Problems solved by technology

[0003] Existing UAVs mainly use a simple box-shaped fuselage and a conventional hexahedron-shaped fuel tank, which has high flight resistance, low utilization rate of internal space, small amount of fuel, and short voyage time.
And most of them are tailor-made according to specific task loads, and the versatility of task load loading is not strong; it is not very convenient to carry out loading tests on loads that have not been formally finalized, and sometimes even the body structure needs to be modified

example 1

[0040] Example 1, long-endurance mission flight

[0041] The whole machine adopts wing-body fusion and "V"-shaped tail design and pull-in power plant, which has small resistance and high lift. Due to the installation of the embedded fuel tank in the form of alternate fuel supply, after the UAV takes off, the sequence of left rear fuel tank-right front fuel tank-right rear fuel tank-left front fuel tank is used to supply fuel to the engine in turn. During the process of fuel consumption, the whole machine The longitudinal change of the center of gravity is small, and because the fuel tank has a large volume, it can realize a longer flight.

example 2

[0042] Example 2, rapid replacement of airborne equipment in routine tasks

[0043] Due to the low cost of the modular design of the airborne equipment base plate, multiple base plates can be manufactured, and various required airborne equipment can be installed on the base plate before the field test. During the field flight test, the bottom plate screws can be removed, and the “airborne equipment-bottom plate” module can be replaced to quickly change the configuration of the drone’s airborne equipment.

[0044] Beneficial effect

[0045] The advantages of the present invention are:

[0046] 1) The small UAV adopts the layout type of wing-body fusion, single tail brace, V-shaped tail and pull-in power, which has excellent aerodynamic characteristics, especially the design of wing-body fusion increases the lift of the whole aircraft, Reduce wing-body interference resistance;

[0047]2) Embedded fuel tank design is adopted to make full use of the internal space of the fusela...

Abstract

The invention relates to a small multi-purpose unmanned aerial vehicle, which can be used for performing scientific experiments, remote sensing, aerial photography and other flight tasks. The small multi-purpose unmanned aerial vehicle has the following advantages: 1) the cruising duration is long, thereby facilitating the performance of flight tasks with high requirement for the flight duration; 2) the utilization is simple, thereby facilitating the operation; 3) the stability is good and is suitable for carrying autopilots, aerial cameras, video cameras and the like; and 4) the requirements for takeoff and landing conditions are low. According to one aspect of the invention, the small unmanned aerial vehicle comprises a body, wings connected with the body, an empennage, a boom used for realizing connection of the empennage and the body, an engine (10) arranged on the front end of the body (1), and an engine driven propeller (11) used for providing thrust for the aerial vehicle to fly. According to the other aspect of the invention, the unmanned aerial vehicle further comprises a modular loading design with a bottom board supporting plate (32) arranged in the middle of the body (1) used for installation of airborne equipment.

Description

technical field [0001] The invention relates to the design of a small multi-purpose unmanned aerial vehicle, which belongs to the field of structural design of aviation aircraft, in particular to the structural design of a small unmanned aerial vehicle that requires a relatively long endurance time. Background technique [0002] The cost of UAV is relatively low, it can avoid the casualties of drivers, and it can perform many tasks that man-machines cannot perform. It has broad application prospects. [0003] Existing UAVs mainly use a simple box-shaped fuselage and a conventional hexahedron-shaped fuel tank, which has high flight resistance, low utilization rate of internal space, small amount of fuel carried, and short voyage time. And most of them are tailor-made according to specific task loads, and the versatility of task load loading is not strong; it is not very convenient to carry out loading tests on loads that have not been formally finalized, and sometimes even re...
