Abstract
A long-distance drone is disclosed having a canard body style with a main body, a left main wing, a right main wing, a left forewing, and a right forewing. The left forewing is attached to the main body forward of the left main wing, and the right forewing is attached to the main body forward of the right main wing. There is a left linear support connecting the left forewing to the left main wing, and a right linear support connecting the right forewing to the right main wing. A plurality of propellers are disposed on the left and the right linear supports.
Claims15
A method of improving stability, robustness, endurance and durability of a VTOL fixed-wing drone, said method comprising:
- having a left hind wing, a right hind wing, a left forewing, and a right forewing, all of which being attached to a fuselage of the VTOL drone;
- providing no more than two linear supports to minimize drag, said two linear supports consists of a left linear support and a right linear support;
- connecting the left hind wing with the left forewing with the left linear support to minimize a contortion force applied to the fuselage during flight;
- connecting the right hind wing with the right forewing with the right linear support to minimize the contortion force applied to the fuselage during flight;
- having a first plurality of lifting propellers entirely disposed on an outside of the left linear support;
- having a second plurality of lifting propellers entirely disposed on an outside of the right linear support;
- locking the first plurality and second plurality of lifting propellers in a fixed position during flight while the first plurality and second plurality of lifting propellers remain entirely disposed on the outside of the left and right linear supports, respectively;
- wherein the left and right linear supports are spaced apart from the fuselage and provide enhanced overall integrity of the drone during flight;
- and
- wherein one of the at least three lifting propellers disposed entirely on the outside of the left linear support is disposed on a top side of the left linear support, and another one of the at least three lifting propellers disposed entirely on the outside of the left linear support is disposed on a bottom side of the left linear support.
