Abstract

ordnance for air-borne delivery to a target under remotely controlled in-flight navigation. In one embodiment, self-powered aerial ordnance includes upper and lower cases. A plurality of co-axial, deployable blades is powered by a motor positioned in the upper case. When deployed, the blades are rotatable about the upper case to impart thrust and bring the vehicle to a first altitude above a target position. An explosive material and a camera are positioned in a lower case which is attached to the upper case. The camera generates a view along the ground plane and above the target when the ordinance is in flight. When the vehicle is deployed it is remotely controllable to deliver the vehicle to the target to detonate the explosive at the target. The ordnance may drop directly on a target as a bomb does.

Claims (19)

WE CLAIM:
1. A method of delivering an explosive ordnance from a first altitude to a destination on or above a ground plane and avoiding collateral damage, the method including: a. providing an ordnance comprising: a tubular shaped body having first and second opposing end portions and an explosive component positioned therein; a plurality of blades connected to the body at or near the first end portion for rotation about the body under powered operation to impart thrust and bring the ordnance to a first altitude above a target position; a motor positioned within the tubular shaped body, connected to selectively provide the powered operation to impart the thrust and thereby provide propulsive lift to the ordnance via the blade rotation; an imaging device mounted along the second end portion to generate frames of image data representative of a view of a ground plane while the ordnance is airborne, where the imaging device acquires infrared or visible light images; first receiver circuitry configured to receive radio frequency (rf) control signals and coupled to effect operation of other components of the ordnance in response to the received signals; rf video transmission circuitry coupled to receive the frames of image data and transmit rf signals comprising a stream of the image data; b. providing a user controllable remote control device, positionable remote from the ordnance, the remote control device including circuitry comprising a combination of: (i) rf control circuitry that, responsive to user input, transmits control signals for a person to direct operation of the ordnance when flying and hovering; (ii) rf receiver circuitry for receiving the stream of image data; and (iii) video processing circuitry that receives the image data from the rf receiver circuitry and displays image data from the stream of image data for display on a screen wherein: when the ordnance is airborne above a ground plane, (i) the blades are positioned above the motor and are connected to the motor via a shaft for rotation about a central axis, and 42877007_1 (ii) the imaging device can generate frames of image data representative of a view of a portion of the ground plane directly below the ordnance, and after the powered operation is initiated to impart the propulsive lift to the ordnance, frames of image data, representative of a view of a portion of the ground plane vertically below the ordnance, can be generated based on image data acquired with the imaging device positioned on the ordnance, and one or more first control signals can be sent from the remote control device to navigate movement of the ordnance to an airborne position above the target position; and with the ordnance in an airborne position above the target position, one or more second control signals can be sent from the remote control device to cause the ordnance to descend toward the target position, and detonate the explosive component.
2. The method of claim 1 where the ordnance includes a mechanism by which an operator may, via an operation performed on the remote control device, cease motor operation of the ordnance to drop the ordnance from the first altitude and toward the target position.
3. The method of claim 2 where the step causing the ordnance to descend provides powered descent effected by transitioning blades from a lift or hover mode to a descent mode by reversal of blade direction of rotation.
4. The method of claim 1 where the step of sending the one or more second control signals ceases provision of powered blade rotation, causing the ordnance to descend under gravitational force toward the target position.
5. The method of claim 1 where the step of sending the one or more second control signals causes the ordnance to hover directly above the target position before descending on the target position.
6. The method of claim 1 where the step of detonating the explosive component is effected with (i) an impact fuse when the ordnance strikes a surface, or (ii) a detonator switch operable to detonate the explosive component. 42877007_1
7. The method of claim 1 where the explosive component is selectively effected by an operator with either (i) an impact fuse when the ordnance strikes a surface, or (ii) a detonator switch operable to detonate the explosive component and, if the operator of the remote control device desires to detonate the explosive component without deployment of the impact fuse, the step of detonating comprises operating the detonator switch with a third control signal transmitted from the remote control device to detonate the explosive component at or above the ground plane.
8. The method of claim 1 where the ordnance further includes a detonator switch operable to detonate the explosive component and, if the explosive component fails to detonate on impact, the step of detonating comprises operating the detonator switch with a third control signal from the remote control device to detonate the explosive component.
9. The method of claim 1 where the ordnance is deployed while being hand held by an operator.
10. The method of claim 9 where the ordnance is deployed by powering the ordnance while the operator holds the ordnance and then controls movement of the ordnance via the remote control device.
11. The method of claim 10 where a. the display is viewable by the operator; b. the operator observes the current position of the ordnance over the ground plane by looking at the display; and c. when the operator identifies a target beneath the ordnance via the display, the operator uses the remote control device to enable the ordnance to descend in a downward direction toward or directly upon the selected target.
12. The method of claim 1 where the ordnance descends from the first altitude in a vertical direction, relative to the ground plane, to the target position.
13. The method of claim 1 where the powered operation deploys the blades from a collapsed or retracted position to an expanded position for rotation and provision of the lift. 42877007_1
14. The method of claim 13 where the blades are spring loaded to effect deployment to expanded positions.
15. An aeronautical device for vertical take-off and flight above a ground plane, comprising: a case comprising an upper case portion and a lower case portion, the lower case portion connected to a bottom portion of the upper case portion; a plurality of deployable coaxial blades connected to the upper case portion such that, when deployed, the blades are rotatable about the upper case portion to impart thrust and bring the aeronautical device to a first altitude above a desired position; a motor attached to the upper case portion and connected to selectively provide power to rotate the blades to enable vertical take-off and flight; a payload attached to the case; an imaging system attached to the lower case portion, which can be oriented to generate image data representative of a view from the aeronautical device of a portion of the ground plane directly below the aeronautical device during flight, and a switch connected to drop the aeronautical device from the first altitude and on to the target, wherein one or more first control signals can be sent from a remote control device to navigate movement of the aeronautical device to an airborne position above the target position.
