Problems solved by technology

[0004] Existing drones mainly use a simple box-shaped fuselage and a conventional hexahedron-shaped fuel tank, which has high flight resistance, low utilization of internal space, small amount of fuel, and short flight 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

[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 wing-body fusion design 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 fuselage ...

Abstract

A miniature multipurpose unmanned plane can be used for flight tasks of scientific research experiment, remote sensing detection and air aerial photography, etc. The unmanned plane ha the following characteristics: 1) long endurance time to facilitate flight task having high requirements on flight time; 2) simple usage to facilitate control; 3) good stability to suit carrying equipment of automatic pilot, aerial photography camera and camera, etc.; and 4) low requirements on rising and landing conditions. One the one side, a miniature multipurpose unmanned plane provided by the invention comprises a fuselage, wings connected to the fuselage, empennages, a tail boom for connecting the empennages and the fuselage, an engine (10) arranged on the front of the fuselage (1), a propeller (11) driven by the engine (10) and for providing pulling force required by flight of an airplane. On the other hand, an unmanned plane of the invention further comprises a modularization loading design, which comprises a base plate support plate (32), arranged on a middle part of the fuselage (1), for arranging airborne 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...
