example 1

[0041] Example 1, long-endurance mission flight

[0042] 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 due to the large volume of the fuel tank, a longer flight can be achieved.

example 2

[0043] Example 2, rapid replacement of airborne equipment in routine tasks

[0044] 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.

[0045] Beneficial effect

[0046] The advantages of the present invention are:

[0047]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;

[0048] 2) Embedded fuel tank design is adopted to make full use of the internal space of the fusela...

Abstract

The invention discloses a small-size multi-purpose unmanned aerial vehicle which can be used for executing flight missions of scientific experiments, remote sensing detection, aerial photography in air and the like. The unmanned aerial vehicle has the characteristics that 1) the duration of flight is long, and flight missions with high requirements on the flight can be executed; 2) the use is easy, and the manipulation is convenient; 3) the stability is good, and equipment such as autopilots, aerial photography cameras, and cameras can be loaded; 4) the requirements on taking off and landing conditions are low. According to one aspect in the invention, the unmanned aerial vehicle comprises a vehicle body, wings, which are connected on the vehicle body, a tail wing, a tail support for connecting the tail wing with the vehicle body, an engine (10) which is arranged at the front end of the vehicle body (10), and a propeller (11) which is driven by the engine (10) and is used for supplying a tensile force necessary for the flight to the vehicle. According to another aspect in the invention, the unmanned aerial vehicle further is in a modular loading design and comprises a bottom plate support plate (32) which is positioned in the middle of the vehicle body (1) and is used for mounting vehicle-mounted equipment.

Description

[0001] This application is a divisional application of Chinese Patent Application No. 201010127939.6. technical field [0002] 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 [0003] 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. [0004] 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 con...
