Abstract

A micro-unmanned aerial vehicle deployment system is provided for a cruise missile having submunition compartments. The system includes a vehicle launch module releasable from the cruise missile submunition compartment. The vehicle launch system has a control circuit and at least one micro-unmanned aerial vehicle contained therein. Structure is provided in the launch module for deploying the micro-unmanned aerial vehicle. A separable tether can be joined between the cruise missile and the vehicle launch module that separates when subjected to tension after deployment of the vehicle launch module.

Claims

1. A micro-unmanned aerial vehicle deployment system for a cruise missile having submunition compartments therein, said system comprising:

a vehicle launch module positionable in one said submunition compartment of said cruise missile and deployable from said cruise missile;

a control circuit positioned in said vehicle launch module;

at least two micro-unmanned aerial vehicles stacked in said vehicle launch module such that the bottom surface of at least one micro-unmanned vehicle is proximate the top surface of at least one other vehicle, said micro-unmanned vehicles being oriented in the same direction, said micro-unmanned aerial vehicles each having a propulsion means and wings fully configured for flight;

a micro-unmanned vehicle deployment means joined to said control circuit and positioned to deploy at least one micro-unmanned aerial vehicle; and

releasable means attachable between said vehicle launch module and said cruise missile.

2. The system of claim 1 wherein said micro-unmanned aerial vehicle deployment means further comprises:

a shell having separable walls defining the portion of the vehicle launch module having said at least one micro-unmanned aerial vehicle positioned therein; and

latches joined to said control circuit and to said separable walls of said shell for separating said walls after deployment.

3. The system of claim 2 wherein said latches are pyrotechnic devices that separate said walls of said shell when activated.

4. The system of claim 2 further comprising at least one activation switch joined between said shell and each said at least one micro-unmanned aerial vehicle, said switch being capable of activating said associated at least one micro-unmanned aerial vehicle on release from said shell.

5. The system of claim 2 wherein said micro-unmanned aerial vehicle deployment means further comprises a plurality of spacers positioned between said shell and said at least one micro-unmanned aerial vehicle.

6. The system of claim 5 further comprising at least one activation switch joined between said shell and each said at least one micro-unmanned aerial vehicle, said switch being capable of activating said associated at least one micro-unmanned aerial vehicle on release from said shell.

7. The system of claim 1 further comprising a parachute joined to said vehicle launch module, said parachute being deployable to slow the descent of said vehicle launch module upon deployment of said vehicle launch module.

8. The system of claim 1 further comprising an activation switch joined between said micro-unmanned aerial vehicle deployment means and said at least one micro-unmanned aerial vehicle, said switch being capable of activating said associated at least one micro-unmanned aerial vehicle on release from said micro-unmanned aerial vehicle deployment means.

9. The system of claim 1 wherein said micro-unmanned aerial vehicle comprises an aerial vehicle that is remotely controllable and capable of controlled flight.

10. The system of claim 9 wherein:

said micro-unmanned aerial vehicle has at least one environmental sensor positioned thereon; and

said micro-unmanned aerial vehicle is capable of transmitting information received from said environmental sensor.

11. The system of claim 1 further comprising a separable tether joined between said cruise missile and said vehicle launch module, said tether separating when being subjected to tension after deployment of said vehicle launch module.

12. The system of claim 11 further comprising a parachute joined to said vehicle launch module, said separable tether being operable to help deploy parachute and slow the descent of said vehicle launch module upon deployment of said vehicle launch module.
