Drone System 30 are listed above in the introduction. Succinctly the benefits are that the device: [0038] A. Is lighter weight due to lighter electric motors than gas-powered systems and lightweight, carbon fiber frame (is 5 to 15 pounds and less than 1? cubic feet); [0039] B. Uses no combustible fueluses rechargeable batteries; [0040] C. Is quiet, no combustion noise, stealth; [0041] D. Is unmanned operation with remote controlled operation and Simple, servo-controller-based throttle to control Electronic Speed Controllers (ESCs) which drive electric motors; [0042] E. Capable of speed of up to 180 miles-per-hour {MPH}; [0043] F. Is a multi-copter with ducted fans, ducted turbines with protected intakes and more than one ducted fan/turbine arrayed with counter-rotating propellers/turbines; [0044] G. Has a small cross-section to deflect tracking signals and search beams. With such a small cross section and such a high speed, it would be able to fly low and between buildings and trees, making it nearly impossible to shoot down, unlike slower, comparable payload carrying drones that fly at less than 60 mph and have large propellers; [0045] H. Capable of rapid setup for launch and rapid start (no pull-starting, priming, or other pre-start actions needed to start the motor); [0046] I. Carries payloads of up to 20 pounds payload per 10 of total aircraft weight (typical ArcSpear is 5 to 15 pounds and less than 1? cubic feet); [0047] J. Operates with smooth, low-vibration operation; [0048] K. Uses commonly available drone stability using multiple gyroscopes with a standard multi-copter flight controller; [0049] L. Is relatively inexpensive so that it could be reused OR used just once, depending on mission requirements; [0050] M. Is safe to operate around with its ducted turbine blades; [0051] N. Can be used as a poor man's Javelin missile, flying at long distances (over 20 miles is possible) at high speed, then finding its target would shoot or drop its munitions on target; [0052] O. Controls allow automatically return home; [0053] P. Can be re-fitted with payloads for re-use; [0054] Q. Can be used effectively as a military asset, capable of deploying munitions against targets in a manner that allows for extreme control in congested urban, forested, or other confined environments, at high speed, with a cross-section and speed that would make it extremely difficult to shoot down; and [0055] R. Utilizes electric jet turbine engines with 10:1 or greater thrust to weight ratio, such that for every one pound of engine plus ESC combined weight, the entire assembly produces at least 10 pounds of thrust. This would not include battery weight.

FIGS. 4 D and E depict a connection of a harness 105 to several clusters of the ArcSpear Electric Jet Drone System 30. ArcSpear can be used for personal, human transportation in swarms that connect to specially crafted harnesses with frames that allow multiple 4, 6, 8 or more-engined ArcSpears to link together on a harness-mounted frame, and lift an individual into the air, as a single, controllable, on-demand, personal Jetpack or other configuration, including that of something resembling a flying car that could carry more than one person. It is effectively utilizing the unexposed nature of ArcSpear's Propulsion to closely couple swarms of them to provide effective, human transport. Many drone swarms are used today in light shows and other displays, but they must maintain several body lengths of distance from each other because most are open-propeller driven. Because ArcSpear encapsulates its propulsion, swarming can allow close coupling of multiple 6 aircraft together to provide clustered Propulsion for human or even heavy payload transport.

[0068] The anticipated materials for the compact and lightweight drone delivery device 30 called an ArcSpear Electric Jet Drone System include: a group of fabric material for the flexible belt 146 can be nylon, rayon, cotton, polyester, leathers, vinyl, and synthetic or non-synthetic composite materials. The characteristics preferred are a fabric which is flexible, comfortable, strong, cut-resistant, lightweight, and easy to clean. The method to attach the belt and harnesses to the frame 71 or to each other may be sewing, clips, rivets, or various fasteners. The propellers 51 may be a metal such as steel, steel alloy, aluminum, titanium; a composite material; a wood laminate, or other durable, light weight yet sufficiently sturdy material. Propellers are well known in the art of aircraft and may be selected from a plethora of styles and materials. The other components are likewise expected to be of lightweight, strong, and durable materials shaped to appropriate configurations. However, these are exemplary and lot limitations to other means which are well within the spirit and scope of the full embodiment of the compact and lightweight drone delivery device 30 called an ArcSpear Electric Jet Drone System. The entire propeller driven system, as just described, rotates around the fixed shaft which can have an aperture (hollow opening) throughout its center. The various control wiring is often guided along and through the structure as is well known in the art of lightweight aircraft. Additionally, a mount for the motor (s) 78 are normally retained by a collar to the shaft. The battery (ies) 74 are connected through cables and wire harnesses to the motor (s). The electric power from the battery powers the motor which transforms the stored electrical energy into kinetic energy and rotational power. This power is further transferred to the propellers and the system shown or a functional equivalent. The motors 78 have relatively simple Electric Speed Controllers (ESC) and controls 90 as one skilled in the art of electromechanical power systems well appreciates. The remote-control system and controller 95 for operation of the drone can be one of many well-known to the drone industry and aircraft operations. These are used in combination with readily available 3-D goggles 92 of operator 100 with signals to/from camera 82. As stated, this means of using a remote system is also well known to those skilled in the art of electrical and electronic remote-control systems. The remaining shrouds and mechanical structures can be of various materialssteel, steel alloys, titanium, aluminum, and composite metals, etc. The general components were identified above.

[0069] The frame structures 71, 71A may be of a variety of configurations but the preferred is a flat plate-like shape. The materials for example and not limitation may be a metal like steel, a steel alloy, aluminum, titanium, a composite plastic, plastic filled with carbon fibers, or any other light weight, durable material. However, these materials mentioned are exemplary and lot limitations to other means which are well within the spirit and scope of the full embodiment of the device 30. The batteries 74 are connected generally through cables and harnesses and generally to a central battery block then through the ESCs 80 and to the motor (s) 78. The electric power from the battery powers the motor which transforms the stored electrical energy into kinetic energy and rotational power. This power is further transferred to the propellers and the system shown or a functional equivalent. The motors 78 and battery 74 system have relatively simple electronic speed controllers (ESC) 90 flight controllers 80 as one skilled in the art of electromechanical power systems well appreciates.

[0070] This system anticipates several types of rechargeable battery 74 back including but not limited to: Nickle Cadmium batteries, Nickle Metal Hydride batteries, Lithium-Ion batteries, Small and sealed lead acid batteries. These may be Absorbed glass mat (AGM) battery or gel battery (gel cell). Other experimental types include Lithium sulfur, Sodium-ion, Thin film lithium, Zinc-bromide, Zinc-cerium, Vanadium redox, Sodium-sulfur, Molten salt, and Silver-zinc. One skilled in the art of rechargeable batteries also anticipates and fully expects other battery types to be developed which will function well and be within the scope and breadth of this invention. Voltages of the system may also vary.

[0072] The compact and lightweight drone delivery device 30 called an ArcSpear Electric Jet Drone System having an electric ducted air propulsion system and being relatively difficult to track in flight has been described in the above embodiment. The manner of how the device operates is described below. One notes well that the description above and the operation described here must be taken together to fully illustrate the concept of the compact and lightweight drone delivery device called an ArcSpear Electric Jet Drone System. The preferred embodiment of the compact and lightweight drone delivery device 30 called an ArcSpear Electric Jet Drone System comprised of: (a) a frame system 71; (b) a ducted turbine system comprising at least one and preferably four turbine 50 with a set of blades or impellers 51 of the fan/turbine 50, a shroud/exterior protection and frame 55 of the turbine/fan 50, a cut protector 55A on shroud 55, a means 56 to secure shroud 55, and an electric motor 78 with each fan 50 the device 30 with shaft 58 connected to blades 51; (c) a payload 110 with a deployment means 115 on the structural frame 71; (d) a power system comprising a set of rechargeable batteries 74, a means to removably secure the batteries 74 to the frame 71, a wiring harness from batteries 74 to motors 78, a recharge plug 79 to batteries 74 from recharging power source 89, and a recharging power source 89; and (e) a flight controller 80 for powering the ESC 90 and controlling the motor 78 plus a set of connectors 85 from the set of batteries 74 to the motor 78 wherein the device 30 having an electric ducted air propulsion system, being relatively difficult to track in flight (stealth), being relatively fast, able to maneuver quickly and able to refuse the device to repeat and carry payloads after recharging and replenishing the payload.

[0073] The compact and lightweight drone delivery device 30 called an ArcSpear Electric Jet Drone System functions as follows: The electric fans and motors devices 50, 78 are compact, lightweight and may be ducted with carbon-fiber or other lightweight material ducts. Motors are connected to electronic speed controllers and powered by the batteries and then managed through a throttle 80, which is managed by a user/operator 100 through the controller 95 which are connected and control the flight controller 80. The operator 100 monitors visually through the goggles 92 that are connected by antenna 81 to the camera 82. The power from the batteries 74 are controlled by the flight controller 80 and operate the ESC 90 to each of the motors 78 and coupled ducted fans 50 to balance thrust to each fan 50 and thus control the speed and thrust of each fan motor 78 and limits roll from side to side. By increasing and decreasing the fan motors speed by controlling the electrical power, the thrust of each fan is controlled and the drone 30 can be moved and guided by the resultant thrust of each fan. The drone 30 is guided to a target 150 by the operator 100 and then the payload 110 is activated/dropped/deployed by the payload controller 115 activated by the operator 100 on the controller 95.
