Problems solved by technology

The disadvantage of this airship scheme is that the propeller is installed on the upper surface of the hull, and the axis of the propeller is perpendicular to the ground during vertical take-off, landing and hovering. At this time, the slipstream of the propeller directly flows through the upper surface of the hull, which is not conducive to generating lift. , and bring strong propeller-hull interference, which reduces the flight stability
[0005] Although the combined airship has many advantages, it has been stuck in theoretical and experimental research, and has nothing to do with the actual finished product application. To break through this situation, it is necessary to solve the problem of the combined airship-1. Overall design technology

Embodiment Construction

[0026] This implementation includes hull, wing, connecting rod, pod, tiltable power unit and control system. The airship's center of gravity is at 40% of the airship, where the connecting rods are placed.

[0027] The following will be described in detail in conjunction with the accompanying drawings, which are for understanding only

[0028] The hull is based on the NACA0020 airfoil in the early stage, and a symmetrical airfoil with a thickness of 50% is designed, and then the optimal symmetrical airfoil is redesigned through Fluent analysis. The structure diagram of the hull is established in sections by 3D design software, such as figure 1 They are airship bulkheads. After importing the project, using CAD and then using laser engraving machine, the skeleton is made of balsa wood. Since the skeleton only maintains its shape, the thickness and width can be appropriately reduced as far as possible to reduce weight. Finally, the PVC boat membrane is used to seal the skeleton....

Abstract

The invention discloses a dismountable tilting-power flying wing-type hybrid lift airship, and solves the problems existing in the aerodynamic optimization design of wings and a floating body, the design of a stabilizing surface and a control surface, and the connection mode of a nacelle, the wings and an airship body. The overall aerodynamic layout is determined through numerical analysis, and a fixed wing and a rotor wing are combined. In the respect of connection of the nacelle and the wings, the airship body is fabricated in three sections for allowing a carbon rod space to be reserved, and then the nacelle and wing motors are connected to the airship body by using carbon rods. The control mode adopts vertical tailless control, the direction of the airship is controlled through the differential motion between the two motors, and pitch control can be achieved by matching with a tilting angle. The dismountable tilting-power flying wing-type hybrid lift airship disclosed by the invention has the advantages of a fixed wing aircraft and a rotor wing aircraft, overcomes the disadvantages of conventional airships, and can be widely applied to military and civil fields.

Description

technical field [0001] The invention belongs to the field of aircraft design, and relates to a flying-wing composite lift airship with removable tilting power. Background technique [0002] An airship is a lighter-than-air aircraft propelled by power, and is also a type of aerostat, which uses lighter-than-air gas to provide lift. Compared with airplanes, airships have a lower flying speed, simple take-off and landing sites, and do not need long-distance runways. Compared with helicopters, airships have a large load capacity and extremely low fuel consumption when fixed. Therefore, airships can be used as a supplement to high-speed and high-energy-consuming aircraft, and can be used in civilian fields such as long-distance transportation, polar exploration, disaster relief, and live broadcasting; they can also be used in military fields such as search and rescue and coast guard. [0003] Modern airships are divided into traditional airships and combined airships. The combin...
