VTOL Fixed-Wing Drone

Abstract

A long-distance drone having a main body, a left hind wing, a right hind wing, a left forewing, and a right forewing. There is a left linear support connecting the left forewing to the left hind wing, and a right linear support connecting the right forewing to the right hind wing. A plurality of propellers are disposed on the left and the right linear supports.

1 . A VTOL (vertical takeoff and landing) fixed-wing drone, said VTOL drone comprising:
 a fuselage;   a left hind wing and a right hind wing, both of which are attached to the fuselage;   a left linear support coupled to the left hind wing;   a right linear support coupled to the right hind wing;   a left forewing coupled to the left linear support;   a right forewing coupled to the right linear support;   a first plurality of lifting propellers entirely disposed on an outside of the left linear support; and   a second plurality of lifting propellers entirely disposed on an outside of the right linear support;   wherein the first plurality and second plurality of lifting propellers can be locked 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.   
     
     
         2 . The VTOL drone as recited in  claim 1  wherein the first plurality of lifting propellers has at least three propellers disposed in a linear array and the second plurality of lifting propellers has at least three propellers disposed in a linear array. 
     
     
         3 . The VTOL drone as recited in  claim 2 , wherein the linear array on the left linear support parallels with the linear array on the right linear support. 
     
     
         4 . The VTOL drone as recited in  claim 3 , wherein the left and right forewings and the left and right hind wings have no movable flight control surfaces. 
     
     
         5 . The VTOL drone as recited in  claim 3 , wherein at least two of the first plurality of lifting propellers partially overlap in their range of movement from a top view. 
     
     
         6 . The VTOL drone as recited in  claim 3 , wherein the left hind wing and the right hind wing are the rear most horizontal wings in the drone. 
     
     
         7 . The VTOL drone as recited in  claim 3 , wherein the left forewing is shorter than the left hind wing. 
     
     
         8 . The VTOL drone as recited in  claim 3 , wherein a center of gravity of the drone is disposed on a center longitudinal location of the fuselage, wherein the center of gravity is located at two third of a distance from
 a point A which is defined as a center of lift force between a foremost lift propeller on the left linear support and a foremost propeller on the right linear support
 to 
   a point C which is defined as a center of lift force between a rearmost two lift propellers on the left linear support and a rearmost two lift propellers on the right linear support.   
     
     
         9 . The VTOL drone as recited in  claim 3 , wherein a center of gravity of the drone is disposed on a center longitudinal location of the fuselage, wherein said center of gravity is located at one third of a distance from
 a point B which is defined as a center of lift force between a foremost two lift propellers on the left linear support and a foremost two lift propellers on the right linear support
 to 
   a point D which is defined as a center of lift force between a rear most lift propeller on the left linear support and a rearmost propeller on the right linear support.
