Unmanned supply delivery aircraft
A method of delivering heavy payload using an autonomous UAV able to deliver supply by way of airdrop with more precision and at a lower cost. The UAV is equipped with two movable wing systems that rotate from a stowed position to a deployed position upon jettison of the UAV from a mothership. The UAV can be controlled remotely or it can operate autonomously and the movable wings can include ailerons to effectuate flight control of the UAV. The UAV can be reusable or can be an expendable UAV.
1. An unmanned delivery aircraft comprising:
a first portion including a fuselage;
a second portion coupled to the first portion, the second portion including a cargo hold;
a first movable wing system coupled to the first portion including the fuselage; and
a second movable wing system coupled to the second portion including the cargo hold,
wherein:
the second portion is separable from the first portion, and
at least one of the first movable wing system or the second movable wing system is pivotable from a stowed position to a deployed position.
2. The unmanned delivery aircraft of claim 1 , wherein the first movable wing system and the second movable wing system each comprise two wings, and at least one of the first movable wing system or the second movable wing system is configured to pivot between the stowed position and the deployed position.
3. The unmanned delivery aircraft of claim 2 , wherein:
a rotation angle between the stowed position and the deployed position is 90 degrees, and
wherein the stowed position of the wings is substantially longitudinally aligned with the fuselage.
4. The unmanned delivery aircraft of claim 2 , wherein the two wings of the first movable wing system are vertically spaced at different elevations relative to the two wings of the second movable wing system.
5. The unmanned delivery aircraft of claim 2 , further comprising a static line coupled to at least one of the first movable wing system or the second movable wing system to move at least one of the first movable wing system or the second movable wing system between the stowed position and the deployed position.
6. The unmanned delivery aircraft of claim 5 , wherein the second portion is coupled to the first portion by one or more fastening mechanisms.
7. The unmanned delivery aircraft of claim 5 , wherein the static line is connected to a drogue parachute.
8. The unmanned delivery aircraft of claim 7 , wherein the drogue parachute is equipped with a trigger mechanism to deploy at a predetermined altitude.
9. An unmanned delivery aircraft comprising:
a first portion including a fuselage;
a second portion coupled to the first portion, the second portion including a cargo hold;
a first movable wing system coupled to the first portion including the fuselage; and
a second movable wing system coupled to the second portion including the cargo hold,
wherein the second portion is separable from the first portion.
10. The unmanned delivery aircraft of claim 9 , wherein the cargo hold comprises a hollow cavity defined therein to allow for storage of cargo.
11. The unmanned delivery aircraft of claim 10 , further comprising:
braces included within the hollow cavity of the cargo hold to secure cargo; and
wherein the hollow cavity of the cargo hold includes a compartment that is separate from the fuselage.
12. The unmanned delivery aircraft of claim 9 , wherein the second portion including the cargo hold comprises an extension of the first portion including the fuselage.
13. An unmanned delivery aircraft comprising:
a fuselage comprising a first portion removably coupled to a second portion;
a first movable wing system coupled to the first portion of the fuselage; and
a second movable wing system coupled to the second portion of the fuselage,
wherein at least one of the first movable wing system or the second movable wing system is pivotable from a stowed position to a deployed position.
14. The unmanned delivery aircraft of claim 13 , further comprising a tail cone.
15. The unmanned delivery aircraft of claim 14 , wherein the tail cone is inflatable.
16. The unmanned delivery aircraft of claim 15 , further comprising a series of spring steel wires to hold open the tail cone.
17. The unmanned delivery aircraft of claim 13 , further comprising a drogue parachute comprising a trigger mechanism to deploy at a predetermined altitude.
18. The unmanned delivery aircraft of claim 13 , further comprising:
a static line; and
a drogue parachute coupled to the static line and at least one of the first movable wing system or the second movable wing system,
wherein deployment of the drogue parachute causes the static line to move at least one of the first movable wing system or the second movable wing system between the stowed position and the deployed position.
