Disadvantages: the device cannot safely fly up to vertical obstacles.

The closest analogue is Bell Autonomous Pod Transport 70 (APT 70) - a four-rotor drone with two wings and four fuselages, equipped with a cargo compartment. The drone consists of four small aircraft fuselages with electric motors and propellers, united by two wings and two stabilizers. Between them is a streamlined cargo capsule.

Description

The unmanned aerial vehicle contains a frame 1, to the lower part of which are attached two piston engines 2, two drive shafts 3 with screws 5, three vertical stabilizers 8, at least two of which have built-in fuel tanks, and one has a built-in battery and a remote unit management.

Attached to the upper part of the frame 1 are four bearings 4, four air rudders 7, two propeller protective covers 6, an electric drive of air rudders 10, two horizontal stabilizers 9. Vertical stabilizers 8, horizontal stabilizers 9 and propeller protective covers 6 form a rectangular shape of the upper and lower sides of the unmanned aerial vehicle connected by longitudinal frame elements.

Device operation.

The start and control of the unmanned aerial vehicle is carried out using a remote control panel. When starting the piston engines 2, the torque is transmitted to the screws 5 through the drive shafts 3. On the drive shafts 3 there are bearings 4 attached to the frame 1. The bearings 4 give axial stability to the drive shafts 3. With an increase in the revolutions of the piston engines 2, the rotational speed of the screws 5 increases, this is leads to an increase in the air flow, creating a lift thrust, and the unmanned aerial vehicle rises above the ground. Below the propellers 5 there are air rudders 7 controlled by an electric drive of the air rudders 10. By changing the angle of inclination of the air rudders 7, the direction of the air flow created by the propellers 5 also changes, which leads to axial rotation of the unmanned aerial vehicle. Also, changing the direction of the airflow allows the UAV to move forward and backward and maneuver. When gaining speed and moving forward, the oncoming air flow will exert pressure on the horizontal stabilizers 9, which in turn will give the unmanned aerial vehicle a horizontal position, as a result of which the resistance will decrease, and the speed of the unmanned aerial vehicle will increase. Taking into account that the center of gravity of the unmanned aerial vehicle is located at the bottom of the frame 1, the horizontal stabilizers 9 will act as a wing, which will affect fuel economy. The higher the speed, the more horizontal the drone will be. With a set of speed and going into a horizontal position, the vertical stabilizers 8 will give directional stability and will serve as the keel of the aircraft. Takeoff, landing, maneuvering over short distances take place in a vertical position. Long distance travel is done in a horizontal position to save fuel.

The use of the proposed device will provide the possibility of close approach to walls, obstacles without damaging the screws.
